So I am trouble shooting a problem on my car that has been a problem for 14 years.
Symptoms are The car shuts down at random moments and wont start back up for a few days. just pops and backfires and then shuts down.
Things ive already tried.
Spring cleaning (GNTType.org)
Replacing fuel pump/tank (they were caked with rust), Cleaing fuel system, fuel filter, and new injectors
Installed a new fuel pressure regulator
replaced cci and timing modules with known good ones
Known good ECM and injector driver chip and Eprom chip
New caspers complete engine harness
New sesnsors, All caspers or AC delco. TPS IAT IAC, MAF, CPS, Cam sensor, O2 sensor,
I installed a fuel pressure gauge at the rail and I have fuel pressure even when car starts to sputter
ALL grounds are in place and are good.
When I installed the new cap. (caspers with led light) I noticed the light is on solid. and does not blink. So im wondering if it is going into batch fire mode and why. when I discontent the sender wire from cam sensor then it blinks, and it blinks while I crank the car, but when it starts, it goes solid. On a strange side note, I was trying random things to see if i could get it to stop, I unplugged the alternator excite wire, and the cam sensor began blinking. and battery voltage is at 11.8 volts. when i plug it in and the alternator starts charging, the cam sensor goes solid.
This car came to me from my uncle and he bought it in Canada 14 years ago. It has had this problem that long and no one has been able to enjoy the car since. ANY, ANY, help and ideas will be greatly appreciated. Thanks!!
