run down: DC5R ITR k20a , in 02 civic coupe ex, mugen n1 ecu. fuel pump problems due to lack of wiring schematics for dc5r engine harnesses......... i tried the si ETM manuals and the rsx type s, 80% is matched up, but there are still problems. for example, if i hook up the civic ecu, the car starts but of course runs like crap. (keep in mind there is an immobilizer) if i hook up the jdm ecu the engine came with, the engine gets no fuel from fuel pump (why? i thought immobilizer is in ecu) if i hook up mugen ecu, same thing.......... HELP!
