I've got a 1982 Plymouth Reliant 2.6? with 116000 miles. It started out with no spark so I check the ignition module that was bad. So I replace it and the pickup coil. Started and ran fine for about 10 mins. Then died and never started again. It has very very very fire at then coil. I changed coil but still have problem. Module and pickup coil are testing good.

Make sure the neg wire on the coil isn't damaged. Also check wiring coming to it. I have seen wiring break down inside the insulation, so you can't see it. If you check for resistance, you will find there is too much.

Suggested Repair

Inspect the coil negative wire and the wiring feeding the coil for hidden internal damage. Measure resistance; excessive resistance indicates a failed wire that should be repaired or replaced.

Conversation Summary

The owner of a 1982 Plymouth Reliant reported no spark, replaced a bad ignition module and pickup coil, and then the engine ran about 10 minutes before dying. Spark at the coil remained very weak after the coil was replaced, while the module and pickup coil tested good. The expert advised checking the coil negative wire and incoming wiring for internal breakdown by measuring resistance.
