I had that problem, not with the oil pressure but with power in general... check it with a computer if you check engine light is on.... maybe its the o2 sensors.

Have oil pressure but gauge goes 80 to 40 to 0 doesnt tick at 0 turn off turn on gauge goes to 40 than to 0 no tickin


Possibly the gauge is off or bad. The only way to know your true oil pressure is to hook up a mechanical oil gauge to the fitting where your gauge sender is. Any mechanic's shop would have an oil gauge.

96 Chevy blazer how do I get out of safe mode ran low on oil now runs an drives but won't let car go fast past 2000rpms


The computing system on your vehicle has no safe mode for running low on oil . The only thing that will happen is the check gauges light will come on.
The oil pressure gauge is an analog device that is located in the IPC. The oil pressure gauge is operated directly by the oil pressure sensor circuit. As the engine oil pressure changes, the resistance of the sensor and the current flow in the oil pressure gauge changes. The current flow in the oil pressure gauge causes the needle to move in order to appropriately display the engine oil pressure. A sensor resistance of 1ohms will display as 0 kPa (0 PSI) and a resistance of 88 ohms will display as 80 kPa (80 PSI ). The IPC also monitors the oil pressure sensor circuit and interprets the current flow in this circuit in order to determine when the engine oil pressure is too low. If the oil pressure is too low, the check gauges tell tale will turn on. The oil pressure sender is located on the left side of the 2.2L. The 4.3L engine, oil pressure sender is located at the top left side, near the distributor/high voltage switch.
Try disconnecting the battery cables an hold them together for ten minutes , reset ECM !

I have a 1994 GMC SUV, early in the morning when i start the engine the oil pressure is normal. but whe it warms up the oil pressure goes to 0, when I hit the gas petal the oil presssure goes a little...


You need to have the oil pressure checked with a manual oil pressure gauge you may have a bad sending unit. If the you oil pressure is the same with the manual gauge then you have a oil pressure problem.

Oil pressure gauge goes to 0 when idled, but goes


You could try thicker oil or stop using synthetic or add some lucas oil treatment or change the oil. The sender could be bad too. A diag is in order because if there is no presure the engine will soon die.
