Chevy Silverado and GMC Sierra Starting Problems

  • have same truck & same issues. please tell me you found out and fixed the problem so you could let me know what to do. I've replaced battery, alternator, fuel pump & filter. But not the ignition module or switch yet, which could be next. Rarely, after wiggling the the steering column the gauges would turn on, hear fuel pump & it starts; any suggestions?
  • I might have an idea for you I have a 2008 Chevy Silverado doing kinda the same thing. It is probably a short in one of the ignition wires in the column.
  • I have a 2008 Silverado, Mine is doing the same thing. So far I can tell you its not the alternator, starter, any of the connections or the battery. But what i can tell you is that its probably a wire inside the steering column. I haven't checked mine and found out it to be the problem but I am pretty sure it is.
    let me know how yours goes.
  • I have a 2008 silerado as well that has the exact same issue. I have had it towed three times now to the dealership (Third time today) and they still have no idea what is wrong with it. First they said it was the starter relay loose but I know its not that. Then they said it could be the encryption in the keys. Its not that. I have absolutely no faith in this truck and the wartantee is up in 5 months. If anybody has a resolution to this I would love to hear it. I do not know what Chevy will do with this one as it is happenening every month now. I have been lucky that the three time this has happened I have been locally in town but I live in Alaska and if I am out fishing somewhere in the middle of nowhere once it gets nice out, no cell phone reception and come back to a truck that won't start again I will be in for a bad day.

    Thanks
  • I figured it out! I have been having the same problem for about a month now. It was a real crap shoot on whether or not my truck would start. It came to a head yesterday because it was happening more and more often til yesterday when I could not get it to start at all. I have done almost everything on this blog that has been suggested and none of the suggestions worked. One blog spoke of an electronic neutral safety switch on the left side of the transmission. I unhooked the two wiring couplings from the neutral safety switch and it still acted that same way. I took the neutral sfety switch off of the tranny and hooked the wiring back up. I rotated where the shifter changes the gears to where i thought neutral and park was at and wala, it started. I went to the parts store and bought a new neutral safety switch and replaced it. After approximately 30 minutes labor (easy) and $40 for the part, Im back in business. It has started fine every since.
  • I have a 2008 Silverado Max that has 24,000 miles on it. I have had there times now in the past three months where I go to turn the car on and the lights come on and all instrumentation is fine but the truck does not turn over at all. I have had the truck towed to the dealership three times now. The third time this happened was just yesterday. I spoke with teh service rep at the delaership and we went through what they had thought it was wrong the past two times, key loosing its encryption to computer (Not the issue) They thought the starter relay was loose. (Not the issue) right now I have absolutely no faith in this truck and I live in Alaska so if I am out in the middle of nowhere fishing or something with no cell phone signal I am in a bad situation. I only have 5 months on the warrantee and the chevy service guy already stated they "Seem to have an issue dianosing the issue." Does anybody know what I can work with Chevy on if they can not resolve this issue. If they can't fix it do they need to replace due to warrantee and what type of documentation should I be sending to Chevy now. They have no idea why the truck would eventually start working and work for about a month until it decides to not run again.

    Thanks,
  • Found It, Fixed it! Called the ignition switch-a wiring harness within steering column/lower dash. Bought brand new w/lifetime warranty @ O'reilys for 139. Couple hrs labor. Starts like new every time. BEST instructions for removal w/pics & step by step @ www.sparkys-answers.com/2008/12/1996-chevrolet-1500-truck-ignition.html. No sign in, they forget to mention an E4 & E5 star socket needed. Also, clean & tighten the ground wire for fuel pump located under truck, next to gas tank, on TOP side of frame. Heavy corrosion/dirt and loose will affect starting. Easy to check and has happened before.

  • I have a 2009 2500 chevy with low miles on it. The last time i was using it, i parked it outside and shut it off. after about 20 minutes i came out to put it inside and it wouldn't start at all. It makes clicking noises. I ended up jumping it to see if that would work, and it started right off. Ever since then it has run fine, until this morning i had the same problem. I haven't jumped it yet, but have tried tapping the starter and the gas tank to see if that helped, which it didn't. Any ideas?
  • Nevermind!!! I drove this truck (2003 GMC Sierra) only a few times since I replaced the neutral safety switch and it did fine . Now it wont crank at all. Doing the same thing. Turn the key and nothing. Battery is fully charged. NOTHING! I am at my wits end with this truck. Has anyone figured it out yet?

  • We have a 2003 Chevy pickup that is doing the exact same thing, we have tested the battery, changed the ignition switch, now we are going to have to tow to a mechanic. If anyone finds a solution, PLEASE share. As for taking it to the dealership, it sounds like many of the people here that have done so have spent a lot money getting several things replaced, but are still having the same issues.

    Christina,
    I am having the same problem with my 08 Silverado. It wont start. This has happened to me twice now and it is currently at the dealer, but they cant find anything wrong with it . There is a problem and I want it fixed. I have only had this truck two weeks. The dealer I bought it from is going to pay to have it fixed, but they have to be able to find the problem first. The first time it happened, the engine code said to Service the Theft Deterrent System. The second time it happened, no code would come up. I have also been told from others that they beleive it has something to do with the OnStar system. Can you help me !!! Please !!!

  • I have a 2005 Silverado 1500 crew cab that I bought last fall. Love the truck, but I've had four occasions where it wouldn't start - had full power, but wouldn't make a noise or turn over. Had it towed to the local mechanic, who didn't have the diagnostic equipment, but checked out battery, alternator, etc. and all checked out fine. Started on its own a few days later. Did the same thing again a few days later, but then did start later in the day so I drove it straight to the dealer, who put it on machines, but couldn't find any problem... never did it there. Brought it home and now it's done it again yesterday. Tried to start again this morning and nothing. This is really stressful... I'm a single parent and can't be stranded places! Bought a nice truck for reliability and am very stressed and worried about being left stranded again somewhere. Please help!

    Tricia,
    Thank you for replying. The Chevy dealer finally got the truck to not start and tracked it down to the starter. The starter armature has a bad spot in the comm, and everytime it would happen to stop in that exact spot it would not start. So, they replaced the starter and said that it is fixed. I hope it is. I dont want this happening again. For now I am good to go, but if it happens again, I will contact you with the info you need.
    Again, Thanks

  • 1996 chevy 5.7 I have to turn the key on wait for the pump to cycle then bump the starter I will have to do this 5- 10 time if the truck has sat for awhile it will start with out turning the motor over completly just from bumping the starter and once going it goes great no issues ?
  • Dear GM customer service:
    I have a 2008 Silverado I purchased new with a similar no start situation now 3 times.
    Each time the truck is running fine and turned off only to find out I cannot restart the truck within the nect hour. The battery, lights, remote etc all work flawlessly and the voltage checks out fine before and during starting attempts. The 2nd time this happened I called the warrantee number and the truck was flatbedded to the Chevy dealer on a Saturday morning. After calling in all day Monday I finally just git a ride to the dealer at 5PM to learn they were just getting to it then. Since it started for them they returned it to me saying they had no error codes and it was fine and there was nothing else they could do.
    I must say I am a bit concerned that this has happened 3 times and that there appears to be no correction for the problem - it is not fun to be stranded and not know when it will happen next. I called service a couple of times now asking what to do next but have no answers at this time. Since I will be reaching the end of my warrantee period in a few months it is even more concerning.

    All of this and my contact information is traceable through the Vin ....

    Last call to the warantee center was on 3/27/2011 - please help.

    I have a 08 gmc sierra 2500hd 6.0l crew cab runs rough when i come to a stop after driving more then 17miles or is warm, and the engine has a vibration in the morning when its cold, almost like engine mounts are broken. dealer replaced them under warranty and its still there. truck has only 25,000 miles. has any body have any problems like this, dealer said it was normal to me its not, please help me or give me some kind of help. thank you.

    the truck is a 91 gmc k1500 305 and this is a real brain teaser... here is what I have replaced; air cleaner, fuel filter, O2 sensor, throttle position sensor, egr valve, plugs, wires, distributor cap and rotor, pcv valve, grommet and hose, I have also rebuilt the TBI all new rings and gaskets. here is the problem that still remains. some times when I go to start the truck it turns over but idles rough and then dies if I don't give it gas some time even if i give it gas it still dies. the more annoying problem is after driving for awhile is will sputter and if i let off the gas and baby to throttle it will stay going and get back up to speed. at times it has stall completely when pulling out from a light. any direction would be great. also the catylitic converter is gone and the muffler is shot do to a bad back fire but I had this problem before any of that happened. PLEASE HELP I am going crazy.

    smitty477,
    Yes, so far replacing the starter has worked. It has been two weeks since I had it fixed and no problems so far!!
    Regards,
  • My chevy sat for about 8 days, then finally started again. Drove it straight to the dealer. Wouldn't start for them the next morning (a miracle). They replaced the starter and battery. So far, no problems, but I hold my breath every time I turn over the key.

    I had selman chevrolet look at it they had it for 2.5 day, and the service manager call tech support at gm to get some info, after they drove the truck and did some reserch he said that its normal for that truck to run rough at idle. some of my friends have the 6.0l and there truck runs smoth. I just cant belive that a dealer is telling me that a engine with only 25000 miles, its normal to run like crap at times, if there is some thing you can help me with i will bee more then thank full to you.
