dead battery

[moparhed]

seems the fuel pump cycles for no apparent reason with no key in ignition over a 2 day period the battery is pretty much dead Truck starts and runs fine also the alternator is working normal

Yes, the fuel pump relay has a 99% chance of being the culprit. I think it is under the power dist. box in a 92....
