turner-2000tj Posted January 5, 2012 Share Posted January 5, 2012 I recently picked up a 91 Comanche that was inthe middle of getting a 97 & up conversion. The only last major item not completed was the fule system. I'm using a TJ 15 gallon tank with an XJ pump assembly. When I first installed the pump and hooked it up it didnt work. When I started looking into why I noticed that the plug on the pump had been taken apart. I then took the plug aprt and sorted out the wires and thought I corrected it. Now when I turn the key the pump comes on, I can hear it priming and tehn shuts off after a couple secounds. BUT, its still not getting fuel. I removed the line from the pump and tuen the key to see if any fuel would come out, and it doesn't... I'm thinking I maybe have the wires wrong. does anyone have the wiring diagram for a 97 XJ fuel system? Any other ideas? Thanks is advance!

Boots Posted January 6, 2012 Share Posted January 6, 2012 Is it possible you have the polarity backwards on the pump so it's sucking air in instead of pumping fuel out? Just an idea.... :hmm: Link to comment Share on other sites More sharing options...
