#460 of 768 2002 GMC Sierra - Won't start in morning by hwcape

Jul 06, 2010 (6:41 am)

My truck will not crank in the morning. I jump it in the morning, drive around all day and have no problems. After is sits overnight, the battery is dead and it won't crank. I had the battery and alternator checked at two different places and both times was told they are fine. Did anyone have similiar problem?

Hey Guys,
 
   I have an interesting problem, My truck will not start when I try to start it in the morning. I have to crank the motor for a good minute or two and consistently play with the throttle for it to start. After it starts it doesn't run right, and by that I mean it idles and if I WOT (wide open throttle) it revs up fine. But if I slowly open the throttle it miss-fires like mad and doesn't really run. When it reaches 190ish degrees and the O2 sensors kick in the problem completely dissapears. Now it didn't always do that I just recently replaced the Throttle Position Sensor and the MAF sensor, After Chevrolet told me my problem was and I quote "Sticky Valves" But before I ever replaced the TPS and MAF the truck just flat out miss-fired and was undrivable... I have thought about there being un-metered air getting in somewhere after the MAF, and I had left over upper intake and throttle body gaskets from when I had to replace the intake manifold gasket (coolant leak) so I went and replaced both of those and the problem still exists. I feel I have come a Long way from what the dealer told me and I think there is only one problem left... But I am Stumped. Any Ideas??? Thanks In Advance

check the fuse for the fuel pump, not the pump relay, if fuse is bad then the fuel pump is most likely out or going out

#463 of 768 crazy door locks by 240sparky

on my 2003 gmc 1500hd the door locks started unlocking while i,m driving, stopped, or shut off. key in or out. once the unlock you can hear it keep trying to unlock. may do it once or 10 times in a row. it is real random. I pulled both lock and unlock relays out as well as the fuse and it still happens.

Hi promotorsports,
 
I just notice the exact same problem with my 2004 GMC Sierra ExtendedCab on Friday (7/23/10). Today is Sunday (07/25/10) and the problem seems to be intermittent. I notice when the truck sits for a while (i.e. half hour/over night) the keyless entry will not work on the driver's door. I open the driver's door manually by insereting the key into the door lock and no courtesy light (readward on the door panel at the botton behind the map pocket) nor the dome light on the ceiling. When I insert the key into the ignition no chime sounds. When I turn the key to the on position (do not start engine), only the battery light comes on on the instrument cluster. Not the usual full lights system check during power on. No power to the windows, door locks, mirrors on the drivers door, yet the switches and courtesy light work on the passenger door work fine.
 
If I give it a few minutes and turn the ignition key off anf back on again twice or three times its like the system resets itself and everything returns to normal. Funny thing though, it rained here east of Toronto a lot over the past 3 days. Every time it rained the fault happened. Today it is dry and sunny - problem has not resurfaced.
 
Question for you - what was the source of you issue with your truck. What did you end up doing to fix it.
I would sincerely appreciate hearing back from you.
thanks...2004gmcsierra.

#465 of 768 05 GMC 2500hd electrical problems by trichie

Jul 26, 2010 (7:02 am)

This truck 05 GMC 2500hd has been an electrical nightmare since about 6 months after it was purchased new in Jan'05, latest is that after sitting for 10 days that the battery is totally dead. Multiple battery replacements the urging of the dealer still no change in the battery status after 10 days.
The most recent piece of the puzzle is with the 4 wheeler trailer (new wiring and lights) sitting on a rubber pad with the ground disconnected from the trailer, no ball contact, no safety chain contact , the trailer lights come on, both lights blinking with only one blinker, step on brakes and the lights go out acting like a poor ground, but there shouldn't be one.
Any help would be greatly appreciated.
 
     This was cut and pasted from another part to the site. Again any help will help, I have several more gray hairs because of this.

Hello Trichie,
I apologize that you are experiencing an issue with your vehicle. Can you please email me your VIN and current mileage so I can look into this further? Is the vehicle at the dealership currently or is it at your home with a dead battery? You can get my email by clicking on gmcustsvc. Thank you,

what exactly was your truck doing? mine will show the engine light and the heater on the passager side will blow hot air. Light goes out and tach acts up, signals quit, and the AC quits. sometimes the dash lights flicker. Sound familar?
