2001 GMC Sierra cranks, but won't start. In the past the security light would come on while driving, and it would start some times and other times crank and not start. Let it sit with the doors locked, 5 10 minutes, it would start. This was happening off and on. Now, it will only crank. Pulled code P0404. EGR valve stuck open.
have the same problem?
