Hello,
I need help from the community again.
I have a 1997 Express 2500 van and I'm troubleshooting some fuel pump issues.
I have replaced the pump that was intermittent in it's operation and still have no fuel pumping or hear the sound of the pump working. I have replaced the fuel pressure relay.
Is there another fuse in the box under the hood?
My diagram on the box lid is messed up and I can't read it.
I noticed a section of the harness had been pinched against the frame and so I want to check those wires for the proper voltage.
I have 4 wires in the harness.
Black (largest wire gauge of the four)
Black/White
Purple
Tan or Yellow (I can't tell exactly)
Also, when I put in the previous pump about 2 years ago, immediately the fuel gauge would go back and forth when using the turn signal.
With this new pump the gauge fluctuates the same way.
Any help is appreciated!
Thanks,
Paul
