MPFI blues...

so i'm almost a week into my MPFI swap.

that's right. a week.

everything is installed, all connections soldered and heat-shrunk (wire loomed and taped like o.e., too), but no start.

ecu throwing a code 4. TDC/CRANK/CYL sensor. go through the factory troubleshooting process, everything checks out - except the ecu. bad, bad ecu.

now i'm stuck trying to find another ecu - because i'm sure as hell not taking all this crap back off again.

no local salvage yards have any - but they can order one. for $150+, with no idea of when it would show up. nope, not going to do that. could go eBay route - in fact, i'm bidding on one now - but then i have to hope the new ecu is good, and i'm not getting screwed like last time.

argh.

just had to vent.

    I had the same problem. I ended up having the wrong year distributor. Once I chnaged that I had another problem, fuel injectors were spliced from the harness. To resolve this I wired the injectors stright from the ECU instead or wiring though the harness. After that it started right up.

    Hopefully this is some help.

    The CYP, Crank and TDC are all generally in the dizzy so as mrwagovan said, sounds like dizzy.

    yes, i've got the correct distributor. and the distributor and wiring are all o.k.

    the ecu does some other funky stuff, too. it's a bad ecu, trust me.
