Ok, I'm installing a 2.5 ltr MPFI into a CJ5.
I am running into wiring issues with respect to the Jeep providing spark and fuel pump operation. I'm betting its due to not having the wiring straight for the Auto **** Down and fuel pump relay.
Anybody got any info on bypassing the ASD and fuel pump relays?
Engine and harness are out of a '92 Wrangler, the wiring harness for the CJ5 body is an EZWire kit. The engine does crank over, but there is no spark and the fuel pump does not prime/pump.
And yes, the Wrangler did work before I removed it from the other vehicle.
I tried calling Hesco to see if they could put together a 2.5 ltr harness like they do for the 4.0ltr, but that was a no-go.
I'm tempted to send the harness to someplace like Hotwire for them to rebuild. But this really can't be that difficult.
I really don't need the power distribution box from the Wrangler, so is there a way to bypass that, and then provide power to the PCM/ECU?
