Coolant temp sensor determines fuel mixture at start - if it's hot, less is needed, if it's cold, the mixture is enriched. When the sensor goes bad, it tends to guess towards the hot side, which means not enough fuel to fire correctly.surfbug1 wrote: 24 Sep 2023, 20:02GinPLUS wrote: 16 Jan 2019, 06:08 This ended up being the coolant temp sensor but at least I learned a few new things along the way.
hi
I'm having extended crank times
just curious, how does the coolant temp sensor come into play here, and why did this fix the issue?

In my experience they first fritz at a particular temp and then full on fail. If that's the case, you'll find out when the season changes most likely, or smack dab in the middle of winter.surfbug1 wrote: 03 Oct 2023, 08:37wizechatmgr wrote: 27 Sep 2023, 17:33Coolant temp sensor determines fuel mixture at start - if it's hot, less is needed, if it's cold, the mixture is enriched.
