Ignition System No-Start Check

Remove spark plug wire, and attach ignition tester to its end. Crank engine. If no spark, check a second spark plug wire in similar manner.
If spark resulted at either wire, ignition system is not at fault. Check fuel system, mechanical condition, and spark plugs. If no spark resulted at either wire, connect negative voltmeter lead to ground. In turn, touch positive lead to battery terminals of ignition coil and distributor, while cranking engine.
If voltage is below 7 volts, repair primary circuit (from battery terminals back to ignition switch and battery positive terminal. If voltage is above 7 volts, proceed to next step.
Turn ignition switch "OFF". Connect the ohmmeter leads to positive and negative terminals of ignition coil. Check for an open circuit in the coil. If open, replace ignition coil.
If ignition coil is not open, turn ignition switch "ON". Connect voltmeter negative lead to ground, and touch positive lead to ignition coil negative terminal. If voltage is below 5 volts, replace ignition coil.
If voltage is above 5 volts at negative terminal of coil, remove secondary wire from top of distributor. Attach ignition spark tester to end of coil wire. Crank engine and check for spark at tester.
If spark results, check distributor pick-up coil air gap. Clearance should be 0.012 - 0.020" (0.3 - 0.5 mm) minimum on one side. If OK, replace rotor with a new one.
If no spark results at coil wire, check air gap at distributor pick-up coil. Clearance should be 0.012 - 0.020" (0.3 - 0.5 mm) minimum on one side.
If gap is incorrect, adjust as necessary. If correct, replace control module (part of pick-up coil assembly). Repeat steps 1) through 5).
If spark results at tester, no-start problem has been corrected. If no spark results, original module was not defective. Install original module, and replace ignition coil. Again, repeat steps 1) through 5). Spark should result at tester.
