Well, I went and got a fuel filter, just in case, changed it, the relay switch, the fuel fuse, and same thing happened. Okay?? Then BAM, after a few curse words, I lightly tapped the metal covering to the inertia switch, and boom stuttering, choking, rough running, shut the truck off, and pressed down on the inertia switch, for once it clicked! the button is under a rubber cover, i was mistaken it all as the button... after that it ran well... oh and I am cursing purolator btw... Made in china fuel filters? thanks.
