2003 6.0 problem.....

I've run in to something unexpected today, blew some fuses while screwing with third brake light wiring, replaced them, now when I turn the engine over it fires and immediately shuts off? Any ideas on where to start with this one?

nobody? Is it completely unrelated? I've rechecked all the fuses...no change. Is there a fuel pump relay or fuse somewhere other than the panel? I pulled the wiring harness plugs apart that are just in front of the fuel tank on the drivers side frame rail....but they are back together and tight. Still the same thing, cranks, fires and shuts off..... help?

Get to the tech folder, pull your workshop manual - I'm sure you'll find wiring related troubleshoot information.....
