The one I have in my basement will work for you.

$20 plus S&H?

The 94+ MX-3 RS was the only one with that exact motor.

Rule #1 of Pick'n'Pull's is never trust the employees to know ANYTHING specific about cars.

Seriously, trust us.

Yes, 94 was a bastard child, and OBDII started in 95.

Dear lord. I remember this.

Poor guy, thats a horrible mess.

So you put a new 96 harness into the 96 car with a 96 ECM, and no go?


No fuel pump kickining in means that you're not getting the signals from the disty. Check between your harnesses that the distributor pins are correct, that is, each pin on the disty harness traces back to the same pin on the ECM between the harnesses.... follow?

Aside from that, if your new harness is indeed good, its just a matter of tracing it all back... start with looking for 12v and ground at the disty.

Did you ground the ECM properly? This is important, or you might cook it.
