billwh87,
 
I'm truly sorry that the start-up concern you had back in February on your Sierra is still ongoing and that the dealership has not been able to duplicate it. If you wanted for us to create a new Service Request to continue looking into this (unsure if you had started one with Christina and if/when it had been closed), please send us your VIN and a brief recap as we have some new agents responding to inbound emails at socialmediagm.com
 
Sarah, GM Customer Service

Chalk up one more. Mine's a 2005 2500 Sierra. Been dealing with this for about 3 months now and resorted to keeping a 12" flat end screwdriver beside my drivers seat and a flashlight for night occurrences. For everyone with the same problem, this may be the best solution unless, like me, you're wanting to trade or sell your vehicle which I won't do until I figure this out. Anyway.......back to the screwdriver. Fortunately GM made the starter solenoid very accessible through the passenger side wheel well. Just turn the key on, walk over to the wheel well, and cross jump the starter solenoid. While this is at times entertaining to others who happen to be watching or riding with me, the luster has worn off at this point and it's just an annoying necessity. If this persists I will wire a switch direct to the solenoid and place it under the steering column so I don't have to exit the vehicle.
 
One thing that I don't believe I have seen mentioned on the numerous threads is that my truck ALWAYS starts cold. Which makes me believe it may be sensor that is being affected by temperature. And it does seem to happen more often with temps above 65 degrees, but is not isolated to that as it happens in sub 50 degree weather at times as well. Another thing is the security system light does not stay on as I have seen others mention. The only solution I have found outside cross jumping the solenoid is have patience....which I have little of. Sometimes wait 5 minutes and sometimes as long as 20 which makes me think it's temp related. But, here's one that seems to blow that theory. Whenever I try to start it immediately after driving it to try and replicate the problem (at a dealership for diagnostics for instance), it always starts. But, if it sits for a period of time (not enough to cool down though), it may replicate. I drove to a repair shop a few weeks ago, shut it down, and started it up about 7 - 10 times until I went in and told them I gave up trying to replicate it. As I went to leave it wouldn't start. But of course, after the tech got all the diagnostics hooked up, it was apparently long enough that it started right up for him. I may try to find out switch out the starter relay I saw mentioned in another post. I don't use the park brake, but someone mentioned that being next to it so maybe that's it. If that doesn't work I guess I'll wire up a switch direct to the solenoid this weekend and hope one of us figures this out by trial and error since it doesn't appear the GM engineers have any desire to figure it out given the many years of this phenomenon.....

I was told the same thing. I removed my key from the key chain and kept it alone in my right pocket for the past 9 months. It did not make a difference. The truck would not turnover several times during the time I had my key divorced from the rest of my keys.

I have had my truck not start when it is 20-90 degrees) when I first go out in the morning. But I have also had it not start when it has been warmed up and I run into a store for a few minutes. I simply keep turning the key on and off 30 seconds to 25 minutes, and eventually it starts. I haven't given up on getting it fixed, but it looks like there may be multiple reasons for this problem. It sure has helped keep the GM dealerships and spare parts divisions in business, replacing parts that weren't the real problem.

I also had remote start and had it removed. Dealership said this would solve the problem. Did not make any difference.

#456 of 492 1995 k1500 starting/running problems by bigbaddon

Dec 20, 2012 (6:54 am)

Okay..hopefully someone can guide me in the right direction. I have a 1995 K1500 with a 5.7L engine. Started it up to move truck and everything was great. Couple of days later, went out to start it and it ran very rough, finally stalled and could not get it started. First thing I did was to replace the plugs (extremely fouled-black sooty), wires and distributor cap. Truck was very hard to start, had to press gas all the way to the floor and it would finally start. Would run slow and very rough and after a few seconds would come up to speed. Took foot off gas and engine died, could not get restarted. (temperature?)
Pulled codes off OBT-1 by jumping pins on the connector and reading the ck eng light. Had on code that said something about voltage to fuel pump was low. Replaced water temperature sensor--no luck. Dropped tank, installed new sender and pump. Also installed new fuel lines and filter while I had everything apart. Same issue. Cleared codes, finally got engine started and rechecked codes..no codes. Oh yes...also checked timing.
Any ideas from anyone?

I have a 2002 GMC sierra 1500 2wd 4.3 and i drove it fine just the other day took a 200 mile trip less than a week ago. i went to fire it up the other day and it will crank but wont start and when i hook up the obd 2 scanner it says "no vehicle is present". i was wondering if anyone had any ideas possibly bad ground strap or something just looking for a good direction to start troubleshooting. and i already checked my fuel pump its cycles on key on power.

I am having a simular problem with my 2003 s-10 as well. Its been happening for months and it is randomly happening after traveling short distances (about 1-6 miles). Sometimes happens once/twice a week up to almost every time over the course of one day. It takes anywhere from 2 - 30 min to get it to start back up. This is my 3rd s-10 and the prev 2 never had an issue 91/98. I have disconnected the battery (checked good), checked the electrical wiring (all getting current), swapped out the relay switch and it did not have any benefit. i have tried to get it to fault with mechanics but it hasnt. The next thing I am going to try is hook up a wire directly to the starter and check the current when it faults to see if it is getting the voltage. There was one time it would not start for almost an hour and when ready to call a tow, it started up (after banging around the engine and banging the starter. Last thing I did was wiggle the wiring going in through the firewall and started.) Sometimes I can hold down the key to start for about 5 secs and the engine will start and sometimes it wont.
 
I am at a loss myself. I have searched on boards for months and still not been able to get a specific answer or find a specific problem. I am definitely at a loss myself, usually it is related to a direct issue but I cant figure it out.
 
P.s. while checking the wiring I did get it to fault and the currents were good.
