Engine Performance problem
2003 GMC C2500 V8 Four Wheel Drive Automatic 50000 miles

My duramax diesel worked perfect exept for defective battery problems, replaced both 3 times. This problem is I drove it in my garage after a small trip ( under 50 miles ) now the batteries are fine but the motor won't start. The garage is heated. Seems to act like no fuel.

Start by checking the fuel filter for any water or dirt, a dirty fuel filter will give a no start or hard start. Plus check for fuel in the crankcase, if there is an excessive amout of fuel in the crankcase suspect leaking injectors, very common. Also ALOT of injector pump problems also very common.
