I recently installed a did a D15B swap on my 88 EF and I'm having issues with the fuel rail. I am using a PR3 and did the MPFI conversion myself. I have checked every freaking thing but im still only getting fuel from the #1 injector. I have fuel to the rail but only the #1 is shooting fuel. I need help before I blow my brains out. I have checked all my grounds, changed relays, checked fuel pump, filter, all of the usual suspects but nothing. HELP!!!!!!

 

That would be a wiring problem. I would recheck the MPFI swap that you did. What source did you use for that?

 

hondaswap, geosite and d-series. I resaerched all of them before i did it.

 

well either you fuel rail is clogged or the other injectors are not getting signal from the ecu. thats about all I can think of for getting fuel from one injector and not from the rest.

 

the motor is from a 93 civic i think i need a P28. would this make a difference? i used obd1 injectors and nothing. switched back to obd 0 still nothing. please help i'm about to blow this $%#^ up.

 

If you used a p28 then you would have to get a obd0 to obd1 conversion harness or rewire the dash harness. the obd injectors will not work try and look to see what voltage there should be at the injector harness. I would check for you when I get home but I just pulled my motor out last night.

 

so the pr3 would run the newr motor

 

What have you done about the resistor box? If you are OBDO and you go switching injectors with OBD1 you will fry things.....or vice versa.....Please be careful.

Are you OBD1? or OBDO? and what have you done with your resistor box?

This is very important.

 

the resistor box is still there and in use

 

You really might have fried them, check the ohms across the injector terminals. If the DMM reads 0 or nothing, inf., ofl., etc. you killed them. I forget the exacts but high impedance OBD0 injectors are around 10, low are around 3. You would use the resistor box with low impedance injectors. GL with your problem.

EDIT: opps... fixed OBD mistake
