What ECU are you using? Did you change the engine harness? what distributor are you using. Reason Im asking is you need at least a PM5 or PM6 to run a MPFI swap. The distributor is the same way the DPFI distributor will not work since the crank angle sensor is in the dizzy on the MPFI. Get us some more info and we can help you with your prob
