why dose my van shakes when i turn it on
Sounds like you need a tune up and possibly spark plug wires. Also do you mean vehicle shakes only when starting or also at idle.
If it only shakes for a little bit then smooths out, look for steam out of the exhaust on start up, if you get some that is a sure sign of a blown head gasket.
