I have a K20 swap in my DA Integra, I used a 96 Integra chassis harness. Now here's my question, I plugged the USDM PRB ECU in to see if my gauge lights were working and the fuel pump primed. I didn't think it was supposed to prime with the immobilizer? I then tried a K20A3 EP3 ECU and it primed the pump as well, both clicked off like a normal car. Is the fuel pump supposed to prime with a USDM non modified ECU? Thanks in advance.

 

What kind of engine management are you using? Honestly if you still have the immobilizer enabled then I don't believe that it would turn over. The fuel pump may prime, but the ignition may be disabled. Have you actually started it yet?

 

I'm going to be using KPro, but I just put the USDM ECU in to make sure my indicator lights functioned. I just didn't know if the fuel pump was suppsed to prime still with the immobilizer? I cranks over, but I haven't actually tried to start it.

 

any other?

 

Well, the immobilizer is not affecting the fuel pump, but doesn;t let the injectors and coils start the car.

 

Yea, found that out, people were telling me the fuel pump wasn't supposed to prime...well it is just like it's supposed to.
