- Car has lost power and engine is running rougher.
- Autozone diagnosed that cylinder 2 wasn't firing.
- Removed #2 spark plug wire from ignition module, held close to module and no spark.
- Swapped #2 & #6 wires and #2 wire was okay.
- Cleaned and regapped #2 spark plug - didn't fix problem.
- Tested #2 plug by swapping #2 & #6 wires at ignition module and saw a spark from #2 engine cylinder to #6 ignition module.
- Measured primary & secondary resistance on ignition module and they were within specificaiton.
- Question1: what are possible causes of no spark from ignition coil for cylinder #2 and how can I troubleshoot? Could it be a sensor or computer problem?
- Question2: can I check ignition wires by measuring resistance with an ohm meter?
- Comments: spark plugs need to be replaced but I don't think this is the issue.
Thanks for your help, Tony
