after swap car wouldn't start i got fuel, but no spark.
i changer the coil and the motor already had a new cap, rotor, plugs, and wires.
any ideas? maybe the ignitor? motor was running perfect b4 it can out of my friends 91 si.

thanks,
-chris

 

did you do any distributor rewiring? that could be a problem.

 

i didn't change the harness it came to me wired w/ a si harness already so wiring is correct.

 

check ur grounds

 

So long as your wiring is 100% correct the ignitor is your best bet. Or swap a known good dizzy for the one that came with the ZC, I've heard bad things about ZC dizzys *knock on wood*

 

[Q
UOTE=JCracer723]check ur grounds [/QUOTE]

 

what grounds? in the dizzy? or what i've got extra grounds on the motor.

 

had something similar...running SI motor was thrown in HF, no spark...didn't find out what it was, motor is now out of teh car

yea- even if the wiring was off you'd still get spark (I know from experience lol ) check the ignitor

yes there are grounds on the car. valve cover. the wirin harness has grounds. the starter has a ground.. check them all

 

What ECU?

Did you check the ECU fuse and hazzard fuse?

Is the car cranking over?

If the HF motor ran and the ZC is wired correctly, it should be no problem. I'd check fuses related to the ECU. I'd make sure no wires got pulled out of a plug or torn during the swap (it happens some times especially on plugs that people repinned where you can't really tell the wire is out). I'd triple check all of the grounds, connections, plugs, sensors, etc.

You know you're getting fuel, right?

It would be unusual for an ignitor to just go bad during a swap, but not impossible.

 

My buddy had the same prob a couple of weeks ago...dizzy-prob igniter-try a known working distrib on it...I used mine on his car and it fired right up.

 

whats it doing chris is it turning but not starting if so i bet that it is the ignitor mine just went out the other day it was instantaneous i was driving and bam nothing it really sucked because i was on a delivery.........if its not doing **** when you turn it on then check the grounds you have valve cover ground tranny ground and a ground that comes out of the harness that bolts to your thermostat housing make sure you got that one on or nothing will start............you see thats what you get for not letting me be there during your swap damn amatuers.........no really call me and ill see if i can figure it out i gots yo back fool............

 

also make sure the harness ground is connected on the thermostat housing. that's the ignition system ground.

 

yes i already said that make sure you check that one chris its very important and you see i do know what im talking about...........

 

ok i double checked the grounds and replaced the ignitor and still no start?

 

hf motors use 2 injectors dont they? and your using a si wiring harness, i dont know if the hf's are like the dx but even with the si harness you still have to convert the ecu harness to si
