find the bad injector and just replace it. It could happen.

Progress update.


Found that the person who owned the car before me ran a power wire to the fuel pump and than to the radio fuse next to the brake pedal. Gosh there are some really stupid people out there who have no bussness under a hood of a car. ;-(

Anywho, now that this problem has been corrected I have no fuel pressure, OR power going to the fuel pump, with this said dose anyone have a wiring diagram of this, or know what i should check next.

Check the connector under the rear seat. The idiot previous owner of my car ran a wire around a burned-out pin there. Maybe your connector has burned out too?

You can find wiring diagrams if you read through the sticky threads in the Stuff You Need to Know forum.

The past owner may have been by-passing a short in the wiring.

When you "corrected" it you may have reconnected to the shorting wire.

Anyway, you should be checking for blown fuses that the relay is operating, that's the first thing to do with electrical problems.
