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 !

1988 Honda accord oil warning light on, does not turn off. Oil level is fine. what causes the light to come on?


The oil pressure switch causes it to turn on when there is no oil pressure. There is oil you say, so you need to check if there is oil pressure when you start the engine. Simplest test even without gauges is to remove pressure switch and start engine briefly and turn it off. If you have oil pressure you will have oil shooting out of the switch hole. Replace switch. If you dont have check iol pump.

I have a 1989 chevy s-10 blazer. i have replaced the fuel pump, the fuel pump relays and i hooked up the pump for a dry run before putting it back into the tank, the float neddle works but the pump is not...


If you didn't damage the fuel pump with the dry run, and the relays are new, and the wiring is connected properly, it should work. If you have checked all the fuses in the fuse panel and none are blown, I don't think the fuse would be anywhere else. I've got one idea you can try. It's a long shot, but I've seen it happen several times. The oil pressure sending unit or switch, is tied into the fuel pump wiring. If the oil pressure switch is bad, or the oil pressure is low, the fuel pump will be shut down. Disconnect the oil pressure switch and use a piece of wire or a sturdy paper clip and make a jumper wire. Plug the jumper into the end of the oil pressure switch wiring connector and try the ignition to see if the fuel pump works. If that doesn't work, I'll do some research on the fuse location. Good luck.

Hi, i have a 1988 toyota conquest. the oil light continously stays on. But when i rerve it up the light goes on. Oil is full. Im thinking its the oil pump? i dont think its the oil light sensor but im not...


If oil level is OK, then it is possible that the warning light pressure switch which is screwed into the engine oil pressure system is faulty and setting off light and needs replacing. There could even be oil leaking out of the switch. The switch is usually located near the oil filter and will have a wire connected to it.
If after replacing switch and light still comes on, check to make sure wire is not making contact with the engine because of cracked insulation or it could also mean badly worn engine bearings. It is unlikely to be the oil pump as these hardly ever fail.

Car will not run


The fuel pump is inside the gas tank.There is no fuel shut off switch unless it runs through the oil pressure switch circut,meaning if the oil pressure gets low enough,it shuts off the fuel pump to keep from damaging the engine.Good luck,

Where is fuel relay


The fuel pump relay is only for the fuel pump priming when you turn on the key. After the vehicle starts the oil pressure switch takes over and runs the pump. If the pump is shutting off after the motor is running the oil pressure swith is probably bad. Let me know if i can help you further.

Help have no spark


I had the same problem with 1991 s10 blazer.
check the oil pump pressure switch and current to the switch.
The computer will not allow the spark plugs to fire if the oil pressure switch is not sending a signal to the computer that the oil is flowing.
My problem was a short in the wiring that was not sending enough current to the oil pressure switch.
I had to crank the starter three or four times at 5 second intervals until the current was suffient to operate the oil pressure switch.
The switch is a round cylinder device located on th drives side of the engine near the oil filter.
Good luck!!
