2008 van no crank help!

2008 express van. gauges went crazy and now it wont spin over to fire up. I have no siginal at starter. no fuel pump when key turns on. checked all grounds everywhere. good battery and connections. and my scanner will not comunicate with the vehicle. could this be a bad computer ?

I give up . had it towed to dealer. will post back what the fix was. it may help someone else in the future.

took it to the dealer it was a bad ECM it cost $725.00 out the door. I give up . had it towed to dealer. will post back what the fix was. it may help someone else in the future.
