vehicle not starting

First you would need to check for spark, and if there is spark, then fuel pressure would need to be checked.

What about power to the solenoid or do you think the starter could be out?when I turn the key absolutely nothing happens, just pure silence,I need my van to start

Nothing was stated in your original question on what was going on. So, is the battery good? Have the battery checked, and clean up the battery connections. Any other clues?

Yes, the battery is brand new, lights come on, radio too, but when I turn the key, nothing, it's a electric starter with a comp.chip, I had the barrel refurbished, new starter switch put in, it's mind boggling, and I'm using my spare key witch is new so I know the chip in the key is good,I appreciate your help and advice on the matter so if there's anything you can think of ,I'd love to know,thanks

The key...do you have the original key? It may be in that key if it was not programmed for the ignition switch.

To be honest with you I'm gonna have to say that it is the new key you got I think it might not be programmend yet take your vehicle to the dealer that's your best bet
