I just purchased a 1995 Wrangler Rio Grande edition 2.5 L
All the gauges work EXCEPT the oil pressure gauge. It peggs out when you start the engine and stays that way all the time you are driving. When you shut off the engine it drops back down to zero.
How can the problem be diagnosed? Sender bad, gauge, or wire off or something.
Any ideas out there with you experienced guys? ? ?
