Fuel Pump Schematic/Wiring
Re: Fuel Pump Schematic/Wiring
Sorry, its a 95 motor in a 94 body. The wireing is slightly different. I put the motor in and have everything connected, but the fuel pump wont prime when i turn the key. I tryed jumping the fuel pump relay to no avail aswell as hooking a test light to the positive battery terminal and the other side to the fuel pump prime connector, it lights up. Meaning that the prime connector is grounded.(don't know if its suppose to be) Im thinking something hasto be grounded wrong but i don't see what. I have power to everything.
Re: Fuel Pump Schematic/Wiring
It's a good idea to give all the info you can up front. It saves time and lets you get responses that are more meaningful. You should also make a short signature with info about your car.
Do you have the Pass-Key stuff connected?

Re: Fuel Pump Schematic/Wiring
I pulled the column down to install the clutch pedal's but i didnt disconnect anything. So i would assume everything is still connected. Currently the problems are no fuel or spark. I hooked a DVOM to the 4 wires that go to the opti, two were reading .2xx, the other one was like .008 and the last one was reading 12 volts! I know 2 wires are for a 5 volt reference and the other two shouldint be reading like that. I hooked a spark plug to a disconnected plug wire and cranked the car, no spark. Then the fuel pump dosint prime when the key is turned to the on position. I broke open the fuel pump relay and when i manually close it the fuel pump kicks on.(i have another relay)
So i talked to my old high school auto teacher and he told me to switch the wireing harnesse's. The motor and wireing harness now are from a 95, my car is a 94. He said hook up the 94 wireing harness to the 95 motor. I don't think that will have anything to do with it. It looks like a anti theft problem but i never messed with the system!
The only difference between the two are the 95 wireing harness has http://shbox.com/1/harness4.jpg that C105 wire harness and my 94 dosint. So theirs no hook-up for it.
Sorry this is so long. I refuse to sleep until this is done! I wouldint of made it this far without you guys!

Re: Fuel Pump Schematic/Wiring
Well it ended up being the wireing harness. Put the original one in and the **** fired right up. Thanks to everyone here. I honestly wouldint of been able to pull it off without all the help ive gotten.
