#414 of 492 02 Silverado 8.1 starting problems
Jul 07, 2012 (10:19 am)
My Silverado began stalling, having a hard time starting, running rough when it first started, and taking several seconds to idle down after I pushed in on the clutch. Recently, I must now pump the throttle on the fuel injected engine to get it to start and barely stays running for a few seconds until it catches hold. About the same time, when pulling, the rpms increase and stay in the 2500 range. Are they related? Any ideas where to start? No codes are showing.

Yay !!!!! Its fixed, but the dealer didnt fix it. My husbands buddy said lets check the fuse box and the Start/run relay was about half out with 2 prongs in and 2 just touching. It seems that the cover was letting it come up at times so that the 2 prongs lost contact and it would die or not start, they put it back in and havent had any trouble since. We even went to Tenn. last week with no problems. Obviously the dealer didnt bother to check the fuses, the cover didnt even have fingerprints on it. So 2 computers, reprogramed, new module under the bed and 2 mths of aggravation was all over a little relay. Though we dont know how or when it got bent, if you are having trouble replace that relay first!

I will join the lot of you with my 2006 GMC Sierra 1500HD with only 17,700 miles on it! Sunday my keyless entry fob would not work, so I entered my truck with the key. Same story as all of you, it would not start. I contacted GM customer service Monday and I was instructed to place the key in the ignition and set to accessory only and wait 2 minutes and try to start the truck. If this didn't work try it again. Well, it didn't work after trying all day Monday and Tuesday morning. After I called my assigned personal GM service rep and left a message as to the failed attempts to start, I got a call back later in the day from GM customer Service and they said I needed to have my truck towed to a dealer. Have you tried to find a GMC truck dealer lately? (they are farther and fewer between) 3 dealers with in 10 miles have all gone belly up. Prior to calling for a tow I pulled all of the relays from the fuse blocks and pressed them back in, checked all neccesary fuses, but this didn't help either. I called GM roadside service and they sent out a local tow truck for an up front amount of $85. The driver showed up, hooked up his cables to the back of my truck, pulled them up tight with a slight jerk and walked around to the driver side door of my truck, put the key into accessory mode, all of a sudden the radio, the door chime, enterior lights, and even the window worked when the tow truck driver pressed the down button. I told the driver to stop, the system is working all of a sudden, try to start the truck. Wow! it started and I had him disconnect his cables. I was not about to have a dealer tell me there was nothing wrong with my truck for some un Godly fee. I drove the truck all day and every thing is fine. I contacted GM roadside assistance and had the towing fee changed from $85 to $60 for the service call. So the BIG question is. What caused the truck to start? Was it a delayed reaction to re-setting the relays, or the tow truck driver jerking on my truck while set in Park with his cables. The tow truck driver may have had the key in the ignition but not turned on for a good 10 minutes, I can't imagine this helping. But the saddest part of my story and all of the other stories told here is GM does not know what causes this event to happen. But their dealer can surely get to the bottom of it. "Right" Thanks everyone for your comments and I hope mine will help someone else.

One day after my truck misteriously strating working it quit again today. This time I couldn't even lock it. So I got back in and tried to strat the truck, no luck.
So, from what I have learned so far I put the key in the ignition, turned the key to accessory, put the transmission in neutral with my foot on the brake, and released the parking brake. WaLa! Everything came on and the truck started with no problem. So I think this issue with not starting has a connection to the parking brake and being in park. Since pressing the parking brake pedal is pretty standard stuff, something else must be triggering the problem. Maybe it has a sensor on the parking brake adjustment, I am just guessing. I keep you all posted as I narrow down this annoying issue and maybe share it with the GM guys who don't have a clue.

It now has come down to a flooded engine. What controls the fuel going into the injection system when engine is turned off? Fuel is getting by after shut-off.
#420 of 492 Silverado Rough Start Up
Jul 30, 2012 (3:45 pm)
I have a 2007 Silverado. 8 months ago it was "bucking" on start-up and after 8 days of missed diagnostics, the dealership replaced the fuel pump and it solved the problem (temporarily). 8 months later - exact same symptoms, now 4 days later - still no resolution. They say it is not the same problem. Has anyone else had a similar issue. The "bucking" seems to smooth our after about 15-30 seconds, but it still doesn't seem to idle like it did prior to the rough startup.

OK, Its been 3 weeks since I've been here and my 2006 GMC Sierra still has on occasion not wanted to start. So far I haven't figured out what causes this event, but I can say every time it does happen, I put the key in the ignition to the on mode, place the transmission in Neutral, release the parking brake and turn the key and it starts every time.
