My 1996 Jeep Grand Cherokee Laredo will not turn over when started. It revs but does not start. I'm getting fuel in the line and have changed the distributor cap and button with no luck. Anyone have any ideas. Thank alot in advance.

Check audibly the fuel pump. It will run for 3 seconds when ignition is turned on, but engine not started. If it makes noise, you could check for pressue at the fuel rail. There is normally a schrader valve you can press. Tske care, fuel under pressure will come out when pump is ok.
if ok, check for eventual fault codes with scanner.
could be crank sensor.
ok, 2 things are happening, the most obvious is that you are low on fuel the pump spins faster, becauase there is no fuel to pressurise the lines
secondly, and more likely the fuel pump is failing, it is called cavitation. the pump pressurises the lines and there is enough fuel to keep the engine alive at idle, or at 5,000 revs. however, if the pump is failing it is only pumping enough to keep it at idle, and not enough to keep up with the demand of higher engine speeds.
soon enough, the pump will fail altogether, and and the engine will not start
The first thing I would do since you think it was flooded is to replace the sparkplugs, sometimes if a spark plug has been washed out with gas you cannot get it completely dried out. After you replace sparkplugs try to start the engine. If the engine starts I would still recommend that you change your oil because of fuel saturation. If your engine fails to start I would suspect that you have a bad crankshaft position sensor as it is known to give problems. The crankshaft position sensor is located on the top of the transmission bell housing on the drivers side.
Try gently tapping the starter motor with a hammer or bar. There may be a bad contact in the sollenoid or the starter motor brushes worn to their limit. Tapping may give you a tempory fix if the problem lies in the starter motor.
cj2176 is correct, we need a lttle more info. Sounds like it will need a new fuel pump or something related to it. Since it starts on starting fluid it has compression and air and spark, just no fuel. Fuel pumps can just stop working while driving, and if not working obviously will not start. No caodes will be set for a fuel pump not working. If it cranks but does not start have someone pound on the bottom of the fuel tank with a fist or small rubber mallet lightly (don't damage the tamk) while your cranking the engine. If it starts, the fuel pump module in the tank is bad.
Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)
its most likely the transmission i have a 96 jeep grand cherokee laredo 12 yrs old ..it went about 3 months ago.i would take off at normall speed and it would rev. to about 3,000 RPMS and then the gear would catch ,and give u wiplash.lol but then it got worse. it would be fine taking off then while i was driving ,,i would be going any speed but wen i got up to speed it would start reving high [the gear was sliping] and i had to get it rebult it was like $3'000 grand plus
