Car is a 91 CRX Si with a 96 GSR swap. Motor is using OBD0 Injectors with the resistor box. New Fuel pump and New main relay, Cracked the line up at the fuel rail and there is fuel there. Spark is good in all 4, car will turn over with starter fluid but there is no power to the injector clips. One possibility is i think i may have plugged my wires back in wrong when i depinned the plug that connects on the drivers side, that leads to the resistor box. Other than that im stumped. If anyone has a diagram of the pinout for that plug it would be great. Or a suggestion. thanks! Edit: i also checked the fuses, which are all fine.

 

Is there voltage at terminal 8 in connector C313 on driver shock tower?

 

Yes there is.. but when i stuck the test light to it, it lit up, but i couldnt get a voltage reading from my meter... maybe i just had a bad ground[on the meter]?

 

I managed to do some testing today and i found that power is carrying through on that wire all the way to the plug for the resistor box, i hooked up a straight 12v power to the resistor box and and was not getting anything coming out. Is it possible for this device to have faulted?.. i didnt think something like this would go bad...

 

Are you measuring output voltage from the resistors with a multimeter?

 

Yes i am, and again after more tests im getting a resistance and voltage through the resistor box, and at all of the red wires for the injectors im getting a constant power supply. So now i am thinking it might be the ECU? I'm going to try to contact a friend to see if i can test out his computer on my car.

I also forgot to mention my cel comes on and stays on, i dont have anything to figure out the code though...

 

What voltage do you measure after the resistor? Post numbers for each injector.

 

Injector 1: rd/bl-11.73 brown-12.18
Injector 2: red-12.19 rd/bl-11.73
Injector 3: rd/bl-11.73 blue-12.18
Injector 4: rd/bl-11.73 yellow-12.18

Also just put 4 new spark plugs in

 

Are the injector clips installed in the correct firing order?

If you remove the fuel rail with the injectors and crank the engine, do any of the injectors spray fuel?

 

negative, no fuel coming out of the end of the injectors. Is it possible they could be clogged i dont think they have been used in a while..

 

It's possible that they are clogged, though it's also possible that the ECU in not providing ground for the voltage. Injector firing is ground controlled.

 

All the grounds are clean and down tight. I have a voltage at the clips now but my problem is there still not firing. My friend is telling me that OBD0 injectors should have a resistance of around 2.5 and im getting 1.8... would this make a difference? I cant find any information on the actual numbers.

 

1.5-2.5 Ohms is spec.

Sounds like the ECU is not providing ground to the injectors.

One at a time, ground each injector ground wire at the ECU connector. Does the injector click?

 

Yes they click... Im thinking somewhere along my wiring i have a bad connection to the ecu. Do you think i could just run manual wires myself from the harness and repin them in the ecu?

and in a recent test all 4 clips have power when the car is totally off... keys out of ignition...wtf..

edit: got the injectors spraying when power is connected and then grounded to the ecu ground... its a constant stream though. And like said above even when the car is completely off, im still getting power to all of the rd/blk wires on the clips.

 

You could, do younhave an extra harness laying around though?

 

i have a whole parts car lol. Pins are no problem.

 

What ECU?

 

UPDATE: One of the ground wires were faulty, the fuel pump primes and fuel is getting into the motor because every so often it will fire up for like a half of a second. The CEL is staying on it does not flash and turn off, the battery light is on as well... but the car will still not start and stay running.

just to be clear, the pump and the injectors seem to be priming but there not cycling..

 

Got the car running, i had my obd1 distributor plug wired incorrectly Duhh,. thanks for the help.
