Truck died now won't start

[509country]

So I'm a mechanic but this one stumps me. I was driving home tonight and suddenly my battery light flashes in the message display then all the guages stopped and it shut down and won't start. I have fuel pressure and it's a new battery and the alternator is good. I checked my fuses and they are all good. I had a tuner on it and I thought that may be it so I took it off and it still won't start. Any ideas? I see stuff about the cruise control fuse but I don't know.

what type of tuner?, anyways, you should reboot the ECM, Unplug it completely, and let it on seat for 30 minutes to discharge, and static can take more than 2 seconds.. Try to reinstall, and see.

If not, you may have one of the bigger 'box" fuses under hood blown. Good luck !

It's a hypertech tuner and I will try that. It's at work and I left town for the weekend but I'll have a coworker run out there and try it tomorrow

A coworker of mine had this issue. Turned out to be a bad computer.
