When i tern a corner my 93 jeep cherokee spot dies an then starts its self back up 2 or 3 times then dies an wont start could that be the rollover valve if so where might it be located?

Start with the basics, spark, fuel and air, take it from there

Try putting a timing light on it once you get it to crank and idle. Sounds like the timing is retarded too much. Advancing it should make it run better. Also check that you are getting proper fuel pressure to the engine.

If the check engine light does not light up on the dash when you turn on the ignition, at those times when your jeep doesn't want to start, then your main jeep ecm is in need of repair. The fuel pump relay will get energized only after that check engine light comes on. It's a known problem, especially with the first and second year production Grand Cherokees, 93 and 94.

have you tried to replace your fuel injectors or your spark plugsif not try checking your fuel injectors electric socketit couid be loose

It's time to change the neutral safety switch.

Clogged fuel filter and/or bad fuel pump

You need break booster what happen is when you tern the car of the vacuum leaks out when you start the car its take time to build the vacuum that's why it does not work at first time then its come back

start by tracing the wires back to the computer checking for breaks in the wire or corroded terminals

check the ignition coil pick up
