Question about 2004 GMC Envoy
As I mentioned in my reply to an ignition problem did not start everything went dead, except the battery, which was fully charged. I slammed my hood down and for no explainable reason we were able to start the car. Yntil we stopped and while idling evrything went dead again. I repeated the slamming of the hood and voila it started again. Enough for me to the dealer we went. We return 1 1/2 hour later and were told that they found a problem with the throttle plate. They had to dismantle it and clean some build, which may have been part of the problem, secondly they discover that the ignition switch needed to be replaced, as it was not working properly. I said already another $200.00. They said it was a start and should have resolved the problem. I hope it has. I will keep u up to date.
HELLO, WISH I HAD U AROUND WHEN MINE WONT START,L.O.L U KNOW JUST BECAUSE THE BATTERY IS FULLY DOEST MEAN IT HAS ENOUGH CURRENT TO START YOUR CAR MULTIPLE TIMES! U SEE 12 VOLTS AND CRANKING POWER ARE TWO DIFFERENT THINGS! SEE YOUR ALTERNATOR IS USED TO KEPT THE BATTERY CHARGED SO IT CAN START YOUR CAR AFTER THE CAR STARTS THE ENTIRE ELECTRICAL SYSTEM IS POWERED BY THE ALTERNATOR NOT THE BATTERY,THE ONLY TIMES THE BATTERY IS USED IS TO START THE CAR AND SUPPLY POWER TO THE ELECTRICAL SYSTEM IF THE ENGINE SHUTS OFF! HAVE A LOAD TEST DONE ON YOUR BATTERY TO MAKE SURE ITS OK AND AT THE SAME TIME HAVE THEM DO A ALTERNATOR TEST AND MAKE SURE ITS OK, THEIR ARE A COUPLE OF NATIONAL AUTO SUPPLY STORES THAT WILL DO THIS TEST FREE AND WILL INSTALL A BATTERY IF FOUND BAD, AN ALTERNATOR COULD BE VERY MUCH DIFFERENT!(HOPE ITS NOT THAT) ONE THING U COULD DO YOUR SELF IS REMOVE BOTH BATTERY CABLES AND CLEAN THEM WITH A WIRE BRUSH,THE POST AND THE CABLES AND RE INSTALL GOOD AND TIGHT SO THEY CANT BE TURNED BY HAND. SO I HOPE THIS HELPS, BATTERY'S SHOULD BE THROUGHEN OUT EVER THREE YEARS,GOOD LUCK TO U.
