Electrical 93 5.0 No Injector Pulse

[machinermac]

Just picked up a 93 5.0 because the seller was not a car guy and just wanted to drive it. I have run down as far as I understand the fuel system pulled the intake and checked fro 12v at each injector all good did continuity test from each injector ground back to the ecu plug all test good. None of the injector wires will flash a noid light. If I have the intake on and shoot starting fluid at it it does run (not perfectly) so I do have spark and timing seems right.

The next previous owner did some mods like a cam and suspension/frame stabilizers but the ECU and fuel look mostly stock. Looking for some direction on where to look to next before I start talking about a new ECU or just installing a standalone.

As of yet I cannot find a STI or loose cable that should be in that connector anywhere near the self test connector. There is a similar connector near the starter solenoid but its just black wires. I do have a reader but I dont want to fry a possibly good ecu connecting the wrong thing.

My guess is the PIP but need to pull codes first.
