No fire on a 1987 5.0 EFI

[Fryedaddy]

I have a 1987 5.0 EFI that won't fire.
This engine is in a custom '50 Ford truck.
I first determined the fuel pump was dead.
I replaced the fuel pump, gas cycles through and has 42 lbs of pressure.
Sprayed starting fluid into the intake and it tried to fire.
I have power to the injectors, but I was told when turning over the engine the test light should pulse, which it doesn't. It is just a constant light.
Checked fuses and they are all good.
Wondering about relays or maybe other issues.

Depending on what wiring you have swapped over to the truck, this may help.
