'85 FI problem
The truck with the problem is a 85 F150 with a fuel injected 5.0. It has spark and 40PSI fuel pressure. It will run when you spray starting fluid into the intake. A noid lite hooked into the injector harness shows one injector pulse as the ignition switch is shut off, other wise there isn't any pulse to open the injectors. I have swapped the computer and it did not fix it. Please help. Thank you.

I would pull the codes on the computer. If you have any codes related to the dist module, then that would be why the injectors are not being fired. If it doesn't see any pulses from the module, it thinks the engine is not turning.
