Now it's from bad to worse. I bought a used LX cluster from Facebook marketplace to test with. I can't remember the year. I know some models are different, but I'm just trying to test the oil pressure, so I plugged it in. Good news - the oil pressure was correct, so I have a bad stepper...
I have had the truck for a year, and have learned a lot from this forum. I am stumped on my current issue.

Starting a few days ago, when starting the truck, the oil pressure gauge goes straight to mid-range, then steadily climbs until it is pegged on high.
I changed the sending...
