Will not start in Park, then will not start.

Either you got the wrong neutral safety switch or it is installed incorrectly

the switch is out of adjustment on its mount..loosen the mount bolts and readjust the switch..

This could be a faulty park/neutral safety switch. This is a switch that is used to determine whether the car is in park or neutral before allowing the car to start. This prevents the starter from turning while the transmission is engaged, which would cause the car to jolt forward. It's usually an easy fix, located on the side of the transmission. Remove the wiring harness, and carefully remove the switch, they tend to be brittle. You can replace it with a new one, or clean your old one (if it stayed intact). Just disassemble the switch, and clean all the old dirty grease off the contacts, and use a good electric grade lubricant. Good Luck!

sometimes the neutral safety switch goes out and thus it doesn't start... I had that go out in my 96 jeep cherokee sport 4x4... changed the fuel pump out and then found out... I had it changed so I don't know how to do that part.... anyway hope that helps

Your dealership can read the codes entered into your car's computer every time it malfunctions. Same problem as yours, however, also gets worse, back up lights won't work, sticks in park (in the gas stationing) (very embarrassing), will only run with foot on gas, etc. It was the "neutral safety switch". $500 fix but runs and starts perfectly all the time.

The jeep cherokee is famous for electrical problems check your neutral saftey switch.

There is a known problem with the 'neutral starting switch' that has occurred in two of our several Jeeps. Try starting it in neutral and park both and 'jiggle' the selector while you are doing it.

I have a jeep wrangler and to have it towed you are suppose to put the transverecase in neutral after you first depress brake pedal put trans in neutral then start engine shift auto trans into drive release brake pedal make sure there is no movement, shut engine off with key left in acc position shift auto trans into park, disconnect neg battery cable (damage can result in trans if shifted into park while transvere case is in neutral with engine running) you should refere to your owners manuel

Which engine? Has/does the vehicle randomly start and stop?

hope you can read it...(hint you can use WINDOWS built-in magnifier-see accessibility options in control panel) if not let me know...rate me FIXYA! thanks
