wont start

[Duce Stroker]

Its a 97 F350 7.3 it ran just fine. i put a new down pipe on it, drove it around and maybe a couple weeks later it wouldnt start. I was trying to start it and could hear one of the relays clicking, so i replaced 2 of them, but now its doing the same deal and now no gauges on the dash turn on. Any ideas?
