01-04.5 LB7 Duramax Powertrain
2004 duramax Deisel will not start.
It has been hard starting for about 2 weeks and usually starts after about 15 seconds of turning over.
Today it won't fire up.
It is about -20 C or 4 F.
I checked the prime and it was pouring fuel as soon as I opened the bleeder screw so prime is good.
Battery...
