Chevy Silverado Sierra 1998 2006 Workshop Service repair manual

Top front of engine there inside a housing there is a heater tube going to them.

The Duramax fuel filter assembly is bad about sucking air. Replace the fuel filter assembly. It comes with a new fuel filter.
I need some good feedback.

clockwise

The air filter is located under the hood, passenger side, up by the windshield. it has a small retangular cover about 3 X 10 that pulls off

YOUR ELECTRIC FUEL PUMP IS THE DIESEL INJECTION PUMP.

In other words it won't start at all? The neutral safety switch may be faulty or a wire came off. It is located on the transmission.

mo me it sounds like low fuel volume i would check my lift pump

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.
