Hard Cold Start

Up here in New England, it's been a very cold and snowy winter so far, which my truck doesn't seem to care for too much. When I start it up in the morning (which is usually in the 20s), it takes a long time for the engine to turn over. After a while it begins to sputter then finally turns over. When the engine is running however, there are no problems with it whatsoever and it runs like a champ.

 

Theories I've heard about this problem so far:

1. Distributor worn out (which doesn't seem likely)

2. Fuel Pump not generating enough pressure (which seems more likely)

 

I think this has something to do with the fuel pump taking a while to build up sufficient pressure, but I'm not sure of it. Rockauto has some decent prices on fuel pumps if that is the problem, but what would I need to do in this instance? Replace the filter, pump, wiring harness, strainer or something else?

When you say 'slow to turn over', sounds like a weak battery to me.

The battery is new as of April, so I don't think think that's the cause. The electricals all start up immediately, but the engine doesn't...

like do you sit and crank on it and it takes a while to get gas or does it just crank slowly?

 

if it's the cold.. park in the garage? :uhoh:

I sit in it and it takes a while to get the gas. What's odd is if I turn the key, stop, turn it again, stop, then turn again, it will start. It's not like when you have a weak battery and it chugs before it starts...so I guess I was unclear with my description, but I've never had this problem before.

 

I would park it in the garage, but there's no room for my truck. I don't think the clearance is high enough for it either.

99% sure its your fuel pump. If you can, hook up a pressure gauge and post back the readings at starting and runnning.

Did you ever figure this out? I'm having what sounds like the same problem, but I am not sure if we are actually describing the same thing.

 

I turn the key and the starter will catch and turn over maybe once, then nothing, then as long as I keep holding the key down, it eventually gets enough juice and it starts cranking normal and the motor will start.

 

The clock and everything are reset every time, but lights and everything come on.

 

I think it's a ground problem.

 

Is this the same as yours?

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      By Brendan C · Posted

      New to diesel trucks. I happened to find my oil cooler leaking oil externally with only 4,000 miles on the truck. I didn’t realize this was an issue until I started researching it. Dealer is going to replace it under warranty but I’m wondering if there’s anything GM is working on to fix this issue. I’ve heard the oil filter used is the same as they use on their V6 motors and that’s what is causing the problems. Should I switch to a bigger filter or keep using the OEM recommended?

      Seems to be Missing a lot of Updates

      By Vu1can · Posted

      So, GMCustomerService:  Judging by the Update History pictured above, is this truck missing any updates that it actually needs. If it's just for the infotainment system, the radio is working fine and no trouble with SeriusXM. and Android Auto is working fine wirelessly with my phone. Some months ago, an update notice was sent to my truck. I approved the update and it finished saying that the update was successful, but it seems that whatever that update was, it didn't actually get installed - at least not if I'm to go by the Update History shown above.   So, again, are there any updates that this truck really should have? I've checked with my dealer but they're reluctant or commit to anything and if I want them to check, they require a $200.00 fee just to check it out and then I'd have to pay for the actual update(s).    Ignorance is bliss, and if none of the updates goes to fixing any mechanical discrepancies, I'll just leave things as is.

      Electrical Problem - solved

      By CNH-320 · Posted

      Hey everyone, I recently had an issue with my 07 2500HD GMT900. My DRL’s stay on at all times. Right front turn and right mirror turn signal indicator stay on solid at all times. By “at all times” I mean the only way to make them go off is disconnecting the battery. I tore the headlight assemblies out, tried disconnecting the harnesses to eliminate bad wiring at the harness, I unplugged the headlight switch, no change and the mirror turn signal still stayed on. My first thoughts were : Bad bulb and/or socket somewhere, under hood fuse panel bad, bcm bad, tail light or trailer wiring problem, or some random short to power in the harness.  Possibly a bad ground but unlikely. I had a big clue in the fuse panel, it had a burnt smell. I started pulling every fuse that had to do with DRL or right turn/park lamp. Nothing made the right directional turn off but pulling the DRL2 fuse made the DRL’s go out.  After studying wiring diagrams, I found that both problems had that fuse panel in common, the bcm also controls both problems but knowing the fuse panel had a burnt smell I removed and disassembled the fuse panel and found a little corrosion on the printed circuit board.  I ordered a new fuse panel from Amazon for like $260. When it arrived I installed it, and put everything back together, the problem was fixed. I figured the fuse panel needed to be replaced anyway so that was a logical place to start. Hopefully this story helps someone in the future. Regretfully I didn’t scan for codes before I did everything.

      That stinks. I’m sitting on the side of the road right now with the same issue. Never had an issue before taking it in for the ground strap recall. Now I’m outside of warranty and they’ll probably want $200 just to diagnose what they already “fixed”.
