The prob seems like you have connected the power to your stero from the wrong place. You cut into live a wire for the power, this should be connected at the ACC on your fuse panel. Also make sure you stero has a good ground! Frankster016

Is there a oil safety switch on 2002 Chevy s10 zr2


You have a oil pressure switch which is located by the oil filter,it is screwed into block,just removed electrical connector,get wrench and remove.
  • When the oil pressure is either high or low it will either turn the oil light "on" in the dash or move the gauge to the extremes
  • Undetected high or low oil pressure can result in internal engine damage and/or gasket leakage. Here's a picture of what it look's like.

Oil pressure gage stays at 80 only goes to 0 when not running


Replace the oil pressure sending unit, they are notorious for this problem.

Truck run fine / started it in the am it had top end noise// oil is ok / i took oil filter of and cut it open // filter looks clogged i put a new filer and oil in and it still has top end noise when warm...


Sounds to me like the cam bearings are gone as that is where you get your oil pressure . most of those have to be pressed in after the motor is pulled out and tore down and going that deep i would go ahead and rebuild the whole motor while you have it out.

I have a 2000 Jeep Grand Cherokee and the oil gauge is going from 0-50 psi. There is oil in the engine. Should I be looking at the gauge or the pump for the problem.


the 1st thing to do is hook up a mechanical test gage and see what the pressure really is, the one used in the truck is electronic and u could have a sending unit problem, if the mechanical test gage show the same readings u will need a new oil pump, this assumes the engine doesn't have any bearing knock type noises

Oil gage buries all the way past high. After driving with it like that for a while, the truck engine konks out and will not start. Last time we waited on the side of road for 40 minutes and then it started...


Do you believe oil gage? Oil psi sensor can go bad. If PSI correct then is PCV valve clear?
I'm more inclined to think you have some kind of electrical problem, false gauge, ignition quits or fuel delivery problem. Extreme high oil PSI would blow out your engine seals, leaking oil everywhere. When you get high oil psi, does removing oil cap make it drop? Do you have good clean oil and filter?
When it quits do you have spark, fuel to delivery system? (throttle body or fuel inj) High oil psi shouldn't make truck hard to start. Baffling.

Oil gage drops to 0


You may have a bad oil pressure sending unit. The kit they are talking about, I believe is a rebuild kit, not the entire pump. Usally the kit consists of a couple rotors and seals. You would take the old parts out the oil pump housing, and install the new ones. But you want to make sure that all the clearances are within specs. I'd try the sending unit first.

Check gages light turns on and doesn't go off. Already had the oil changed, the oil pressure needle keeps marking 0. It had the same problem once but I changed the oil and kept working fine; then about 2...


At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana

High oil pressure


You can't go by the gage on the dash, you need to hook up a manifold gage to get an accurate reading. Did you check the oil filter bypass valve AKA oil relief valve?

2004 GMC Sierra High Oil Pressure


if it is electrical oil pressure sensor I would start there. The best way to see if you have a major problem is to use a mechanical oil pressure tester. Take off the oil pressure sensor and put the mechanical tester on. The tester should come with a Gage. If it comes within your trucks oil pressure range than all is fine and replace the sending unit and see if that don't help your problem.If the tester runs high then the oil pump is bad or your cam-bearings could be the problem. But with cam-bearings you would usually get a low reading.
