I've had to prime 3 times in the past 3 mos.
 

I drive a 2007 Chevy Silverado with a Duramax diesel. On three seperate occasions since April, 2013 I have cranked the truck, it ran for 15 seconds and died. On each occasion priming the engine got it started again. Each of these incidents happened about 1 month apart. The second time this happened the engine light came on and I got a code of PO 102 Mass Air Flow (MAF) Circuit Low Input. That's the only time that light has come on. I had the fuel filter replaced after the first time so that didn't fix it. Is this warning code just a coincidence and unrelated to the engine losing prime or do any of you guys know what this diagnostic code would have to do with this problem. Thanks for your imput.

it could be a couple things. duramaxs have a bad problem with the bleed screw leaking on the top of the filter housing over night. wont show any fuel around it but allows the fuel to drain out of the filter. they make replacement bleed screw that are metal that seem to fix this problem. it could also be the filter housing is cracked. or bad injectors.
