I have searched already!! Its a 92 si chassis with a jdm h22a in it. Well i have spark,fuel and compression and its still not doing anything, ive already changed out the ICM, dizzy, cap, rotor and plugs...ive checked the timing its good. what could it be? I heard that the main relay in these cars go bad could that be a cause? any input would be awesome! thanks alot.

 

are you sure your timing is right? what year h22? if 4th gen, did you add a resistor box for the injectors?

 

its a jdm h22 so im not sure what year but it is obd1 and my car is a 92 prelude and was already wired up with a resistor box.

 

is it turning over? i had problems like this befor. make sure all the grounds are in place.

 

some on po.com said it might be the main relay, any exp. this problem be4 and where exactly is it.

 

bump

 

You should check your timing again. As for the main relay i'm not sure in a Prelude, but check to either the right or left of the steering wheel.

 

the main relay keeps your fuel pump from priming, and you said you had fuel in your first post. How do you know you have fuel and spark?

 

You may want to go out and get a second set of spark plugs or clean the one's you have in and then have someone try starting the car while you turn the distributor. I thought I had my timing right on and the car wouldn't fire up and built up a lot of carbon on the plugs. Swapped them out (and cleaned the first set to have for a back up) and had my GF try starting it while I moved the distributor and it fired right up.

Hey it may not be the correct way of doing it but it fired up and I got the timing set dead on.

I am sure with the experience foating around here there may be some better advice but it's what I did.

 

^^^speedfreak77 i tried exactly what you had descirbed. I know i have fuel because my fuel pressure gauge on my rail is showing pressure when i try to turn the key, secondly i took out every plug 1 by 1 put it agaist the header and it got spark. im stumped i have no idea.

 

It sounds like the injectors may not be working correctly. Maybe like IHateJDM said it's a problem with the resistor box.

HMMMMMMMMMMMMMMMMMMMMMM?????????

 

Just because your getting fuel to the rail doesn't mean you're getting it to the cylinders.

hey bro i just had this exact problem check the crank positioning sensor by the dizzy i had spark and fuel and thought it was timing but it was cps but just dbl check your firing order too 1-3-4-2 1 being by the dizzy hit me back

Is it turning over at all?

Make sure your starter is working before you start pulling crap apart like this

 

yeah the starter will turn the engine over. As for the Crank sensor wouldnt i get a code where is it located?
