2003 Duramax Starting Problem
 

My 03 Duramax cranks 7 to 8 seconds (longer when cold) before firing, then runs good. I thought maybe crank pos. sensor. Is there an easyway to check and replace this? Any help on this would be great.

Thanks

Check for a leak in fuel pressure somewhere first. Have you tried pumping up at the fuel filter before cranking? Try that and see if it improves cranking time.
And welcome to the site dude. :c:

does it feel like its got power after its running? it might need a fuel filter, when was it changed last?
