Have a 2006 jeep 3.7 motor. Put cold air kit and throttle body spacer. now hard to start when cold and sometimes will stall at speed or sitting at stop light sometimes will restart sometime shave to set for 5-10 minutes before it will start.replaced starter,battery, tune up,crank sensor,cam sensor, still does it sometimes good for few days then may act crazy several times in row.can't trust to take out of town.
Get rid this vehicle to some pond and buy a new one.

Best thing to check is your fuel filter. After sitting for a little while, it will allow fuel through it but when you put a demand on the system, it cant supply enough and will sputter and die. Its easy to replace and very inexpensive. If it continues after that, you will at least know it was eliminated and can move from there.

I am going to assume that it will not run even if you push on the accelerator pedal?
Can you install or attach an old timing light to the spark plug wires, turn it one and try to start it. The light should flash with the engine running, but if it shuts off at time of engine die, and the engine is still spinning, you are losing spark, My suggestion is the cranks shaft sensor on bell housing.
Second, install a pressure gage on the test port on the fuel rail and watch it as you start the engine, fuel pressure should not drop as the engine dies, if it does, the pump is not working correctly. There are two modes of power to that pump, one to start and timed, for only a few seconds to prime the system, and one to run continuously. Find the wires going to the pump at the tank. Connect test light to those wires and watch what happens during crank and at stall, You should not have the pump shut off and the engine dies.
If you have spark, and fuel pump working, when did you last change the filter,,but I put that LAST.
It has to be one or the other of these.
Good Luck
SOURCE: Jeep Cherokee starting issue
On an intermittent start problem like this you may be having a starter solenoid issue or your wire on the starter from the key switch may be loose. Or you may have a corroded battery cable or the safety neutral switch may be going bad. Is it a automatic? If it were it would be the clutch safety switch going out. So do the simple things first. Clean cables like the first guy said if that does not fix it locate the starter and if you have jumper cables the next time it does it put the positive lead of the jumper cable on the Positive battery terminal and the other touch to the starter wire with the key in the run position where the big wire on the starter is, if you here it spin it means the starter motor is ok if it don't it is bad or the connection on the starter is loose. Also a bad battery cable could cause this from the battery to the starter next put a small wire into the end of the positive jumper cable and touch the S terminal on the starter if you here a solid clung it means the solenoid is good. So check the connections on the starter and tighten the starter bolts as they may have worked loose and don't have a good ground. So if you want more as stance just post on my question and I will hell p more and if this is more informative please rate
