First of all, the fuel pump is generally located in the fuel tank, not always though. Yours probably is, in did not research it. The fuel electric fuel pump turns on only when the ignition key switch is turned to the start position and then left on. A series of one or two relays along with a pressure monitor in the fuel rail delivery system may or not cycle it on and off depending on design. Enough of that. I suggest that you remove the spark plugs to see if they are oil/heavy cabon deposits.If so, professional attention is reguired. One more thing you could try is replacing the spark plug wires. the may be old/worn out/damage. This would give the engine spark a stronger spark,if worn and also replace the spark plugs.

Remove the battery connectors for 5 minutes and replace back afterward.

This will do the trick.

Thanks.

Have shop run an OHM test on your transmission sensors -- then have them replaced and rerun the OHM test. -- it's more than likely an input speed sensor that is not working properly and telling the jeep to go into "limp mode" hence your speed isn't changing but it can't read the actual speed.
