Does his ECU start your car or did you not try that yet?

just for clarification, your fuel pump is not priming when you key your car on using a prc ecu? if so, are you using e1 on your e-plug for fuel? e1 wont work for a prc. you have to use either e10 or e15. try it out you'll see.

What chassis?

I know with the EP3/DC5 chassis the PRC ecu doesnt have any immobilizor feature so the chassis wiring has to be modified to turn on the fuel pump.

If indeed you have a k-series motor in your car and are indeed using a k-series ecu then, YES, you DO have an E-plug. There is an A-plug (31 pin), a B-plug (24 pin), D-plug (17 pin), and an E-plug (31 pin) which all plug into the ECU. The E-plug is on the end.

The wire you "taped" for the fuel pump is most likely the "E-1" pin in the E-plug. For a PRC ECU the pin for fuel pump is E-10 (right below E-1 pin) on the E-plug. That is probably why your PRC ECU is not causing the fuel pump to prime when you key the car on.

Good point Fuat. What I stated above applies to 02-04 PRC ECUs. If he has a PRC with Kpro its more than likely is a 02-04 model.

thanks for the help guys..
