starting trouble with my YJ
it started when i broke down last week.I was on my way to work and it acted like i ran out of gas (have full tank) and would not start back up.After i was towed home i tried starting it and it would just crankover.When i would leave the key in the on position the auto shut down relay and fuel pump relay would start clicking.When they stopped fuel presure would build up and it was able to start.Now it just turns over relays wont click. I just did a tune up and replaced the coil.Oil presure gauge would increase with rpm's.I checked everything i could think of.Fues's ,swaped relays,pulled fuel pump out,checked power to fuel pump.changed ignition switch,looked for bare wires,fuesable links.ANd im not able to get any codes because the check engine light doesnt allways work.The only other thing i diddnt check for is a short in the stearing collumn. anyone have any sugestions "please" c

Didn't you just tell the fuel pump is not working?

Yup, having just been through this on a '95 YJ...change the fuel pump.
Got the pump and strainer through Car Quest for $107 including tax.
Everyone else wanted to sell the whole tank unit, gauge sender and all.

Re: starting trouble with my YJ
My guess is you have a fuel injected 4.0 YJ with a dead CPS or a broken
body ground strap.
You could have a whole pile of different engines in there depending on
what year it is and they all have their quirks so letting us know what
'kind' of YJ might increase your odds of a fix.
If you have the 4.0, then the CPS connection is on top of the manifold
at the back and the CPS is on the top drivers side bell housing.
Usually it's just a dirty plug that a clean with spray contact cleaner
will fix.
The body ground could be a mesh cable from the rear of the head to the
firewall or from the battery to the firewall or fender. If this is
ratty, only a full charge on the battery will allow power to pass. Now
that you have worn down the battery, it can't pass a bad connection so
nothing clicks anymore.
