Ford has substantially altered their 1978-86 electronic ignition test
procedure. Due to the sensitive nature of the system and the complexity
of the test procedures, it is recommended that you refer to your dealer
if you suspect a problem in your 1978-86 electronic ignition system.
The system can, of course, be tested by substituting known good
components (module, stator, etc.)
This system, which at first appears to be extremely complicated, is actually quite simple to diagnose and repair. Diagnosis does, however, require the use of a voltmeter and an ohmmeter. You will also need several jumper wires with both blade ends and alligator clips.
The symptoms of a defective component within the solid state system are exactly the same as those you would encounter in a conventional system. Some of these symptoms are:
- Hard or no starting - Rough idle - Poor fuel economy - Engine misses while under load or while accelerating
If you suspect a problem in your ignition system, first perform a spark intensity test to pinpoint the problem. Using insulated pliers, hold the end of one of the spark plug leads about 1 / 2 inch; (12.7mm) away from the engine block or other good ground, and crank the engine. If you have a nice, fat spark, then your problem is not in the ignition system. If you have no spark or a very weak spark, then proceed to the following tests.
Tell if you are talking about this ignition system...
Hope this help.
