Yesterday I noticed a slight stumble when engine started several times during the day. I figured just an anomaly. Eventually at a start up, it did not start on first key turn. It would turn over but not start. I tried key again and it started. So I drove away about 500 feet to a stop light and then it stalled. Would not start after 3 key attempts. Opened hood, wiggled cps wiring. But nothing. I figured I needed a tow, so I pushed car backward 10 feet to get to a safer location. Tried it again and it started. Drove it home about 7 miles. It ran and idled fine at home, and started every time I shut it off for the next 45 minutes. I checked timing and was 10 tdc while in diagnostic mode. I fooled with and tried to get it to stall by bending the cps wires, coil pack harness, and wires out of igniter. Ran fine. Also. There were NO CODES. So, while running I pulled the larger connector on the igniter and of course it stalled and threw a code 14... which is what I expected to happen. I cleared the code and decided to install my spare known good and working igniter, and drove it this morning 50 miles to work no issues. The igniter I removed is the original one with 290k miles and I did the extra ground wire to chassis on it like 15 years ago. I also sprayed out the igniter and Coil pack harness connectors with electronic cleaner. I know there is a feedback loop between the igniter, coils and ecu, so I'm a little concerned that no code was thrown if indeed the igniter is failing. I was thinking fuel pump maybe as that is original as well, but I would think a fuel pump would cause a slow stall as pressure dropped. I had it just die. If it does it again I know how to trigger fuel pump, so can do that but any thoughts on my question about a failing igniter not throwing codes? Is that possible? Is it likely?
Why did I replace it? Well it's like 5 minutes to swap out and they way it stalled, then started a few minutes later made me think it might be going. Experience over the years tells me they can start to have issues, then usually get worse until they just fail completely (on other vehicles).
