ZC engine problems

[cteneyck]

i just put a zc sohc enging in my 89 civic dx and i cannot get it to fire.
i was told by the guy that sold me the engine that all i had to do was put my old intake, exhaust and distributor on the zc block and reconnect the wire harness and it would work fine. but i am not getting any spark from the distributor. plz help. thanks

not sure if the stock dx ecu will work or not that could be it.

Your problem is you are trying to run multipoint fuel injected motor(4 fuel injectors, with a wiring and harness and ecu designed to run a dual point fuel injected engine(two injectors). Do a search on here for mpfi and you should find some good info on how to convert your current wiring harness to run your zc. You will also need a new ecu. You can use any obd0 mpfi ecu ie 88-91 civic/crx si, 88-89 integra etc.

i am using the dpfi right now. that way i can keep it simple with the connections. the engine will turn over but there is no spark at the spark plugs nothing coming out of the distributor. all the connections should be the same. so i don't see whats the problem.

Ok my bad I didn't know you were using dpfi. Make sure all your grounds are good and then make sure all connections are tight and that the distributor is good.

just curious about something though. i was told that so long as i use intake man, exhaust man, and distributor that came off the old d15b2 then i shouldn't have a problem with getting the engine to start. is this true whats your recomendations. ps horse power isn't my main concern this is my sisters car and am just trying to get her back on the road...

thanks

distrib was bad and a relay went bad.

Good to hear it was something pretty simple.
