I installed a zc swap into a friends 90crx si and we try to start it and we are not getting any spark. Plus we noticed after a ½ an hour later that the downpipe was fluided with crazy gas. Any help will be great!!!!!!!!!

Check spark related systems. Obviously it's full of fuel because it's not burning.

Thanks. I mean the motor was running fine on the other crx like 8hours b4 the install.

is this a SOHC ZC or DOHC ZC?

honura

DOHC. Just gets spark like at random

couple of questions - this car is Si, correct? was the car it came out of also Si or was it HF? did you use the engine wiring harness that was on the engine in the other car?

honura

Sorry for the lack of info.

It came out of an HF and put into an si. I used the harness that was on the zc while in the hf. Umm I did not check to see if the Black/white or black/yellow is getting power. GOnna check tomm. But all the fuses are fine. Dahm I need to get this car running soon. B4 the event june.5th. Thanks for all the help guys!

you need to put the Si engine harness on it and do the wiring changes at the distributor and Cylinder Position Sensor - the HF harness will not work on the Si car - it will plug in, but most all of the wires in the connectors that plug into the chassis harness at the firewall are in different locations inside the connectors and some wires are even in different connectors

Ohhh OK. I noticed that it will only get one spark only the first time you crank the car. After that it gets no spark at all. I will have to check it out and see. Thanks gonna let him know to change the harness.

Well the car is started!!!!!!!! Changed the harness and everything was a go!!!!!!!!!!!!!!!!!!!!! Thanks guys!
