Ok, I got the motor in and everything else done. I am gettin spark (car fires on ether) but fuel wont get past the injectors. its in the fuel rail and everything. Put a known good set of injectors in and nothing. changed the fuel regulator and still nothing. The only thing its throwing a code for is O2 sensor because the prelude downpipe and cat. didnt come yet. I AM STUMPED!!! PLease help! thanks Zach

 

are you running a h22 ecu

 

something is telling me every thing is fine but the ecu isnt communicating to the injectors

 

majority of the time its the ECU..

 

ok we initially tried to start it with the p13 ecu and nothing, so we plugged the accord in and still the same. I am thinkning it has something to do with wiring. I plugged everything back in right so in theory the injectors should pulse. I am still using the resistor box and like I said I am only throwing a code a 1 (o2). If I unplug the resistor box wiring it throws code 16, which it should so....I don't know....keep the help coming!

 

what year is the car and the H22 ? if it's pre 97 then check the injector resistor box .

 

the motor is jdm h22 (is the casting year on the head like b series?) but yes it has a resistor box and i am wondering how you would check that if it doesn't throw a code for it. Could it be a ground somewhere? is there anything that could not be hooked up and make the injectors not pulse? I know there was that sensor that is hooked up in between the fpr and IM. (vacumm hoses) that we never hooked up. thanks Zach

 

what would all not make the fuel injectors work? I know the resistor box and main relay do but what else? I'm not throwing a code 16 tho?

 

ok I found something that might be a problem....in the main fuse box where the power goes into the fuse box there is another terminal for power right nerxt to it. I know something came out of there (the screw is loose) i dont know what goes there or where to look for whatever wire goes there. I don't know because I didnt take the motor out, I was just asked to wire it up. this problem is really bugging me!

 

ok i figured it out.......I can;t believe i forgot all about it after all the motor swaps i have done, the wiring harness ground that goes into the fuse was never hooked back up! thanks for all you help
