SOURCE: 2003 Mitzubishi Lancer oil pressure light only when braking

It might be oil pressure sensor or oil pump is faulty. Also might be problem with winter conditions driving oil gets more viscous. If you recently did oil change might be the reason for that too. Change the oil for 5W-30 (for winter only), instead of 10W-30. If problem persists check/replace oil sensor if wont help loook for oil pump.
Please kindly let me know if the information was usefull for you or you need more info
Good Luck

Try replacing the Oil Pressure Switch/Sending Unit. It should only be a couple bucks at your local auto parts store.

How to replace 2003 mitsubishi lancer fuel level sensor. My fuel gague is going half to zero when the tank is having fuel. It's not showing exact fuel left


Hi.

You need to release pressure from fuel lines cutting power to fuel pump.Turn on engine and remove fuel pump fuse. See:How To Release Pressure
Then disconnect battery.
Take down the fuel tank working from under backseat and underneath the car.
The fuel sender is located inside protective Housing. Remove housing held by 4 screws.
Disconnect electrical connector.
Disconnect the two hoses connected to sensor. Be careful with fuel that may still spray at pressure.
Perform operations in reverse order to reinstall.

Car acts like its not getting fuel car cranks but


Sounds like the fuel pump may be intermittant...which unfortunately is located inside the fuel tank...there is a service port on the engine that allows you to test the pressure of the pump...it is located on the fuel rail that feeds the fuel injectors...this would be a good place to start....other possible problems with the fuel system are the fuel pressure regulator, fuel injectors, tps sensor, and possible but unlikely the PCM(computer)...A way to test the pump without tools would be to bang on the fuel tank and see if the problem ceases..if the pump starts working, then it is intermittant and I would suggest replacing as it may fail again...and quite possibly, when youre in a bad place or area

Poor performance on up hill drive


This could be caused by a low fuel pressure or poor plugs/wires. Do a fuel pressure test, if low replace filter, if still low replace pump. Also replace spark plugs and wires if you have not done so. If check engine light is on you can bring vehicle to local parts store to have them retrive trouble code. Thanks
