No fire on a 1987 5.0 EFI

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.
How bout some pics
