Van cranks, but doesn't start.
There are a number of reasons why your van will crank and not start. You can have anything from a faulty fuel pump, a bad crank sensor, an internal engine failure or too many other things to count. A mechanic would start by checking for fuel pressure and scanning the computer for any codes. If there is no fuel pressure then the voltage at the fuel pump would be tested to identify if it is a circuit problem or the pump. If it was a crank sensor then the computer scan tool would show a problem with the rpm signal. These can be complex tests so I would advise that you enlist the help of a certified mechanic, like one from YourMechanic.
