Question about Cars & Trucks
And it keeps losing its prime has new fuel lines from the pump and has new fuel filter housing.
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

duramax diesel trucks do not have a lift pump. start with the simple things make sure your fuel filter is tight and check the shreader vlave on the fuel rail if that don't help check the filter housing for a leaks arround the heater element or a crack in the housing itself

Most likly the filter housing needs to be replaced and or the fule lines to and rom the housing. the housing has the plunger on top and the filter screwed under. The plunger goes bad on these and causes air to enter and then become air locked. this is also very comon on the IPR with the fuel filter housing mounted behind cab on frame rail driver side. road sault gets to these and degrades the unit untill it sucks air. On the c 4500 you need to get the oem fuel lines because of the tight space restrictions to route the lines. the OEM lines are molded to make the tight bends required.
Hope this helps... Good luck
