I need all you nitrous guys...

Its gotta be something else. It was working perfect, it got hot, it doesnt anymore. Replaced the solenoid, it still doesnt work, took it out, checked jets, reassembled, still not working. Dad sais he checked plate and jets for clogs, nothing he can see. Sorry, for the record Im not a nitrous guy, so yeah, me and him are ending up arguing more than solving problems. I should look at it myself, he keeps saying, "I already tried that"... thanks for the help guys, and any other ideas are appreciated.
