just did a swap on a 94 prelude si took out the stock h23
put a jdm h22a from what it looks like a 97 lude

using a h23 wiring harness on the jdm>also h23 fuel rail> with h22 usmd injectors with usmd ecu

it will crank _but will not turn over ahhhhhhhhhhhh

can anybody help ---if so thanks

 

did you troubleshoot anything? did you check for spark?fuel?your timing?

 

FYI, crank = turn over.

Do you mean the motor cranks over, but doesn't start? You need to start your process of elimination...check spark, check fuel, check compression.

Always do the common sense diagnostics and post the results along with the problem you're having so we can better understand the issue and offer better advice.

Also...if the motor is a jdm h22a, you should be using a jdm p13 ecu. Always use the ecu made for the motor, unless of course you go with a chipped ecu and a tune.

Edit: You're using an obd-2 motor in an obd-1 car with an obd-1 harness? Or is the motor an obd-1 jdm h22a? If it's obd-1 and you're using the obd-1 h23a harness, what did you do with the distributor wiring? You can't just run the jdm h22a distributor on the h23a harness because the h23a harness is made for an external coil distributor when the h22a distributor is internal coil. You need to take the h23a harness external coil plug and put a fuse in it to connect the blue and yellow wires(I think those are the colors, you might want to search that one).

 

yeah i troubleshoot it

check engin code 16 fuel injectors

me and my buddy think that the fule injectors are not getting power cause we just replaced the fuel injectors

 

we used the h22a external coil distributor it came with

you said wire harness would the h22 fuel injectors that iam using work with the h23 wire harnass

 

What injectors are you using? Is the motor obd-1 or obd-2? Did you run any tests on the wiring to/from the injector resistor box? Did you alter any wiring? Are you using the usdm or jdm fuel pressure regulator?

EDIT: the jdm h22a distributor is internal coil.

Also, my knowledge lies with the obd-1 jdm h22a. If you're using an obd-2 motor, than I can't be much help. If using an obd-1 jdm h22a...the usdm h23a harness is fully compatible on the jdm obd-1 h22a motor...the only difference is there won't be any vtec solenoid/vtec pressure switch wiring, and you need to do the fuse mod in order to use the internal coil distributor.

 

i using h22 fuel injectors
the motor is obo2
i did run some test the only thing that came up was the jdm resistor box, the connectors one of the ports did not power when touched with the ome meter

 

it was the fuel injectors resistor box wires one of them stop geting power
so we hook it up to stright power

and its runs


so thanks for everybodys help i hope this info could help somebody else
