SOURCE: no oil pressure and i just changed the oil

You need to put a mechanical gauge on there and check actual oil pressure...problem may not be the switch but in fact there may be no pressure. Does the engine make noise when running? Do you have the correct switch? What was the problem that caused you to replace the switch?

SOURCE: i have replaced the fuel pump on my 1994 pontiac

Are you sure that the fuel pump is properly installed? Have you tested the fuel pump circuits to see if they are working properly? Did you also replace your fuel filter? (It could be totally clogged up) Have you checked to see if there is any fuel pressure at the fuel rail or are you just assuming that the pump is not delivering fuel to the injectors? Have you checked your fuel injector circuits for power and for injector pulse from the EngineControl Module? Have you scanned your Engine Control module to see if you possibly have a Crank Sensor or Cam Sensor problem?

The oil pressure switch only keeps the fuel pump running once the engine starts. The fuel pump should run for 2-3 seconds when you turn the ignition switch to the "Run" position to prime the injectors. The oil pressure switch is the problem only if the engine will not continue to run on its own after it starts up.

2002 jeep grand cherokee, oil pressure guage to the maximum high limit. Oil level okay, Oil change mechanic says common among these cars. I'm still curious what to do. thank you. 6 cyl.


It may be that the oil pressure switch is faulty. Find the oil pressure switch and unplug it and see it it goes to the min. If it does I would suggest getting a new switch. Also, the oil pressure switch wire might be grounded out against the body or the motor somewhere.

My grand am gt 2003 has the "oli pressure light", light on. what should i do. what part do i need? i do not want to blow my engine up


OK, first I would check the level. Then, I might check the pressure at the oil switch using a gauge. If it has pressure there, the oil sending switch may be bad.

Or, the viscosity of the oil may be too thin, or the oil filter may be clogged which would mean that changing the oil and filter may solve the problem.

How does the engine run? If it runs without making any knocking or abnormal sounds, then it may be a false low oil pressure reading.

I would try to get this issue fixed as soon as possible, though, as these things won't get better by themselves.

I need to change the oil pressure sensor, where is it found


The oil pressure sending unit is located to the right of the oil filter and just above the starter motor. This is on the 3.4 liter V6.
On the 2.4 liter 4 cylinder the switch is on the left (drivers) side of the cylinder head.

Oil light came on when idling; oil changed; still happening occasionally. If I put it in park or neutral and rev it - the oil light goes out. Could it be the oil sending/pressure unit? Is there an easy way...


make sure are using a genuine dodge oil filter and correct grade of oil to check further you need to have the oil pressure checked using a master gauge a garage would do this for you if ok replace pressure switch if very low could be pump and bearing wear is the idle speed set too low i would check this
