I have replaced plugs, wires, cap and rotor, module on distributor, coil and capacitor on coil with no improvement.
when I start the truck. It starts easily with key in the start position. As soon as I let the key go to the run position it quits.
once in a while the truck starts like new and runs for about 15 min. Then back to where it will start. But not run.
i thought about the resistor(22K OHM) in the run circuit, but discounted that because the truck does run once in a while.
any help would be appreciated.
thank you.
