1993 Jeep Grand Cherokee 6 cyl Four Wheel Drive Automatic 223000 miles
I have a 1993 Jeep Grand cherokee laredo 6cyl 4x4 auto trans. Before I tuned up this vehicle it would start fine sometimes and wont start other times and get no spark off of the coil. I replaced the cap, rotor, plug wires, plugs, coil and the crank position sensor. It started up the 3rd try and test drove it and the next morning it didnt start. I checked for spark off of the coil and no spark. Did not replace the modulator in the distributor. Also the fuel pump did not work but I tested the fuel pump and it works and replaced the relay switch and has power on the fuse box in the engine compartment. I tested the relay by removing the cap and turned the key to on pos. No spray off fuel hose. But when I moved the relay switch to make contact the pump worked but only when I did that. What could be the problem? Its like the power got cut off to the coil. And the fuel pump has power on the relay pluged into the fuse box but wont activate when the key turned on. Thanks for your help.
have the same problem?
