Default Re: Fuel pump relay problem

Do you have power at the injectors?

Is so, the injector relay in the PGM-FI Main Relay is turning on and has output when ign. switch is turned on.

The injector relay also supplies power to IGP1 and IGP2, and some of the engine valve/solenoid/sensors, so your problem must be between the output of the fuel injector relay and IGP1&2 at the ECU/ECM, [open circuit].

As mentioned, probably because of that cluster-**** of a wiring job, is the engine wiring the same?.

If it was me, I would be on PicknPulls site every day looking for 1996-2000 Honda Civics 96-97 Honda DelSol and getting new harnesses and only mod what you absolutely have to.

Right now I would probably try a bypass, test IGP1&2 at the ECU/ECM for a short to ground, if no short, run a temp. lead from the fuel injector relays output to IGP1&2 and see if that solves your problem, if it does, fallow IGP1&2 leads back from the ECU/ECM to where the connection problem is.

Blue butt connectors are not an acceptable way to connect anything except maybe a stereo definatly not ECU/ECM wiring, they are not even the correct gauge size for the wiring they are connecting, solder and shrink tubing is acceptable, repining is the best way, a proper jumper harness would also be acceptable but not as dependable as solder and shrink tube, [the less connection points on a lead the better]. 94

Ok. I am way over my head here. I really don't think that I could rewire my car. I have a hard enough time testing basic wires. I just don't trust myself. I wonder how much a shop would charge to do so.

Will the injectors have power with the key in the II position?

I just discovered my check engine light is on. I jumped the pin and the light will not flash at me. Does this mean code 0?

All the engine wires go underneath and I can't really see them. They all join one giant coil and goes to my firewall somewhere in the middle, can't really see

I just tested to see if my injectors are getting power and the are not. So it seems like the relay isn't working even though it passed the check I did on it. Can it still be bad even though it opens when it is supposed to? It never made sense to me that I replaced it and the car ran for half a day. So even if i put a new relay in there and it starts up then it will just have the same problems within hours. So not really sure what the hell is going on.

Hope you got something for me I really appreciate what you've been posting.
