I have had this problem with this car for about 2 months now. The car would sometimes crank but not start. However this time I haven't been able to get it started in a few days. It cranks strong and sounds good but doesn't start up. I checked the air filter and it was OK. It has a full tank of gas. The serpentine belt turns when cranking.. What else can I possibly do to find out and or fix the issue?

Thanks in advance

Replace the Ignition Control Module (ICM) and coil. Be sure to apply silicone heat transfer grease to the back of the new ICM.
