All that means is the PCM doesn't think there is a problem. That does NOT necessarily imply that there isn't one.
Need to be able to read data. And see what the sensors are telling the PCM at cold start. Most code readers will also read data...... just having one at the right time is the tough part.
The check engine light only comes on if there is a problem effecting emissions. Most parts stores only use cheap generic code readers and if there's no cel, their reader won't show anything.
Would you suggest I try what bigarron said? This morning it was 15 degrees and it almost started right up, maybe turned over one or two extra times then normal. Or try looking at the temp sensor for the PCM, what am I looking for though?
you might just have some garbage gas. I started using mid-grade since this happened. This morning in Mid-michigan it was -3 degrees and my truck strated right up.
