I was getting ready to leave work. Went out to start my car and it wouldn't start. I tried spraying some starter fluid into the air filter compartment to see if it would start. No luck. Pulled one of the spark plug wires and grounded it, no spark. I replaced the coil, wires, cap, rotor and plugs. It turns over find, but I'm not getting anything. What else do I need to check.
Thanks

Do you recieve 12 Volts to the coil with the ignition on? Have you ever replaced the Crank Position Sensor? Do this too; cycle the ignition on-off 3 times and then on the 3rd leave it in the on position. The check engine light should flash at you. Count the number of flashes in groups of 2 separated by 3 second pauses. Apparently if this isn't the case for your jeep then it may spit out codes in the place of the digital odometer. If either of these are not available then it may be beneficial to retrieve an OBDII tester for the codes.
