03 chevy 3500 duramax low oil pressure light - Silverado 3500 Chevrolet Cars & Trucks

Either the oil pressure sensor is faulty or it is loose. Have a shop check that out for you.

take it back to the dealer and have them reset the oil change data on the computer.. thats the issue with this jeep we have here .. they did not reset the oil change interval in the computer..simple fix.. sorry they overlooked it or the tech got lazy..

why?

These will help.Thanks.

Check spark plugs, leads, distributor cap & rotor arm, fuel pump, fuel filter, coil pack(s), relays, replace any items that are suspect IE Fuel filter which has probably not been changed since new even though they should be changed on all vehicles every 18 months, all of this can be done at home & will save you a lot of bucks in mechanic/garage fees,

This will help.

Thanks.

could be some bad injectors...does it smoke real bad?

who did a conversion on this truck???? the duramax is a common rail engine and can not handle wvo or sve. it will destroy your entire fuel system in no time on this truck. if you want to do a vo conversion you need to get a diesel with an inline injection pump or one of the older powerstrokes. i would suggest you quit trying to run wvo through this truck if you do not want to do a lot of very expensive damage

Check your " FUEL FILTER " for clogging. Work backwards toward the fuel supply tank, Hope this helps.

I had the same problem it turned out to be the injector pump witch gm covered it.
