Hope helps (remember to rate this).

Sounds like it is either a bad coil pack, cam position sensor or crank position sensor. The coil pack delivers the spark to the plugs and the 2 sensors tell the computer when to tell the coil pack to spark.

DO'ES THE VAN TURN OVER ? DO'ES THE VAN HAVE THE FUEL PUMP RUN LONG ENOUGH TO BUILD FUEL PRESSURE?IF YOUR FUEL PUMP AND STARTER ARE WORKING THEN CHECK FOR FIRE TO THE PLUGS. YOU MAY NEED TO GET THE CODES READ TO FIND THE PROBLEM IF YOU HAVE FUEL AND FIRE.ONCE YOU GET THE STORED CODES,REPLACE THE SENDER THAT CAUSED THE CODE OR REPAIR THE WIREING TO IT.

here is the diagram for your engine...
