ok i been working on this swap for about a month now, and i just can't get to start.
so far this where I stand:
it turns over just fine
there is fuel going to the injectors
main relay its working
all grounds and fuses have been checked.
already switch the two white wires at the didtributor, no luck
there is NO SPARK at the plugs, there is a brand new ignitor, cap and rotor.
i have try differend coils and nothing...
I'm really frustrated now never thought that i'll say this but I'm starting to give up..

any help will be much apreciated.

 

what distributor are you using , ecu , and you know you have to do a mfpi swap right?

 

okay so you have allready switched over to w wires at the dizzy, but no luck there..hmmm

okay is the dizzy your using used or brand new? you said the motor turns over just fine.. but does it start and run with out killing itself????

if it turns over, but does not start and keep runnign fine you may have a bad distributor. that is what it sounds like.. if that is the case take the distributor out and look at the shaft on it that goes into the motor.. ususally if you can move that shaft side to side very easily (not turning it, but moving it side to side) chances are that distributor needs to be replaced... at least thats what it sounds like.. esp. if your not getting anything from it when switching to w wires.. there are two plugs on the dizzy. one is a 7 wire and the other is a 2 wire. the small one is the 2 wire make sure those are connect without them, the motor will not start ..also have you checked if your wiring is incorrect.. i hope this helps bro...

switch what wires at the dizzy? both 1.5l dpfi motors and zc motors have basically the same distributor without the CPS in em. you just plug the dizzy right in to the stock harness.

 

http://www.hmotorsonline.com/s...30020 anyreason why this zc is mpfi?

 

yes, the black top zc is mpfi, i know that. the dpfi dx motor is non sequential and has no cam positioning sensor in the dizzy. the black top zc also has no cam positioning sensor in the dizzy because it is moved the the exhaust cam. i, myself have a 90crx std and i also swapped in a blacktop zc. all i had to do was plug the stock dizzy wire plug into the new dizzy.

thanks for your respont.
let me be more clear.
yes I did the dpfi to mpfi convertion. I'm using a 89 integra ecu pg7 and I have the dizzy that came with the swap and I also have one from a 89 integra.

the car turns over it does not start whatsover I also have a code 6 on the ecu.

werid thing is that I remove the old dx motor because it was doing the same thing, but since i was going to put the jdm zc motor in I never bother to figure out what was wrong with it.

 

sounds to me like the ground at the thermostat housing, which is the ground for the ECU - make sure you have a good clean connection there
