I am working on a 90 civic dx that I put a 92 integra b18ls into BUT both cars are auto.. Does it fit? Not really but besides that it won't start. I got an OBD0 PR4 with no resistor box and the civic's stock wiring. I ran the two fuel injector wires (a5 and a7), two distributor wires(c1 and c2), and switch c1 to b10 and c2 to b12. The car will run on the stock PM5 ecu (on two cylinders) but will not run on either PR4 that I have, all ecu's are for autos. The injectors on the pr4 ecu are not grounding. I tried a different distributor and it didn't help anything. I runs great on starting fluid! But I just don't think that's a practical way to drive the car.

I checked the ground on the TSTAT housing, from the frame to the tranny and the valve cover to the radiator support. Everything checked fine. Main relay comes out fine.

Please help me.

bump for a non running car.

 

Can someone give me somethings to check on this car? obd-0 ecu, obd-1 motor obd-0 dizzy, converted stock harness to to mpfi and kept it obd-0, obd-1 injectors. No injector resistor box. Injectors not grounding, injectors getting 12 volt, car is getting spark. I have tried a different dizzy.

 

did you wire up the harness yourself or did you buy one? there are so many write-ups on doing b18 swaps into our ef civic/crx. was the integra motor running before you pulled it?

 

maybe you should try pr4 (obd0) injectors with a resistor box. this is how the ls motors came across the line. that might be your problem. not sure though, so don't quote me on that. anyone else?

 

I ran the wires myself. This isn't my first swap either. This motor ran fine when pulled. It runs, but only on the DPFI ecu and and thus only on two injectors. With a pr4 it won't run unless I use starting fluid.

 

This motor has its original obd-1 injectors in it. The motor is from a 92 integra.
