1986 pickup 22re will not warm start
i have been through most of the sensors by borrowing from a friends donor truck. I have traded out mass air flow, ignition module, coil, tps, coolant sensor, injector resistor, ecu/ecm whatever it’s called, cold start injector works that’s only way it starts, I have been through the wiring harness and looked for breaks, I have ohm tested everything I can think of, I have good spark and time well. Plug wires look good. It will run if I roll start it or put starter fluid in the throttle. Body.

i noid tested and found a bright flash from the cold start injector and very dim lights from the other 4. My thoughts are the injectors are not misting fuel enough to start but dumping enough fuel to run if I can get started.

I don’t know what to test next I am out of ideas. Would appreciate any input.

I also installed a new fuel pump and have checked the pressure.

I bought the pickup in no running condition and it had a badly warn camshaft so guessed that was the warm start issue. Replaced the cam and the rockers it runs real well until it will not start
