Engine light is on and the low oil pressure light is on. I try to start my 2005 Mountainer and it shuts right off. My oil was low so I added 2 quarts...still stauls and shuts off.

SOURCE: low oil pressure

usually that could mean a failing oil pump....or a clogged pickup in the oil pan, could also mean you have a leak somewhere. the car shutsoff because it protects itself from killn itself

SOURCE: low oil pressure at idle

how low does the oil pressure drop?? is it below 40?

Add the quart of oil. Oil also acts as a coolant.

Ok, lets take this from the top. I have a 97 f250 diesel. In mid may mine did the same thing. It's either one of two things. You have under valve cover harnesses (uvc). They slide in under your valve covers, you will see two wiring harnesses on the outside of the valve cover gaskets on either side of the block. Ok, it IS possible one of these slipped out of place and killed two of your injectors, causing the horrible running/ low idle/no power/ sounds like the truck is going to stall symptoms. The easiest way to check that is to unplug the wires while the truck is running and see if it kills the engine, if it doesen't unplug the other one on the same side of the valve cover. If both of these don't cause any change then you have a bigger problem, the IDM (Injector drive module).

FAIR WARNING: When you unplug the wires with the truck on it is extremely dangerous, it is 110 volt feed. It can kill you.

OK, the IDM is a silver box, 8"x10" approx dimensions, located on the driver side under the hood, over top the front tire. If you take the wires you unplugged and take a multi meter to them and they are dead, you have a bad IDM. This was the case with my truck. Ford designed the IDM to have a hole in the side to allow condensation to escape from it, unfortunately, this allows water inside and will short out resistors and practically kill half of your engine. Buy a new IDM on ebay for about $380. It takes 5 minuts to put it in.

I hope this helps you out man.

ur oil pump may be failin-there r sensors everywhere on new cars-keepin u from starting as safety measure-computer systems r complex n things dont always show on 1 scan-they kinda hav the mindset of a pc

Testimonial: "Thank you. I have spoken with 2 other mechanics who said the same thing regarding the oil pump. It's being looked at. So I'll post more once I know"
