Using civic ecu no fuel pump
Using civic ecu no fuel pump
Hello, I have a civic ecu with k pro, at e1 and e7 there is battery voltage. The immobi is turned off any ideas. The engine is in a dc2.
The RSX ECU grounds the fuel pump to switch it on. Many (most?) swap wiring harness apply 12V to the fuel pump output, which then damages the ECU as soon as it tries to switch on the fuel pump.
The diagnosis is to put the ECU into a RSX and see if it works - if so, then it is not the ECU.
The solution, if the ECU fuel pump output is damaged, is to first fix the wiring, then replace the ECU.
