i have tried the cap, roter, coil, icm, main relay, and most fuses i can find. can anyone tell me where the icm fuse is? its a 91 crx hf with a jdm 1.6 zc. the moter is like brand new and the car usually runs great.please help!!!

 

in the fuse box on the passenger side shock tower.

 

sorry to burst your bubble..but theres a couple things you missed.. 1 is do you have fuel to each injector? an easy way to do this in my opinion is just take off the fuel rail with the injectors still attached to it and have someone crank just long enough to see if you have fuel 2. check for spark at every spark plug. 3. timing..make sure your timing marks are ligned up where they are supposed to be.. then theres simple things like grounds.. there should be 4 battery, thermostat housing, tranny, and starter.. theres also the starter, what is it doin when you crank can you hear it tryin to turn over? or is there nothing? if it clicks once then doesnt do it again, try tapping on the starter with a screwdriver and a hammer while someone cranks.. the spark plug wires, make sure they are in the right position on the cap.. make sure all your fuses are good and they are in the appropriate spot in the fuse boxes i dont think i left anything out.. good luck with it hope this helps

 

what is it labeled as?

 

ECU

 

i checked the grounds on the thermostat and battery. it dose try to turn but just dosent fire. i have checked for spark over and over again but dont seam to be getting any. im also sure the plugs are in the right order on the cap. if it was a fuel problem could it just happen all of a sudden or would there be warning signs first?

 

one time my car wouldnt start after driving 50 miles, and parking for five minutes, turned out to be the ground by the tranny, it was bolted up and everything, i just wiggled it and the car started right up.
this was after getting my clutch done like 2 weeks before
the symptoms was nothing happening at all when i crank

 

would your car turn over at all? my car turns over good and strong but it just wont fire up.

Lol, it may help you. i went through the same thing.

 

this kind of helps, but what ever happend with that guy? my roter spins so my belts not broken. i guess the timing could still be off though. ive tried all the same things he has and more and still nothing.

Lol, that guy was ME. it turned out to be the bearing in the dizzy shaft were bad so it caused the rotor shaft to overheat, thus melting the rotor's base, thus not allowing it to turn properly i guess. it looked fine though, which is why i overlooked it.

 

so did you have to replace the dizzy? last night i talked to this guy that told me 90-98 hondas are known for sensors in the dizzy goin bad. have you ever heard this? did you replace your roter before you found out what the ploblem was?

 

the sensor in the dizzy he its probaly talking about it the coil they go bad... ive had to repleace one in my dizzy beofre.

but it could be something else there is more than just a coil in the distributor, do you hvae a friends distributor that you can hook up to see if it starts?

 

ive replaced the coil and the icm the cap and the roter. checked all the grounds and fuses and replaced the main relay. does anyone know if a dizzy from a 90 crx si will work with my 91 1.6 zc?

 

yea the distributor will work

 

how are the spark plug wires? that coudl cause problems.

otherwise I sounds like a bad dizzy.

did you messs with any wiring on this car? like dizzy wiring or anthing?

 

no ive never done anything to the wiring.

 

so does anyone else have any ideas?

 

What engine harness are you using?

 

If the main relay is out would the car still be able to operate even if you push-start it?

 

Main Relay controls fuel home skillet also I believe it sends a signal to the ecu.

 

what do you mean by what engine harness? I bought a new main relay and that wasnt the problem. ive done every thing but replace the whole dizzy

 

im in the same spot you are
