Default Ap1 Pgm-fi Relay Issues

Hello, I didn’t find any recent posts on this but if I missed something sorry. Anyways I’m having issues with my Pgm-fi relay. I’m getting no power to ecu or fuel pump and have no cel popping up so I bought a new relay still nothing, so I put a wire from pin 1 to pin 7 on the connector fuel pump turns on. Took a wire and put it from the pins that power the ecu ( don’t remember the pins) and the ecu has power so I think it’s the wire that triggers the relay or something. Could it be immobilizer or something cause the idiot that had the car before me put some sort of alarm system in and I pulled it out but it had this issue before I pulled it out so… any help would be great. Thanks

Did you check your fuses?
I don't remember specifically which fuse it is but I believe its a 7.5A fuse in the drivers footwell thats responsible for power to the ECU

I checked every fuse it’s good that’s the weird thing there’s no fuses that are blowing so…

I had this same thing happen to me with my AEM Infinity, turns out that I had a burned processor in my ECU. Not sure how helpful that might be to you since you are still on stock ECU, but what I would try is to switch your ECU out with a friends and see if the problem still persists. I don't know if the immobilizer would stop you from doing this but its worth a try?

I am running a Haltech Elite 1500. I tried plugging in the stock one and they have the same issue I think it’s unlikely that both ecu have the same issue. I figured out the fuel pump issue but the ecu power is still a problem I can get it to turn on but when I turn on ignition it cuts power to the ecu…

Maybe, I’m fully bypassing the pgmfi relay with switches, but I don’t know how to test the ignition. I’m going to try hot wiring the ignition to see if it works
