Fuel Injectors not pulsing after 94 Gsr Swap
1991 Crx Si
91 Crx Si engine harness
obd1 p28 chipped ecu, Check Engine Light on for o2 sensor
Rywire Jumper obd0 to obd1 Jumper harness and vtec subharness. they flipped pin d19 and d20 on the obd1 jumper clip so i fixed it.
94 B18c1 GsR motor came out of a running crx si
b16 j1 Tranny
This is my problem: my fuel injectors will not pulse. i checked for voltage and they get the amount that the battery, around 12v. i had an obd0 LS swap in it and it ran fine. i parked the car running. ive changed my main relay, changed and checked my fuses (maybe i missed one), checked timing, checked grounds. im using an obd0 b16 vtec dizzy. i was using a obd1 vtec dizzy but got rid of it because i had "bad" spark. my sensors are plugged in except a two wire small clip near the oil filter and pressure switch in the back. i deloomed my wire harness and everything looks and tests good. im using the stock injectors on the motor with obd0 clips. my whole harness is obd0 btw. it wants to start but just cranks. does anyone have any idea what else i could do? car doesnt start with starting fluid either. PLEASE I WANT THIS CAR RUNNING ALREADY. A FEW MONTH PROJECT TURNED INTO A NIGHTMARE.

Re: Fuel Injectors not pulsing after 94 Gsr Swap
You stated you're using the stock injectors on the motor. Given you said you were running OBD0 previously, does that mean you are using OBD0 injectors in conjunction with the P28 ECU? If so I believe that is your problem.

the injectors are obd1 not obd0. im not getting pulse on the inj. clip. i used a noid light to check it and i get nothing from it.

Re: Fuel Injectors not pulsing after 94 Gsr Swap
ive found out that obd0 inj clips wont fit into obd1 inj. so i must be running obd0 injectors. is this true?

If it all checks out I believe jlicrx just found your real problem.

i was using a obd1 dizzy before i swapped it to obd0 and the car still woudnt start. i wish i tested the injector clips to see if they pulsed.

Re: Fuel Injectors not pulsing after 94 Gsr Swap
I just realized I stated this completely wrong. What I meant is you can't run an obd1 injector if the wiring still includes the resistor box. It's a difference of peak/hold vs saturated style injectors, nothing to do with the ECU. Having said that, make sure you have them wired correctly.
