More than likely you have a bad crank sensor or a bad EEC power relay (I think they still had those relays in '97 -- not sure though -- used to power up many of the engine control circuits)

No spark to spark plugs on 2000 4.0 liter sohc motor. coil pack, crank sensor?


Parts stores can test ignition module. You can check ignition fuse and tap on relay. Crank sensor is common failed part, but harder to test. If you know how to access it, you can test for continuity by back probing connector.

Yes you are heading in right right direction. Check to see if there is spark out of coil. Spark at coil means replace distributor or rotor. No spark at coil replace ignition module or crank sensor good luck. Oh yea crank sensor is cheaper i would try that first if there is spark out of coil.

easy way to check coil pack and hi tension cable, use a spark plug cut some of the threaded part to leave a 10 mm gap to the center electrode weld on a clamp , clip the clamp to earth attach the Ht cable to the plug, the spark must jump this 10 mm gap. Note don't run the engine longer then one minute as the mixture will be rich and heat up the converter

I get no spark at coil pack 3 & 6 on my 97


If you are positive that you have no spark than you either have a wiring problem to the computer or the computer has a bad "Driver" in it. Don't guess on this one. The ECM is very expensive. Get a pro to scan the computer and perform the necessary pin-point tests

Engine seems to miss fire while driving


check all the ignition components.sounds like when you get moisture,there is an issue.
coil packs,coil on plug and ignition modules are very moisture sensitive.there is a spray you can buy to help with that

Engine misfires


You didnt mention having changed the spark plug wires, so that is another item that could be culprit as well. As well, it could be a coil pack that is not working properly.

I cannot recall at the moment if that model year uses coil on plugs or if it uses coil packs. Either way, if it uses a coil on plug set up, take the one for the #3 cylinder and move it to say #4 or anyone of your choice and see if the misfire follows

If it uses coil packs, there is likely one coil pack that controls two cylinders. In that case just swap the coil pack with an adjacent one and see if the problem follows. Pay attention to where the spark plug wires go because it will be an issue if you get them mixed up. You just swap the coil packs around.

I would, however, start with the spark plug wires if you have not changed them already.
