Ford p/u never let me down then one day it stalled ran ruff I could not keep it runnning. I have good spark and 40 psi at the injector rail.I have replaced, tps sensor fuel regulator, distributor and pip sensor, icm, ignition swith truck will run if you put gas down the snorkle. There is power at both terminals of the injectors. If I pull out the fuel relay and let it touch the contacts you can fell the injecters click and the truck started for a few seconds codes 22, 21, 24, 53, 54, 95 these codes were retrieved after we started it by pouring gas down the snorkle before that only 22and53 were there.

If you have good spark, fuel pressure, and the injectors are working (have power), you need to check to see if they are getting power when the engine is cranked. If you are getting a pulse, then you either are losing spark or fuel pressure. Have you checked for an injector pulse?

At injectors check voltage at RED wire 12V+?
Put test light on TAN or White wire crank does it flash?
