I have been searching the internet and this site for hours right now and i cant find anything that is telling me wat is wrong. My wiring is all screwed up on my 91 dx with a b18c and i want to start all over. i did the dpfi-mpfi and it never fired i had spark but i dont think i was getting fuel into the cylinders. so wat r the exact wiring steps for a b18c into a DX. can i take an si harness and will it work? Thanx please help tired of searching for hours!!!

 

all i know is dont use an si engine harness i think you just add wires but dunno what

 

first off you are better retracing your work with the dx harness.. rather than using a si harness... double check each wiring you converted and make sure you didnt miss any steps... if you say your not get fuel in the engine.. i would recheck your fuel wiring...

what ecu you are you running?

 

if all else fails, call Ryan @ Rywire. Good guys

 

I am using a p28 sohc but am getting it chipped or am trying to buy a p72 would it make a huge difference that my car wouldnt start if i am using this ecu?
