Need help ecu
Hi guy/girls
got a problem, I've got a 54 ford f100 with a chevy 5.3 swap. Several weeks ago I had a starting issue. The engine would crank but not start. I noticed the I didn't hear the fuel pump relay not click. I turned the ignition ket on and off then the relay clicked and engine started up. Figured it was the relay. Today went to start and the same thing happened, crank but no start. Went out and got a new relay, didn't help. Checked for power at the plug and discovered no power at the plug. I have power at the ignition switch but no power from the ECU to the relay harness. Desperately looking for help.
thanks in advance.
