1987 silverado fuelly won't start
I have a 1987 4.3l auto chev pickup here. It won't start...it began as an intermitent problem and now it just won't go.
There is lots of spark, so I went to fuel. When I ran power to the pump in the tank, it worked, so I tested the relay, it's good, so I started with wiring
schematics. Traced back to the ECM. According to Mitchel1's schematics, the wires that are to power the fuel pump relay have no power coming out. So, i tried a different ECM. No luck. I think I'm missing something, but what???
