I just swapped a h22 in to a 94 ex. It's a obd 2 motor that has been converted to obd1 using a obd1 ecu and dist. For injectors I used the stock obd2 injectors but wired the obd2 plugs to the obd1 harness. It turns over with slight sputter. It's getting spark and fuel but won't start. It seems like its so close but just won't engage.

I checked the timing by taking the dist. cap off and turning the crank to the point where the cam gears are pointing up. When I do that the rotor button points to #1 cylinder so I know timing is correct. Unless that is wrong?

Each sparkplug wire is firing. No fuses are blown. Its getting gas. Firing order is correct and double checked. Spark plugs are fine and gapped correct. I loosened the dist. and moved it to different positions while trying to start it, but nothing.

What am I missing? Any help would be greatky appreciated. Thanks in advance.

Do the OBD1 and OBD2 injectors use a resistor box?
I thought only one generation did.

The car has a resistor box. I'm not sure if the obd2 injectors use a resistor box.

 

bump for help.

 

obd2 injectors do not use a resitor box and they are saturated type injectors. Start off by getting the right injectors (obd1 lude's) then we can go from there.

What he said.

 

Aight I'm gonna bypass the resistor box and try that. Does the timing sound correct the way I described it?? thanks again.

 

when checking timing you can also take out the rubber plug on block and make sure flywheel timing mark is lined up to TDC as well when everything else is lined up. also when setting distributor to #1 make sure it is on compression stroke by checking for compression in #1 cylynder.

bypassing may not be enough. Your obd1 ecu is trying to activate a completely diffrent type of injector then what you have now.

 

ya, sounds like the injectors is the problem.

Yup.

I would go w/ OBD1 injectors.

 

go with obd1 injectors they are peak and hold. obd2 injector are saturated if you use the obd2 injector with the resistor pack then you will burn the ecu.
