I tried searching, but I was unable to find what I was looking for. I have a 91 CRX that has had a DOHC 1.5 lt ZC engine swapped into it. In addition to this it has a Turbonetics 14b turbo. I purchased this from an individual in a non running condition. The initial problem I found with it was the engage to starter sielenoid wire was not connected to the starter sielenoid. After replacing the battery cable ends and checking a few other connections I found no reason immediately not to try to start the vehicle. I was successful in getting it started and running within the first 2 hours after rolling it into my shop off the auto transport.
I had it under control at that point, I thought. I then dropped the panel down under the drivers compartment, and oh man oh man.... it was a fire hazard like I have not seen in a long time. I started to cut the wires loose that were jumping out this and that and all that crap. Majority of this stuff was to over ride the Main Relay peice of junk relay, but I also found that majority of the staring circuit fuses were blown. Once I got power back to the Main Relay (Matsuba RZ0063) I then expected to get the fuel pump back on, to no avail. The ECU light works, however, I still do not get power to the pump to fire the car. I know I am getting fire, I know I have air, I just need fuel. I can jump out the relay from the primary feed to the injectors and shoot a little fuel up to the injectors right off the relay. Of course once the fuel I have shot up there is consumed the engine starves and dies.
So, seems simple to just wire the fuel pump direct to the injector power or use that power with a 12 volt relay to power the pump off the switch or otherwise... that just wont work. It floods the thing out. I don't know if maybe there is something wired improperly on this harness or something I missed or what, but I do know that if I could control the fuel flow on this car it would be running and I could get to other issues with it. Any help you guys could provide would be very helpful. I am not a novice to working on engines by any means and wire is what I do for a living both networking and deep past history with car audio as well as vehicle wiring. I am just in a situation where I feel like I have missed something otherwise I am looking at a bad ECU.
