Hey new here, I have a 07 NBS Silverado 4.8 4x4 that has a no Crank no start issue. Never had this issue usually starts right up. So drove to the gas station one night recent and Midway got a reduced engine power and died, would not start back up at all, had it towed and have been checking certain things battery, starter, fuses I've read alot on here and other sites. I figured maybe some insight to my case would be of help. I don't hear a click at all when trying to start it simply does nothing. I've tried a new battery , I've checked cables power and ground cables. Checked mega fuse and lightly checked relays kinda new to the checking relays other fuses I've checked for continuity and they check out fine. I've read about a security issue maybe but I don't have the indicator on my gauge. Anyways any insight is greatly appreciated , I miss this truck it's one string running engine and has got me and my family by for many years.
I am sure this has been brought up in other Topics but I cannot seem to find an answer so here it goes... I have a 2007 GMC Sierra SLT CCSB 4x4 5.3L M engine, on Saturday afternoon I disconnected the ground on my battery to add an aftermarket sub and amp tapped off of the Factory Bose amp. After wiring everything up correctly (just running wires) not even installing the amp or subs I decided to reconnect my Battery and fire up the truck... Funny thing is after plugging it back up and going to start it, it immediately said Service Air Bag, and would not start.. I have checked fuses under the hood, under the dash and on the instrument cluster fuse box and all my fuses are good and working! All doors, windows, lights, remote lock, unlock and alarm work but the truck won't start I have tried the 30min key relearn and redisconnecting the battery for 30 min. Normally my truck has a TPMS Service light on due to me having a bad sensor but it isn't even on right now! Everything works but it just won't even crank it just dies in a sense (it acts like it loses power but as soon as I release the key from start position everything comes back (lights up as normal) seems like I am locked out of the system. Scanned with a Snap On code reader with personality keys... I get a B1370, B1011, U0140, P0690 and a airbag code that I don't recall (I'm at work) after clearing the codes only the B1370 and the Airbag code return.The Service Engine soon light isn't even on either I only get these codes with the snap on scanner.. they don't even show up on my basic scanner.. Yes the battery is good also tried jump starting it just in case checked all fuses and relays, starter works with forced relay and key on but will not start also replaced my ignition switch. Another off topic question is what does The TP in the under the hood fuse box diagram mean? it has it near the 41 Fuse it says TP twice then at the bottom it says TP and has like a book with a key next to it... I'm at a loss right now with what the issue is any help is Appreciated!
Hi all, Im new here to the site as of today (9/01/16) and I just bought my new (to me) 2007 gmc sierra 1500 2wd. Ok so I have had this truck for roughly 2 months and I picked her up with only 47k miles! which is fantastic and all but I am having a really bad vibration only on the highway like clock work as soon as my speedometer hits 75+ it seems to me to be coming from the front but it is really hard to tell especially since it shakes my whole truck. everything in the front suspension seems to be really good and tight. so im lost as to what is causing this annoying problem. any help or info would be appreciated! also, every time I brake and or start off the line it clunks in the rear pretty bad. not every time but 80% of the time it does this clunking in the rear. now I know most of these trucks bind up when braking or taking off from the weight of the truck either going to the front or the rear while stopping or starting. which makes since honestly. but this clunk is way more noticeable and harsher. I think it is the slip yolk on the drive shaft that is slipping and I think it needs to be removed and heavy duty grease put on the yolk. if any of you guys are experiencing this issue as well please tell me how to get rid of it. Thanks a lot. and have a blessed day!
I'm getting ready to do a brake job on my truck and I've been noticing a roaring sound as I drive. The sound is usually louder when I'm going more slowly but I'm thinking engine and road noise could be masking it as I go faster. I figured that while I was under there I'd check the bearings. I went out to YT to see if there were any videos on the subject and there was one, but in it, he simply replaced the whole hub bearing assembly. Is this how bearings are serviced now? You don't fool with individual bearings and packing them with grease nowadays? I guess I'm behind the times if so! Mike
