2004 chevy 2500 HD.
Repairs for this problem = fuel filter assembly
My truck keeps dieing. Truck will pick right back up. Sometimes i have to restart. It
flashes battery not charging in display. A few months ago i had a battery boil and
replaced both with new ones. ECM really stumped on this and everyone i ask has
different ideas. From alternator to ECM. Got any ideas? If you can help i will tip you.

Answer: These problems do not sound like an ECM problem.
This sounds like a wiring problem somewhere.
Stalling without a check engine light or codes is usually a loss of power or ground
problem under the hood.
Be sure to check all grounds you can find.
Pull on wiring harnesses when it is running to see if you can get it to stall.
The battery problem may not be related, unless there are power wires shorted to
ground that are not protected by a fuse.

2004 GMC envoy 4.2 Inline 6 cylinder engine.
Battery replaced and vehicle was hooked up backwards.
GM tech = jk
question = This car has a draw on the battery and the only way to fix it is to take out about half of the
fuses in the rear fuse block. It doesn't matter which fuses i pull could the rear fuse panel be bad. The
battery was hooked wrong and it blew the 125 amp fuse that feeds the rear fuse block

GM Tech:
It is very possible that the short circuit caused damage inside the rear
fuse block. A short circuit that was enough to blow 125 amp, could surely
melt any part of the inside of the fuse block. May have also melted some
feed wires under the block.
I would remove it and look at the wires to see if one or more are shorted
together. If not, it may internal to the block.

Chevy 1996 S-10 pickup
Engine size = V6 4.3 Lt Vin X
GM Computer codes: Throttle position sensor.
Repairs for this problem: Alternator checked O.K.
Question: When I start vehicle, voltmeter on dash shows charge. Fuse # 4 blows out and when I measure across
battery terminal, I get battery voltage reading. Same result when I measure from alt to battery ground. Alt checks out
O.K when tested. My less than perfect manual lists tests under certain conditions to reveal if alternator is defective.
Condition remains the same. What would you recommend.

Answer: If the fuse only blows after the vehicle is started, you could
have an internal short inside the alternator. It could test fine, but still
be bad. Or, it could be slightly over charging or back feeding a
circuit to cause the overload. You should check the wiring from the
alternator, as there could be a pinched wire causing the short as
well. If all of the wiring checks out, there would be nothing left to do
but change the alternator and see if your problem is fixed. I'd be
sure to eliminate all other causes before spending the money on
such an expensive guess.
