mine fuel pump battered working.I"ve replaced it yet still won"t work. Looking through my publication a little closer I uncovered that if the oil pressure switch goes the end it will certainly shut off strength to the fuel pump. What I need to know is wherein the oil push switch is and also the an obstacle in changing it. Or can there be an additional problem? Fuses and also relay is good.
perform you listen the fuel pump come on for 2secs when key at operation position. If not check fuse and fuel pump relay.The fuel pump and also oil pressure sending unit is situated on ideal side the engine
Engine mechanically problem1997 Chevy S-10 4 cyl 2 Wheel Drive manual My fuel pump has shut down and also the truck no start. I"ll revolve the key but can"t hear any whirring native the fuel tank. I"m trying to check my bases before draining the tank and also pulling the fuel pump. Would the oil pressure switch completely shut down the fuel pump or reduced the press in some other way? ns was called to check the oil pressure switch, is over there a way to check it or do I simply replace it?
Oil push switch would not shut turn off fuel pump, but the fuel pump has actually a second route through the oil press switch. If the fuel pump relay goes the end the pump will certainly then run through the oil push switch ~ the engine gets oil pressure. This outcomes in extended engine cranking time prior to the engine will certainly start. Have you inspected all fuses, inertia move (if equipped), relays and wiring before going in because that a pump replacement? Repalce your oil press sending unit. Thanks for making use of ptcouncil.net. Com!
I have a 97 s-10 4.3 we adjusted fuel pump and relay now truck wont start cranks over hard starts sometimes wondering if oil push switch is problem
examine the fuel pump and oil press sending unit this is the one the powers the fuel pump once the engine fires up.
i am having a trouble w/ the oil pressure switch I have all ready put in a brand-new one and I still gain the exact same result. The oil push gauge is all the means to the right. I likewise replaced the fuel pump, ecm or computer, and also the fuel relays. I replaced the fuel relays in the glove box I believed there may be fuel relays in one more location however I could not uncover them, are there relays in an additional place as well as the glove box? ns drove the van to my house a month ago and acquired it to start about a week ago but now it transforms over however will no start. I know a good amount about cars yet this one is relay giving me difficulties I cant number out what i am missing. Execute you know what could be leading to the oil press gauge to simply stay grounding to the right prefer this?
hello there, girlfriend will have to an initial check that the oil pressure is through in specs with a mechanically gauge, if the is ok, the difficulty will be in the wiring, begin here.Mark (mhpautos)
whereby is the oil press sending unit on mine truck detailed above (2.2)? Also, if that is poor would this do it show no pressure on the gauge?
See listed below for location.Check the oil push with a mechanically gauge, if normal replace the oil pressure switch. If abnormal can mean oil pump and engine bearing.
The sending out unit is ~ above the best rear side of your engine. If the were bad then you would show low or no oil pressure. However to be sure put a mechanically gauge ~ above the engine to check out if the is correct or not.

I have a Fuel Problem, Started when the fuel pump died. Changed the pump, Cleaned up the ground. Pump does no come ~ above at rotate of key. Dad said can be oil pressure switch.

I have a 1993 chevy s10 with a 2.8L motor in it. The oil press sensor go out out the the side of the motor and also I changed it. Now my question is just how come when I replaced it and also plugged it increase up the fuel pump came on also when the ignition was off and also the key out that it and also didnt rotate off till I unplugged the oil push sensor. Can someone please assist me.
Sounds choose you have actually the wrong sending out unit, it had actually two terminals reversed as soon as it was made, or the plug is in backwards.GM had some systems that ran the fuel pump off a terminal top top the sending unit as a safety cutout. If the car was in a crash that ruptured a fuel line, there would be no fuel pressure so the engine would stall. When it stalled, there would certainly be no oil press so the move in the sending out unit would turn off and also turn off the fuel pump. That would stop it from pump raw fuel ~ above the ground.
so why is the fuel pump coming on and also staying ~ above as long as tht sensor is plugged up even when the ignition is off? additionally the truck wont even start because that oil push sensor go out and I changed it.
ns agree with doc ~ above the truth that girlfriend likely have either a bad or the dorn oil sender. That is offered as a redundant strength supply because that the fuel pump yet it IS not a low pressure cut off. The does not have the capability to interrupt the fuel pump, it deserve to only power it in the case of a relay failure.
