Some background- 89 Laredo with an A/T has crank/no start. The fuel pump doesn’t prime and there ‘s no spark. It’s killing me because it’s my kid’s daily and we haven’t been able to get it started since January. I think it started when he was trying to trace some wiring for the A/C. Not sure if he shorted something or what. In any case, i’ve refreshed all the grounds per Cruiser’s tips, checked and/or replaced the crank position sensor, MAP, TPS, coil and ICM. Nothing.
I was triple checking all the wiring to the relays. The B Latch relay has 12v to tge red wire, but nothing at either of the pink wires. I checked them at the relay and at the plug out from the PCM. Nothing at either end. Checked with key in run and while cranking. Does that mean the PCM isn’t powering them, and could that be our issue?
