Jeep no start, crank, sudden...

5 weeks ago ran fine, pulled battery while I was gone. Got back and put a new batt in, strange things:
-cranks but doesn't fire.. at all
-no whine from fuel pump at all
-swapped fuel pump relay with horn relay, same thing
-have 12V at fuel pump relay
-instrument cluster acting weird: fuel gauge doesnt' move, battery voltage doesn't move, but idiot lights come on
-think the no start is the fuel, I'm going to hot wire pump and see if I get it to run.... but I think it's not commanding the fuel pump relay to shut... loss of voltage somewhere. Also, every time I wiggle the key or try to start it the radio goes on/off/on/off.

Recommendations would be appreciated. It is REALLY dirty, so I plan on checking all the grounds. Just strange that it would run fine and then not.

wiggling the key causes loss of power....I'd check ignition switch/lock cylinder as well...that's what sends power everywhere.
