Check to see if the fuel pump is kicking in,
when you turn the key on without starting the van you should hear it kick on for about 2 seconds,
It could be...
A clogged fuel filter...
Blown fuse for the pump..or bad pump relay..
Bad fuel pump

The distributor in that engine can only be installed in one position. The hold down is built onto the distributor meaning when it is installed and the engine runs the computer is responsible for the timing. The distributor will move a little but won't correct major timing errors.

Paul is right you can go to radio shack or autozone schucks or any parts store and ask for the removal tool it cost $20.00 tops. Trust me you don't want to undo the dash as the air bag could detonate if you shorted the two wires that can control it and it could kill you.
