Have you checked alternator output on the van ?
Is the battery going dead overnight ?

djn, I believe you have some accessory that is on when the key is in the off position.
Check to make certain glove box light is not on when the glove box door is closed and the trunk light is not on.
If you have an aftermarket radio or any added accessories make sure they are not wired direct to battery voltage.
If all that checks out, disconnect the battery negative and connect a test light between the battery and battery cable. If the light is on you have a drain in the electrical system. Leave the light connected and begin removing 1 fuse at a time until the light goes out, that will tell you what component or circuit is draining the battery.
Last resort, you may have an alternator drawing the battery down.
Good luck and let me know.
Regards,

Can not start engine. There is no spark, changes distributor cap,rotor, coil. Still no spark to start
SOURCE: battery good alternator good starter good but
The proper way to troubleshoot a current drain is to disconnect one of your battery cables, and put an amp meter between the battery and the disconnected cable. Measure how much current is there, and then you can systematically pull fuses out of your fuse panel to see what circuit is drawing power. Some current is expected, such as the keep alive circuit for your radio, and a dome light if you have a door open.
You should be able to narrow down your search area, by your symptoms. If you have not had your alternator tested, do so, as sometimes they appear to be working, but have a current draw thru the voltage regulator.

You should check the electrical system at this point Get the rubber gloves out pull the wire off the distributor cap for the coil hold the wire close to the hole that it was pluged into have someone try to start the vehicle you should get a spark if you do then take out one of the spark plugs plug the wire back on the plug and touch it to the engine block and have to other person try to start the engine again you should see a spark again If you get no spark at the coil test it cuuld be a bad coil or the electronic ignition module witch is the most likly cause of your problem But if its sparks at the coil and not at the plug then eletronic ignition is likely good and the high votlage side of the coil is the problem hope this helps

there can be electrical issues like lose wiring..check all the wiring.. there are not many reasons because of which a battery drains out..
