The truck runs and idles fine. It even revs up smoothly. Start driving it and it starts to spits and sputters.

Hello,

This will be one of two things, either the fuel pump is starting to go out or the ignition system is breaking down.

Here is a guide to help us see which on it is:

Key On Engine Off 35 - 45 psi.
Key On Engine Running 30 - 40 psi.

Also, if you can take a quick video of what the truck is doing it would help as well you can upload it here from your phone.

Please let us know what you find. We are interested to see what it is.

Cheers, Ken
