i have a 91 civic hatchback dx with 91 crx hf engine and underdash wiring harnesses. I'm swapping a obd0 jdm b16a. I swapped both harnesses already, swapped the b16a already. Do I have to switch wires on any of the plugs on the engine harness? I cranked the car and it would just turn, but no startup. Was wondering if some plugs wires needed to be switch? Is there anything else that I needed to do? Please any inputs would be appreciated! Thanks.

 

anyone with any suggestions............

 

Not to be a dick but do you have the right ecu??

 

yeah. running it with a obd0 pw0 ecu.

 

ok, well other thing i could think of is either the timing is way off or you have the wrong firing order...

 

i was thinking the same thing. i will check that out. do you know if i need to switch any wires on any plugs? i appreciate your help.

 

you don't need to switch any wires as long as both the engine harness and the chassis harness are from the HF

are you getting a Check Engine Light? codes?
does the fuel pump turn on when you turn the ignition on?

 

^ true.

Do you have pics of your setup?
Make sure its on TDC and the dizzy and main relay are working.

 

timing is right fellas. dang, this is giving me a headache. i feel like giving up and selling it now. anything else i should check and do??????

 

check for spark and check for gas or get enginge choke like for dirt bikes and spray in the throttle body open then crank if it sarts its the gas

 

how many wires do you have on the DS shock tower?(big white plug)

 

Fuses...check em

 

have spark on the dizzy plugs. fuel pump primes, has gas at fuel rail. fuses are good. PS have the squre white plug, one big plug, and small plug. DS has one big plug and resistor box plug.

 

compression check?

 

compression is good in all cylinders...........timing is correct...have gas...spark...both hf crx engine and underdash harness...idk what else it wrong with it....maybe internal things????????????????HELP!!!!!!

 

You might just be that one lucky guy with a shitty ecu. Try switching with a buddy or something and see if theirs works.

 

the light on the ecu turns on when i'm getting ready to start the car...but will try another.....

 

Well same thing is happening to my friends car, and we have checked everything just like you have, the only conclusion we've come to now is that he had a shitty ecu. We still havent tried a new one yet though.

 

well try another ecu...will let you know......

 

thanks guys...finally found it was the freakin injectors...change them and fired right up...thanks alot fellas............
