Van will not start

Hello,

You need to check for spark and fuel. When you turn the key in the on position you should be able to hear the fuel pump turn on for a few seconds. You will need to verify that and for the spark if you pull a plug wire and stick a screwdriver into it and hold the shaft of the screwdriver next to ground a spark should jump to ground if you have spark.
