S14 sr with obd1 harness. The car has no spark and the fuel pump won't pump or prime. I can jump the fuel pump from the relay. Everything is plugged in correctly. The ecu is seated properly with the harness plug. I have checked the ecu pins for power and it doesn't seem like all the pins that should be getting power are. I haven't traced the grounds from the ecu to make sure they are all good. The fuel pump is receiving power from the relay but not the receiving power from the ecu. It may be possible that the ecu is bad which is what I think may be causing the problem. It's a red WC ecu. I plugged in a red WC nistune ecu to see if it would prime the pump but it did not. I have searched this and found results but wanted to make sure if I can get any other help. It does have a hornet security system that I do think may be affected this issue. Let me know what you think.
