Fuel pump/wiring issues......I just keep trying

[ftpiercecracker1]

Words cannot express the joyous feeling of finally solving a difficult electrical issue, so i'll just use emoticons. :banana:  :banana: :banana:  :rock on:  :jump:  :jump:  :jump:  :jump:  :jump:

Awesome what was it??

The EGR and Fuel pump resistor share an orange with black stripe wire. There are acutally two wires, but they are crimped together as they run side by side through the loom at the front of the engine bay. When i cut the EGR wires totally free of the harness i did not make enough of an effort to identify which wire went where. As it turns out, the ballast resistor wire runs to a large electrical plug above the group of black relays. The EGR wire is the one that goes to the relay, however this doesnt make sense because the particular relay it goes to is supposedly the a/c relay. :dunno:

 

ONE WIRE, caused the following. . .

 

pump would not prime

pump would not run with engine running

Fuel gauge read WAY over the full line at all times

TPS ohms were off the scale, don't ask me why.

 

 

 

Once i corrected the miss ran wire all of the above were remedied.

 

pump primes and runs beautifully

Fuel gauge AND low fuel light work

TPS readings are well below 1.00ohms, even on most sensitive scale (200)
