Question about GMC Sierra 1500
Ok. I have a 2008 Sierra 4x4. Tried to unlock my truck with remote and no response. I manually unlock my car and tried starting it. I noticed gauges did not turn and No crank what so ever. I jump started it and the engine fired up. I let it run for about 10-15 mins and I turned off the engine. Just to see if my battery can somewhat turn my engine. No crank, click or anything. (Checked my battery gauge when it was running, it showed 12-14 v) thinking I guessed i killed my battery. I went and bought new battery. on my way back from store,Out of habit, I used the remote to unlock The Door And It worked. Started the truck, and everything was good. Couple of days later, I went out to go to work, same thing happened. Door won't unlock, can't start the engine. WTf is going on? I can't afford to bring this to the dealership right now, and I want to fix myself first before going there. Any suggestions where to start?

i had the same problem on my '92 Lesabre ltd. All you need to do it is get the rust off your battery cables, use the wire brush to scrub the contact surfaces. also use a wrench to tighten the bolt to the battery, take precaution as to not to tighten too much , it might beak the battery threads.

the intakes go bad on these engines....... they leak coolant in the cylinders and cause a hydro lock that causes the rods to bend making the piston skirt hit the crank......" clicking noise" theres a law suit in progress for this issue......... you can find info on the internet

A very common problem on the 99 S10 is a leaky fuel pressure regulator in the intake plenum.What happens is when the truck sits for a few hours or more the regulator leaks all of the fuel in the fuel injection system into the intake air plenum. This does 2 things, 1 it has no fuel pressure when starting and 2 it floods the air intake with raw fuel. Sometimes if you turn the key on wait 3 seconds then turn key off then turn key back on and just turn key to crank starter for a split second and wait 3 seconds.do this 3 times to repressurize fuel system then crank to start(you will hear fuel pump buzz each time you do this.also you may have leaky fuel injectors. Try to crank engine with the gas pedel to the floor. This will tell the computer to stop spraying fuel trhough the injectors and it will start. Joe ASE Master Tech
