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
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!!
