Did they do a fuel pressure pressure test to determine that its fuel pump? And if so what was the p.s.i.?It should be around 55 to 60 p.s.i. a few pounds under 55 p.s.i. Pump needs replaced, Your shop should have chk. this when it was there the first time. Did they by chance chg. the fuel filter, that can hinder it from starting too.

Testimonial: "it was the fuel pump thank you"
I experienced this problem, intermittant failure to start. This procedure must be done with the truck RUNNING.
Remove the cover off of your ignition switch. On the top there is a small wire connector that, once the truck is running, should be disconnected. This will turn on the 'SECURITY' light. All will be better, except the security light will be on at all times, much cheaper than replacing the ignition switch, however.

i think if you checked the sparking plugs and map sensors then check your distributer its maybe not delivering the current nedded to perform the spark to some of the cylinders
