    There should be a fusable link on the engine firewall. You will see a block where there is a wire in and one or more out. There will be a strip of metal that is burnt in two. They may have changed the location on the 88 models. But it's a fusable link problem. It's a $5 fix.

    Two things to check. Do you have a ballast resistor in your ignition circuit? The resistor is bypassed in start mode, but is part of the circuit in the run mode. Another possibility would be the full pump relay. You could also go to www.off-road.com, and go to the jeep section. I use that board a lot for my 4x4 questions.

    You can buy a new fusable link at at any parts store. If you splice in your own make sure to use a wire 2 gauges smaller than the main wire.
