i have recently replaced the injectors on this truck 4.3 vortec with w in the vin back in june of 07, again in april of 08 and fuel filter and aug of 08. the truck is doing the same exact thing stalling, back firing, hard start, and dying, smells as if flooding out. I have replaced the fuel pump, fuel pressure is ar 60lbs, just did a complete tune up replaced map, egr, o2 etc. i have used aftermarket injectors and want to know is this the problem or could it be something else causing my injectors to keep going bad? I am frustrated and at the end of my rope with my truck.
