I've seen threads for some similar issues, but not quite like this.
My Ranger is a 94, 4L, 2wd, manual, 199k miles.
When it's cool outside (mornings or evenings), my truck will start/idle/run/drive as it should. But when temps approach 90+, it will crank stong, but won't start. This happened a few summers ago for the first time, and has progressively been happening more frequently each summer, and now happens all the time.
When it starts, since it runs fine, I'm assuming the main components of my fuel & spark systems are ok, and my problem is some sensor somewhere that doesn't work right when it gets too hot. Is this a good assumption?
I tried getting the local O'Reilly guys to read codes, but they say their code reader will only pull codes if the Check Engine light is on. My CEL is off, but I heard there can be stored codes that don't trip the CEL??? If that's true & it's worth pulling codes, is there a sensor or vacuum hose I could disconnect that would make the CEL come on? Just so their code reader would work?
I'm hoping someone here has seen this before & might have some recommendations. Any advice is appreciated!
