I have a 2001 jeep grand cherokee 6 cycl 4.0L. Car was running fine yes. night. got up this morning to start the car and it wouldnt start. took the starter and alternator to get tested both past with flying colors. i have gas in the car. I dont believe im getting spark to the plugs.. was wondering if anyone had any ideas on what it could be..

Don't just start replacing parts. There are several reasons that there could be no spark. And it's probably not the coils.
There is a distributor drive even though it's coil on plug. It houses the cam position sensor. There's just not a cap and wires. It is in the original position on the passenger side of the block. The ECM uses the crank position sensor, the cam position sensor and the automatic shut down relay to control the coils.
If all the coils are not tesing out, it is more likely the ECM, CPS, Cam position sensor, or ASD relay.
In the factory service manual, there is an extensive test for determining if the coils check out.
