Jeep's transfer case output is poor for lifts over 2-3 inches. A transfer case drop should have come with your 4 inch lift, but if not you should be able to purchase it from quadratec.com or 4wd.com. You shouldn't drop it much more than an inch, since engine will be rotated into your firewall, besides, transfer case drop reduces ground clearance. The spacers go between your frame and you transfer case skid plate. A transfer case shift linkage bracket is also required to maintain its alignment. Then if it starts making noise, the dealer has a TSB parts kit to fix that. A better solution is a Slip Yoke Eliminator and extended rear driveshaft, but you'd be looking at about $450 and a days worth of work. Good luck.

Hey Mudkicker,
Who ever thought of putting an electric fuel pump inside a tank of gas........
Check your other gauges for accuracy. They do that when a ground is loose.
Check the wiring from the fuel tank along the longitudinal frame for frays and shorts. Plugs are secured.
Under the hood, passenger side, check the fuel pump relay. Switch it with one of the others to test it.
Bring the vehicle to an auto parts store. Ask them to break out he code reader. Check for diag codes
Comment me back
Mike.
SOURCE: What does the auto shut off fuse do? 92 Jeep Wrangler.
The auto shutdown relay in your vehicle is controlled by the computer. If the computer does not see a signal from the crank or cam sensor, it will turn off power to the relay which in turn shuts off power to the fuel and ignition system. Unlike those in many passenger vehicles, it's not connected to an impact sensor. (as jeeps are off road vehicles as well as being transportation, if they had an impact sensor, they would be prone to shutdown when traveling over rough off road terrain)
The fuses to the relay are affected by shorting or overload of any components they serve, or by a problem with the relay itself.
