The pressure gauge in those trucks operates off a 5 volt and low reference signal from and to the ecm. I know, not what you wanted to hear. Been there.
Try giving slight taps to the cluster and see if it's a loose pin or connection.
You may need to get access to live data scan tool to diagnose it. Other then that , check wires from sender to ecm pins. And cluster pins. Could be a faulty cluster.

What would be causing a 1993 Audi 90s to have no oil pressure I took a pressure check on the oil sending unit and had no pressure But the pump is working and there are no clogged tubes?
If you checked the pressure with the sending unit in the car, it is possible the sending unit itself may be bad!
How do you check the oil pressure?
You need to remove the oil sending unit and install a oil pressure gage in it's place then start engine and read gage. Iwould tell you were the sending unit is but you did not say what you are working on.

Oil light is on but there is oil in the car?
Oil pressure could be the problem - OR - Oil sending unit if the oil light is on it means the oil pump is not working or faulty.it doesn't mean there is no oil.
You have just had your oil pump changed but oil light keeps coming on any ideas?
First, hook up an oil pressure gauge to check if the sender for the light is working properly. The light should come on when the pressure drops below 5PSI. If the light is on but the pressure is above 5PSI, replace the sending unit for the light. If the pressure is below 5PSI and you just replaced the oil pump your bearings are probably worn beyond limits and need to be replaced. This is a major project and you might consider just buying a remanufactured engine at this point.
