mpfi swap problem
just put the mpfi on my sohc zc but the car will not satrt it will just turn over abd you can smell the gas but that is about it.i have checked and recheck the wires but everything seems fine.any ideas what i should check. is the zc dizzy wired the same way as the si dizzy cause i could only fine wiring for the si dizzy and then the dohc zc but i got the sohc. used lots of the si conections so evrything should have matched up fine but i dont know beging to hate the mpfi swap.

Re: mpfi swap problem
i currently do not have spark. i replaced the cap and rotor befor i did the swap its weird i know i m getting fuel on all injectors and when i turn the car off from the run position to take the key out i get a large pop or explosion from within the motor so that why i would like to know the wiring all the wires matched up besides the 2 i ran to the dizzy but there are two of the same colored wire and when you alternate them you get an explsion on one setup then you switch them and get nothing im so confused and i am really sick of wiring now and would like to go for a drive

Re: mpfi swap problem
Do you get any codes (flashes) on the ECU?
Did you add the 2 extra wires to the Dizzy? I assume you are using a SI Dizzy which is highly recommended. On the SI, there are two white wires running to the dizzy, don't mix those two up. When I did my swap didn't get a spark until I replaced the ignition coil in the dizzy (looks like black plastic piece on top inside the dizzy, it is the same part as in a DPFI dizzy).

Re: mpfi swap problem
glad you figured it out
 How's the difference ? noticeable? I was gonna start my mpfi swap in 2 weeks on my next 2 days off, but now I gotta put a clutch in my g/fs crx instead >=/
