DPFI to MPFI car wont start, HELP
 

Parts i use

92-95 intake mani w/inyectors and clips
92-95 dizzy
PR3 ecu

- First i do all the TPS, and other plugs work then
- Join 4 ground (Yel/blk) from the MPFI inyector clips with the 2 ground (Yel/blk) from the DPFI

- Match DPFI red with MPFI red and DPFI yellow with MPFI yellow from the inyectors.

- Connect the brown wire from the MPFI inyectors to A1
- Connect the blue wire from the MPFI inyectors to A3.

- I move pin C1(orange) over to pin B10, and move the wire from pin C2(white) over to pin B12 in the ECU

- Run wires from pins C1 (blu/grn) and C2(blu/yel) into the engine compartment and match them with same colors in the dizzy plug

- Match colors from the dizzy plug with OBD0 dizzy harnes wires

Conclusion, CAR WONT START ???

What i am doing wrong?

What's it not doing? No spark? No fuel? ECU error codes? Check engine light? [sarcasm]Battery dead? Starter dead?[/sarcasm] A friend and I had similar problem when we did a DPFI to MPFI. We couldn't get the bitch to idle correctly. It was rough getting it to start also.

So you're trying to use an obd0 pr3 ecu matched to an obd1 dizzy? No wonder it won't start. :P At least please tell me I'm wrong and it's an obd1 pr3. :3

Re: DPFI to MPFI car wont start, HELP
 

why not use an obd1 dizzy? and make sure your grounds are good. i did my first swap by myself and forgot about a ground and it turned out to be the problem.

try the thermostat ground, i missed that one when i did mine.

sounds like you need a obd0-obd1 harness or a Obd0 dizzy

Re: DPFI to MPFI car wont start, HELP
 

Because if he's running an obd0 ecu, the obd1 dizzy does not work.
Listen to the man. :y
