Was driving down the road The other day and my vehicle listed above Cherokee quit running. And now just cranks and doesn't start. Have replaced crankshaft sensor. Starter and battery good and have not been able to figure out why it wont start.

Good morning,

You need a spark, fuel, and compression for it to run.

Can you hear the fuel pump run with the key on? You will need to check for fuel pressure to be sure the pump is working.

Spark, when you crank the engine, does the tachometer move up a little? that will tell me if the crank sensor is sending a signal to the ECM.

Compression. This is a test to see if the engine is mechanically sound.
