Question about 1996 Chevrolet Tahoe
Hello-My problem is sometimes my battery will die when my doors are left open (without dome lights being on) and if something is left plugged in 12v outlet overnight(ex. gps or satelite radio) The problem started one day when truck wouldn't start in the morning...jumped truck, started right up. Kept checking truck at work everything fine until truck sat for alittle time...jumped everything fine. Took battery to get checked, battery was fine. Truck was starting fine, until I was packing my truck up for a trip home, had the back barn doors open(maybe 30min) Truck wouldn't satrt. Charged battery truck started right up, but same thing happened on the return trip. I have turned the dome lights off and unplug everything at night...but if the doors stay open for a period of time, truck will not start. Truck wants to turn over, but after multipule times of trying battery just goes dead. Jump battery and still no luck getting engine to turn.I can also hear the fuel pump run for the first few seconds when ignition is turned on.HELP
Double check battery under load and verify it will hold for 10 seconds without dropping out under 10.5 volts , very possible there is a draw somewhere , check this by pulling fuses one by one with amp meter connected until you see maybe .3 volts .1 volt is normal

Try fittung a larger capacity battery this will help when you are parked for extended periods of time, but it does sound as if you have something draining the battery, try getting the alternater checked

I have had this problem on my 89 and my 94 gm trucks what it was is the pick up inside the distributor time to rebuild it (not the cap and rotor) the little thing inside with all the wire wrapped around something- copper wire with a clear coating on it the coating get hot and cracks causeing it to ground out when the vehicle warms up run ok until u shut it off then no start or runs rough

try bypassing the oil pressure switch on the back of the block behind the distributor, if there oil pressure switch goes bad it will do this. had one that drove me nuts trying to fix it then figured out I had to buy a book and low and behold thee it was 3 wire oil pressure switch you can't see between the engine and fire wall just behind the distributor and costs 8 bucks to buy new.
