2001 GMC Sonoma 4.3l acts like battery is dead

I have a 2001 Sonoma. Sometimes the truck will just die and I will have no power. Not even the dome light will come on. When I try to restart it I get nothing not even a click. I have had the battery checked by 2 diffrent places both saying it is a good battery. If I unhook the battery for a few minutes and hook it back up the truck will start just fine. This may happen 2 or 3 times a week and then may go for a month without a problem. What am I missing here?

Maybe the main Ignition relay in your fuse box or on the firewall. Faulty relay can cause intermittent no-power situations.

2001 GMC Sonoma would not start, fuel pump would not kick on at all, and all the power was working (battery power) sprayed starter in and it will start, then dies, replaced the fuel filter thinking that...

Hello ,
The area you need to check ( check owners manual) is most likely this is two issues that could be. It could be your fuel pump relay , that is what triggers your fuel pump to work.Or your fuel pump itself. However first thing I would check is your fuel pump relay, which is normally square like fuse, check fuse box area, or sometimes it is under hood near firewall in a box, with other fuse relays. Thanks Mike

Want crank. Dash lights up a second and everything just dies. Doesn't even attempt to turn over.

sounds like you have a lose battery cable, if everything just goes dead at once..

Starting problems

With a voltmeter or test light can you check for power at the fuse block? There should be power to some of the fuses like ignition or radio, cigarette lighter. If not then check directly at battery. Some cars have fusible links between the battery and all loads, I don't know yours.

Battery Dead soon after service engine ligt came on

it sounds like you have a poor battery and a draw on your truck put a low amp clamp around the positive battery cable with the truck off and key removed from the truck for 10mins. then if you show more than 350mamps you have an excessive draw to find what is drawing the battery down start removing fuses starting with larger fuses until the amp clamp reads below 350mamps. then you know what circuit is causing the problem. check that the under hood light is turning off. common problem. good luck.

99 gmc sonoma starts sometimes and sometimes it doesn't

Check and clean your battery cables. Then, trace the wires from your battery to your starter. Make sure they are clean and secure. I believe this will fix your problem. If not, you may have a starter solenoid starting to fail.

Hope this helps and good luck!

Hey there JC

Could be the batterey, but I'm leaning toward cables or terminals. From your description its acting like the battery isn't there, even when you jump it.

  1. When you jumped it, did the other vehicles engine bog down at all?
  2. Do the head lights work?
  3. Is there any evidence of power? even the dome light?
First steps:
  • Test the voltage on your battery
  • Remove, clean and reattach battery terminals
  • Check the battery cables, good connection on both ends? no breaks, wear, anything odd?

Comment me back with your findings, we'll take it from there
