I have a 96 jeep cherokee no spark. I have replaced the spark plugs, Wires, coil, the whole distributer including cap&rotor still no spark. I was told to replace the plug to the coil I have done so. I used my wire tester to test the wires on the plug to the coil, the ground is solid the power wire has power to it when I first turn the key to the on position then with in a second or two or when I crank it over the power cuts out. Something I have noticed is when I first turn the key to the on position I here a click noise in the engine compartment possibly a relay or fuse? then the plug has power within a second or two or when I crank it over I here a second click and there is no more power. I only have power to the plug for that brief second or two any help would be great thanks! btoof83@gmail.com

What you describe is the symptoms of a bad CPS. See this thread.
Test the CPS.

Try using an OBD scanner. You could be throwing codes. It sounds like the CPS could be bad, but I'm not too familiar with the HO models. Anytime I have a starting issue on my Renny, the CPS is the first thing I check. HTH!!
