Question about 1992 Mitsubishi Montero
I have a 1992 Montero and have replaced the coil, rotor, transistor, plugs, wires. I checked all of the fuse with and Ohm meter and they are all good. The battery is in good and it cranks without hesitation. But I am not getting any spark to the plugs. Where do I turn next?
Have you verified that the engine IS turning the distributor by removing the distributor cap, and cranking the engine, seeing if the rotor that's mounted on the dist. shaft is rotating around? If it isn't turning while you crank the engine, then your timing belt may have broken.
Mitsubishi uses a rubber timing belt on this engine with a 60k replacement interval usually.
Remember, no rotation of the distributor shaft which is driven off the camshaft means no spark since the sensor inside the dist. won't function from a lack of movement.
If you DO have the rotor turning with a cranking engine, then make sure the coil is getting power. You may need to do an ohm check of the wires from the distributor to the engine ecu if nothing easy pops up during diagnoses.
Also make sure the coil and the ignition module that's mounted VERY near it are getting a good ground from the bracket that they're bolted to on top of the engine. Unbolt the bracket and use a wire brush to clean the underside of the bracket and the portion of the intake manifold if you're not sure. It may not help, but it's cheap insurance down the road since neglected grounds are the rule, not the exception on aging vehicles.
