    Not very familiar with the older Cherokee - any check engine lights?

    Do you have something like this that you can test for spark with?

    My 1990 cherokee didn't have a check engine light or means to plug up a code reader. IF I remember correctly there were limited codes you could get by turning the key and counting a flash in the dash. Sorry my memorably isn't better.

    Wash it running ok prior to the coil change?

    Spark, fuel and compression you need all three. You have to find out which one your missing. Pull out a spark plug and hold it against the engine while a buddy tries to start the jeep. do you see a spark, Yes/No. If you have a spark have a buddy try to start the Jeep while you spray starting fluid into the air cleaner or carb. Did it try to start, if so you have a fuel delivery problem. Check as to why your not getting fuel. If it didn't try to start check and log the compression in each cylinder.
