Need a diagram for wiring trying to trace wiring

Should be four ! 1 gray B+ power supply , 2 PPL - purple fuel level signal wire to the PCM - engine computer , 3 Black - ground for fuel pump motor . 4 Black with white trace - ground for fuel level sensor !

They are 2 ways to get this. An internet search using your year make and model car with the term fuel pump wiring or wiring diagram usually pulls up a collage of good diagrams. Or the autozone site has a help site at the bottom of its help page, There is a free part and a pay part, but free info will supply diagrams.

You need to buy or borrow a voltohm meter and check fuses for voltage and trace the voltage to the fuel pump.

You can't trace anything without wiring diagrams

What would you do,just poke away & hope you
find something?

Have to understand the system your working on

Have you tested out the fuel pump? check for plugged fuel filter?
plugged fuel lines to the fuel rail, injection pulse at the injectors? power to the fuel pump relay? grounds needed to make certain systems work must check those also. get a wiring diagram of the fuel supply system and back trace all the wiring and see if you have power and ground and signal.

TRY ANOTHER FUEL PUMP!!!!!!!!

CHECK FUSE + RELAY TO FUEL PUMP.IF THEY CHECK OUT GOOD.YOU HAVE PCM PROBLEMS. MAKE SURE PCM FUSE IS GOOD.YOU CAN BUY A HAYNES REPAIR MANUAL.IT HAS ALL OF YOUR ELECTRICAL DIAGRAMS.
