2000 XJ Won't Start

A story first, sorry. Went kayaking Sunday and left the XJ parked by the creek with a half tank of gas. Paddled downstream a couple of hours to the wife's 98 ZJ then came back to pick up the XJ. Fuel gauge was on empty and it wouldn't start. I assumed some bastard siphoned my tank. Got some gas and put about 2 gals in - still wouldn't start and the fuel gauge didn't appear to move. The XJ was not level so I pushed it to a level spot, banged on the bottom of the fuel tank to wake up the fuel pump - still nothing. I did not hear the fuel pump engage when I turned the key. It was getting dark so I got it towed. That's the story so far, any ideas?? Thanks Steve

Is it possible the CPS crapped out? Would that cause a no power to the fuel pump condition? A little help...?

Fuel pump wiring pulled, fuse... relay... pump.. in that order. Sometimes thieves use a battery to pump out fuel if they can't get the cap off. Takes a while though.

I'd bypass the fuel pump relay and see if the pump kicks on.

note: without a schematic I can't tell you exactly how but on most fuel pump relays you run a wire between sockets 7 and 9 (sometimes called 30 and 87).. Use the service book to confirm which ones.. :)

Thanks Doug and Bill for the responses. No one siphoned my gas, it *was* the CPS. I'm back on the road.

That blasted CPS has got to be the #1 no-start fault on the 93 and up Jeeps. Either that or darn close.

Thanks for letting us know.

Could the CPS also cause hot start problems w/XJ's (91)?

Yes, the plug and socket for it's connection sits close to the manifold on some and heat affects all of them. They are low power computer pins and get corroded when old, but still can look ok. They can be cleaned with a spray contact cleaner electronics shops sell or even WD40 in a pinch will work.
