Hi jay, let me give you my 2 cents
You don't mention if the coil has been replaced or if your car runs normally after you get it started. The coils used on 3.9-4.0L engines crack due to heat and leak out current intermittently onto the block. Most of the times, when you test for spark at the leads it will be there but it will be weak and kind of blueish. This is not strong enough to work inside the combustion chamber, you need to verify a strong white spark capable of jumping a big gap or remove the coil from the car AND remove the brackets that hold the coil, then look for cracks.
