yesterday my truck just out of no where died on me in when i was at a red light. thought it was out of gas so we rolled it down to a station and put some in it... nothing still wont fire. then we checked to see if there was spark and there was none. i have heard that pre 96 4.3 motors dont have a Crankshaft Position Sensor. is the correct? my next move was going to look into the distributor and cap. anything else i should look into?
if u turn the key on and the lights on the dash dont come on but the engine turns over its the ignition switch not the key switch i had a 95 s10 4.3 4x4 manual trans that that happened to carried it to 2 different mechanics before they figured out what was wrong cost about 300 bucks back in 03 to fix it i think it had about a 140,000 on it when it went
I had similar problem on my 93 Jimmy, the problem was ignition module, I had spark, gas, but not fire.
In these models, that modul acts as crank sensor, no crank signal came to ecm, no signal from ecm to cpi !!
about $70 for that part !
