1997 jeep wrangler sport will turn over but won't start, done replaced the coil, distirbutor cap, relay switch, crankshaft postion sensor, & stator assembly from the distributor housing but it

The power control module sends signal to the fuel pump relay, it gets it's signal from the pick up coil in the distributor and the crankshaft position sensor. I'm having the same issues with my 94 Jeep Wrangler

So many of them things could have been checked to see if they was bad or needed to have been replaced. I see this a lot when someone goes to guessing on things and they can end up having a LOT of money invested and still not running.
My first guess since you've replaced all of them things is either you may have a ground issue or a bad PCM.
I would start by checking that you are getting power to everything that you are supposed to be getting power.

Then, I would check that you are getting grounds to everything too! You must have both in order for it all to work! If you are getting both and if you know how to check for both at all places, then I would eliminate the PCM.

If it turns out to be the PCM, try checking eBay.
Hope this helps.

Check to make sure the check engine light is coming on, on the dash, when you turn the ignition switch on. If it is not coming on, try leaving the ignition on for a few minutes to see if that light does come on and the jeep starts then. If so, then your ecu computer is in need of repair.

CHECK ASD RELAY THAT IS AUTOMATIC SHUTDOWN RELAY IN THE POWER DISTRIBUTION CENTER UNDER THE HOOD IN ENGINE COMPARTMENT.IF ASD RELAY GOOD PROBLEM COULD BE CAMSHAFT SENSOR IN THE DISTRIBUTOR.TO SAVE TIME AND MONEY HAVE JEEP SCANNED FOR CAMSHAFT SENSOR AND CRANKSHAFT SENSOR FAULTS.

Does it have a pick up coil under the distribtor cap if you dont know ask ato zone if your jeep has a pick up coil

Check coil, crank postion sensor and pickup coil inside the distributor. (most likely the cps or the coil)

No voltage to the coil or no spark coming outta of coil wire?If no voltag to at least 1 side of the coil(2 wires)..Check fuse 21 20 amp in the power distribution box under hoodright side of engine compartment.

I had the same problem some years ago until I changed the crankshaft position sensor. Unless the start switch is faulty. Check both of those

yea i would try replacing the pmc valve if its not your crankshaft

sometimes the ais(automatic idle speed) valve gets loaded with
carbon. its an easy fix. you have to remove the throttle body
invert it and you will see the ais chamber and look in and see if it is
built up with soot. carb cleaner should work.if you can remove
the valve for better cleaning. peterjai
