The thing won't start. It turns over just fine, but won't start. The CHECK ENGINE light doesn't come on, the fuel pump isn't working (pressing on flap inside air flow meter on top of air filter housing with the ignition key on) and the heater/vent fan inside the cab isn't working. All the fuses check out as good (with an ohm meter) including the three under the hood and the 20A fuse for the heater/vent fan. Ignition switch is good. Fusible link is good. 12.55 volts from the battery. Fuel in tank. Ground from battery good. All turn signals, brake lights, head lights, dome lights, door buzzer, and other dash lights work.
When I bought the truck in 1985, I installed a kill switch that went to the EFI relay located in the fuse block to the left of the clutch pedal. When the switch was off, the CHECK ENGINE would be off and the truck wouldn't start. I've removed the switch and soldered the OEM wire back together. Still no CHECK ENGINE light.
The truck died from a stop sign after letting out the clutch. I noticed the CHECK ENGINE light was off. I eventually cranked the engine with the tranny in gear and the truck started. 1/4 mile later I parked it, finished my errand, and it started right up. I let out the clutch and it stopped running (CHECK ENGINE light off again). Nothing could bring the truck back to life. I recently replaced the clutch master cylinder with an OEM unit.
Any ideas?
