Replace the oil sender switch, its behind the right side cylinder head. Its alittle hard to reach, suggest buying a new one and matching a socket size to it.A socket and ratchet with exstention should get you to it.
-faulty oil pres. sending unit -faulty oil pump
The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.The truck doesn't have a freon pressure gauge. That is a tool that the repairman/mechanic has.
It's most probably low on oil. The shifting oil confuses the guage. Add oil.
Bad Sender. Bad guage.
Need to check fuel pressure with a gauge first. Then check fuel pressure regulator. Need to check fuel pressure with a gauge first. Then check fuel pressure regulator.

Start with checking the fuses.
low coolant
It is inside of the fuel tank. You must remove the fuel tank to service it. You need to check the fuel pressure with a gauge FIRST. I would give you fuel pressure SPECS. But you did not say what year it was.
No, it will not cause that.
Low oil level, low engine rpm, low oil pressure, failed oil pressure sensor.
1500
Hopefully (for you) just a bad oil pressure sending unit Install a manual gauge to actually check the vehicle's oil pressure
