Remote start - no crank

ive got a 14 sierra SLE and it seems that the remote start dies every other day.

i hit lock 2x then push and hold the start, lights flash then no crank.

next day works every time...

 

ive taken 2 videos of it now to show my dealership, it is a intermittent issue but annoying as hell when you want to arm up the truck because its -20 get out there only to see ice still on the windshield and a cold engine....

 

anyone else have remote start issues?

 

dealership (who im on extremely good terms with) is aware of the issue, but i havent had them look at it yet.

 

does anyone know what the remote start perimeters are?

run time(10 min i believe), max temp, how many times it will let you start it in a row (if its even limited) and any chance that it has issues when below certain temps?

 

edit - watching my videos its had to tell that im double clicking...ill have to make another one for te dealership and i guess narrate what im doing.

Push the lock once.

 

Push and hold the crank for at least 4 seconds.

 

I often start it from a position where I can't see it. I use a count of 1000, 2000, 3000, 4000 to be sure I hold it long enough (learned to pace the count by counting while watching/listening to truck)

 

You get 2 starts, then ignition must be cycled with the key.

 

Each start is 10 minutes.

 

If the the second start is done while the first start is running the truck will still shut off 10 mins after second start.

 

Remote start will not operate if hood is open, the key is in the ignition or if there is an emission fault and the CEL is on.

 

The engine will turn off during a remote vehicle start if: The coolant temperature gets too high or if the oil pressure gets low.

Did you use the OnStar Remotelink app? I've had a couple times where I would play with it using it to remote start the truck and shut it off with the app, just seeing how long it takes to do it. After I do that the key fob remote start doesn't work unless I start the truck with the key. So maybe that's what's happening to you. I guess it's a safety feature where if you use your app that it won't let you use the key fob until you put the key in.

thanks for those specs.

i was within range...about 4 or 5 feet away when i made the video. i usually park against a brick wall in the parkinglot at work so when i lock and start i can see the lights flash/glow against the wall (at night)

i know i held the button long enough, truck made the flash of the headlights to acknowledge that i had held the start.

this is a possibility...honestly you guys are going to say im wasting fuel like crazy but on extremely cold days(below -20) i usually use the app from my office about a hr before i leave, let it time out, then fire her up again and let it time out.. then fire it up as i walk to my truck from my office (5 to 10 min walk...long walk though the building and long parkinglot)

then if the last start times out i usually start is when im within sight of the truck.

now, with the info posted above about you only get 2 starts then need the key i wonder if i really got 3 remote starts from the app.. but i know up til last week i was able to start it as i walked to the truck.

 

but to take the onstar app out of the equation, this morning at like 430 am i had to get up for work, fresh start no use of remote app and she didnt start....so i dont think the remote app is a factor.

what was the thing with the exhaust overheating in cold weather climates??

is tat from the servo in the exhaust (the flapper valve) i havent made any changes to mine, maybe thats part fo the issue.

i know they are used to create more backpressure for more low end torque. (my bike has a electronic one on it that i really need to get rid of...)

 

i wonder if my remote start issue is because of a frozen servo.

so the remote app is no longer a factor....

 

today leaving for work at 5am is was -25 out (give or take a little..) i used just the key fob remote heard the honk from inside my house and assume she fired up.

went outside to a cold truck...not impressed but again now this is on camera as well as i have cctv on my house. dealer has yet to see the vehicle for this issue...and its reall the only issue ive had)

i cant take it in this week now, i got stuck with a bunch of overtime i didnt want... so hopefully next week i can get in to the dealer.

Did you have the parking brake engaged or the hazards? Remote start wont work when either of those are engaged.

Not true. It might not work with hazards on, but I make sure to always push the parking brake in at home since it's on a slight hill and I park on the street. Everytime I start it up in the cold I do remote start from inside the house and it has no problem starting with the parking brake on. I push it in all the way also. The only time it didn't remote start with the fob was because I played with the Remotelink app on my phone and apparently it's a safety thing where if you use the app then the fob doesn't start it unless you go and put the key in it.

parking brake is always on when shes parked.. old habit from driving a manual.

i dont think ive ever even tested the hazard light switch on the truck lol (and ide rather not need to)

You only get 2 starts.

so i figured out the issue, it was the remote.

i switched to my other remote and its been working fine since.

 

i had one of the remotes replaced at my first service, so i suspect this may be the one that is causing the no-start issue.

    • I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.
    • An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
    • There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.
    • The only problem I have seen this cause is longer crank times. 
    • Injector is being sent off today for rebuild and I estimate I'll have it back in 10 days or so.   It may not be the injector...of course...now that I've torn down the intake again. But, let's rule out the injector and replace those spider legs that have been almost rubbed through.   The truck has always had negative timing and I'm reading "normal" timing at warm idle should be +16 or so. I'm negative 16 to 25 or more, and it's always been like that since I bought it.   A light turned on upstairs last night in the old noggin. Rare, I know...   This will be wild, if it turns out to be the cause!   In 2001, according to the old service documentation, the muffler was replaced. Why? I have no idea, it wouldn't have been rusted through by then. But they did a crappy job.   In 2019, another shop replaced it and noted the prior install was poorly done on the work order. "Exhaust system vibrates on crossmember". Except...I guess they just left it be? I believe the husband, the couple who were original owners, had passed by then. Maybe she said it's just not worth it to have the exhaust system fixed and declined repairs. Very few miles were driven between 2019 and 2025.   The exhaust system vibrates heavily on the crossmember and you can feel it and REALLY hear it, even today. Not always, but at idle, it gets going pretty good sometimes.   What if....   ....What if that's enough to trigger one or both of the knock sensors? Could it be tricking the sensors into sensing knock, so it's pulling timing aggressively? Pulling timing heavily means it's firing after the piston reaches full height which means incomplete burn which means the O2 sensor is sensing a rich condition, which means I've been chasing my tail, and what I thought was an inconsequential problem (janky exhaust) has been THE issue for this truck for 25 solid years?   That would be wild. Maybe it IS wild.   The service documentation thereafter, for years, shows visits for rough idle, replacing O2's, replacing the cat, replacing plugs and wires, a misfire condition, like they could never solve the issue. The injector has been replaced 4 times in 80k miles, that's just crazy.   The secondary theory....   The engine has clearly had a leak at the front seal for a very long time (the greasy trench...). I think the truck changed hands quickly ~2025 because there's Napa receipts from someone I don't recognize in the ownership history. They apparently replaced the timing cover seal, and they did a terrible job. There's RTV smeared all over and the leak I had reduced to a weep by snugging the front oil pan bolts is now a leak again.   HOWEVER....I read about replacing the crankshaft position sensor. Any time the ckp sensor is disturbed or timing cover is removed, the truck requires relearning, and that can only be done through a bi-directional scan tool. Skippy with the RTV probably didn't do the relearn procedure is my guess. His scan tool is lost in a pile of RTV goo somewhere.   So, it's very possible the sensor has been disturbed and the truck is just running on the old learn data but not setting a code for anything. The distributor has since been replaced and so has the camshaft position sensor, so all bets are off for that thing.   In the theme of one step forward, two steps back, I returned the accumulator for the AC. The gal I've been working with at O'Really's has been great. She refunded it under manufacturer's defect and we compared it to the replacement I ordered, and sure enough, the replacement is machined very differently (and a gauge actually fits on it!).   Got it home, installed it, started vacuuming it down.... and I couldn't get good vacuum.   The high side service port, where I replaced the old GM ball valve suspecting that was a source of the previous leak....well, I've clearly exposed whatever pre-existing crack in the line where the service port is welded, and made it much worse. Blessing in disguise? Except there goes another $25, now I'm waiting for a replacement AC line.   In 10-ish days ALL the parts will be here. Rebuilt injector, new exhaust system, new cat, new high pressure AC line.   Oh, did I mention the squeaking ISN'T coming from the AC pump? The truck still squeaks when started, and there were words after I started it with the new AC pump installed. But, there was more to replacing the AC pump for just a squeak. A truck with good working AC is something of value, for the comfort alone.   I've ordered a new harmonic balancer because, 30 years is a good run for one of those. Rule it out. The squeak may be something more sinister, though. I'm worried about that ckp sensor and if it was shimmed correctly, or if the timing set was installed correctly. The squeak may be coming from UNDER the timing cover.   At this point, once I get it put back together, I'm thinking I'll take a 50 mile victory lap and then promptly put it up for sale. This truck is cursed. Betty, from beyond the grave, doesn't want anyone messing with her Blazer. Or maybe she's getting revenge for 30 years of shop visits with that thing.
