Run a compression test, and a cylinder leak down test to see what type of shape your engine is in. Also, check the wires going to the coil rail to make sure they aren't shorted. Sometimes on the 4.0 the coil rail wires rub on the back of the cylinder head and in turn can damage the wires. I'd also look there.
