    daily-driving the truck for 2-weeks now, no issues as of yet. Drove it Saturday morning, parked it at home and attempted to leave for work this morning and it cranked with plenty of power but wouldn't fire up. I replaced the fuel filter 1-week ago as part of complete maintenance update and read somewhere after the fact the fuel pump will sometimes go out if the truck has a lot of miles on it (I'm at 130K but it is what, 14 years old?) so I guess the 1st thing to do is check the fuel pressure on the rail or see if I'm getting anything? What else should I be looking at besides the obvious fuses/relays? is there another relay in the fuse panel that I can swap with the 1 on fuel pump?

    fuel psi at the rail....any relay in the fuse box will work. Was the security light flashing? Could be the passlock acting up
