If your engine is knocking you have no oil pressure. make sure your oil level is where it should be.If so you may have a oil pump failure or you spun a bearing and are loosing you pressure there. if you are able, hook up an oil pressure test gauge to see if you have any pressure at all. If you have no pressure it is most likely your pump.

SOURCE: high oil pressure in my humer h2

First thing that i would reccomend is switching to 5w30 oil since this is what GM wants you to run in your hummer. Next i assume your gauge is pegged out and doesn't fluctuate. You are going to have to take your hummer down to the local dealer and have a computer hooked up to see if the gauge is bad or the oil pressure sender is bad, more than likely the sender. thanks for using fixya !! have a nice day

SOURCE: Hummer H2 engine won't turn over, key won't

Dead Battery? Bad starter motor?

Try pushing on the brake and making sure its all the way in park.

Turn the steering wheel back an forth a little to remove the key.

None of those work, Call triple A, find a shop.

Location of oil pressure sensor for 2005 H2 Hummer


The oil pressure sensor is behind the intake manifold. Remove the plastic cover on top of the engine. The intake manifold is the large black plastic piece under the cover. Reach in behind the intake manifold to access the oil pressure sensor. The pictures supplied show the view from the back of the engine, as if you are viewing from the firewall side of the engine

Why is my oil pressure gauge on my 2003 hummer h2 always read 80 when the vehicle is running, back to zero when shut off?


because when the engine is shut off, the oil pump is also shut off, therefore no oil pressure. no problem here!

Oil Sensor light keeps coming on 2003 H2 Hummer


There is a sensor located on the oil pan. If the plug-in to this sensor comes loose it or if the sensor fails, it will send the low oil signal. You are wise to check the oil to confirm it is not low.
