GMC Sierra 2500 QuestionsRefine by vehicle
I drove 45 miles the other day and then turned my truck off for about 10 minutes. I tried to turn the truck on and it tried to turnover once and didn't start, I turned the key to the start position about 3 or 4 more times and nothing happened, I waited a second and tried one more time and it started. I drove 60 miles and turned the truck off and it wouldn't start again. I had someone try to jump me off and nothing happened, so the guy suggested that I tap on the starter to see if that was the problem, I tapped on the starter a minute and it started. I drove another 60 miles and the same thing happened. I tried to tap on the starter this time and nothing happened, but I got a flathead screwdriver and touched it to the front of the starter and a piece of medal and it made the starter spark. After touching the starter a few times and it spark and tapping on it a few times the truck started, I drove 60 miles again and shut it off until the next morning. The same thing started to happen again and this time I had someone with jumper cables hooked up to my truck and I tapped on the starter several times and I made the starter spark with the flathead several times and it took about 30 minutes to start. I drove 60 miles and turned it off until today. I tried everything that I did before and nothing happened, I replaced the battery because it has messed up before and it was 7 years old. Still nothing, it won't even try to turn over. Any suggestions?
The front end is giving me trouble when I turn left it sounds almost like metal rubbing together and then when I go on a straight stretch its has a low rumble in the front end as well. Sometimes it's doesn't screech but always rumbles what could this be?
Truck has 100,000 miles on it. Just a long trips. When Im idling the gauge moves.
I changed the rear calipers on my truck and took precautions not to allow air into the system,but i bled the wheels many times and still the brake pedal goes almost to the floor. i have bled brakes on many vehicles but never had this problem.

Fuel pump is working fine.
The Green lamp light on the dash is on but no daytime lights. The head lights work fine when you turn them on.
My truck feels like it is in constant struggle to run...as if I'm running on less HP and low brakes
It runs great until you get to the speed you need then it studders and jump's.
OK, I have a 2000 GMC SIERRA 2500 6.0L V8. I just recently purchased this truck and have noticed the brakes being a little jumpy occasionally. Sometimes very bad, sometimes very little, and sometimes perfectly smooth. I pulled the wheels off and checked all of the rotors ( front and back ), and they seem to be worn down (1/16" MAX) (more like a 32nd). Anyways, they look like they have very little wear. I tried to use calipers to check for warping while spinning them and it seems that they are fine. (im no expert though). My problem with the whole situation is if my rotors were warped or worn I would expect my truck to jump everytime i brake, instead, it only jumps (or i notice it jumping the most) at lower speeds 35mph or less, and 3-4 times out of 10 it brakes perfectly smooth which leads me to think, something else could be going on. Has anyone ever heard of this or have any knowledge on this scenario? anything at all would be helpful. thanks
I need to replace the studs
after i refill with fluid i have pressure for a while then over night goes away i have to pump up the pressure on pedal
i have pressure once i refill resorvoir but it wint hold fluid over night
the leak is power steering fluid it does not leak brake fluid. abs lite comes on when the fluid is low.
When I activate my washers, fluid is forcibly blown out the top of the reservoir.
I do get fluid onto the windshield but am losing a ton of fluid out of the top of
the reservoir. How do I correct the issue?
Every now and then when I slow down at a stop light, the engine stalls. I can no longer trust that this truck can get me from point a to point b without stalling. Any ideas would be appreciated. If it's a short or loose ground, where would I begin to look?
the plug gap changes to .040 from .060 with stock and platinum plugs. What are the bet plugs to use in my 6.0 liter engine?
I just recently replaced the engine in my truck(6.0L) and the mechanic was very sloppy, and my 4wd indicator switches don't light up and in feel as though its locked in because it is hard to turn and the front drive shaft jumps when switching gears (P-D)and I had trans filter replaced too, what causes this and how can I fix it?
I have a 2000 GMC 2500 pickup with a 6.0 I go to engage the 4x4 in 4 hi or 4 low or auto 4WD and it switches over and just blinks and dose not go into 4WD I replaced the front axle actuator and the encoder motor and the switch panel and still have no different results

Can this problem affect the engine idle? Rough idle?

I am stuck in the mountains needing to go back to ms. should i trust it???
