How do you test ignition coils on a Lincoln LS?

First, see if the each coil is getting the required voltage from the ignition switch (probably 12V). If they are, you can check the resistance of the coil with a simple volt meter. Should read minimal resistance. If the meter reads OL then the coil windings are open (defective/bad).

The 1991 did not have a CAM OR CRANKSHAFT SENSOR. If you have NO spark then the problem would be 1 of these. BAD ignition module, Hole burnt in the rotor, Bad pick-up coil, bad ignition coil, Coil wire. Check these things out. Start with the ignition module. That's the MOST common problem.


Why isn't there any spark to the distributor on a 1984 Chrysler Fifth Avenue?

No spark could be caused by several things: no voltage to the coil or ignition system; a bad coil; a bad ignition system; bad pickup coil(s) in the distributor; a bad coil wire; or more serious engine problems such as a broke camshaft or camshaft timing chain. If your distributor is fine and the coil is good as well as the ignition system is in working order, you might check the computer on the side of the air cleaner.
