Start at the back of your van:
Alternator belt ..... tight?
Not burnt on the edges?
Blue wire with the square connector plugged in?
The two wires to your starter on nice and tight?
With the ignition off, remove the negative cable from the battery.
Tap it a few times to the terminal, there should be very little arcing.
You can put an amps gauge between to negative battery terminal and the
negative cable and read the amps, you shouldn't get hardly reading of
draw.
With the battery reconnected check any accessory electrical lug on your
fuse panel with the ignition switch off, you can just do this with a neon
test light ....... you shouldn't get any light.
If you do it'll be your ignition switch that is bad.
Also if accessories have been added like driving lights, additional horns
the relay sometimes stays closed and draws current, even if the accessory
doesn't operate unless the ignition is on or the accessory position is
actuated.
Your AFM has a switch (tiny points) that run your fuel pump, they should
be open when the actuator rod is in neutral location.
If you have a battery cutout devise, be sure its wired to be active only
with the ignition switch in the run position.
(I'm dead set against additional solenoids at the starter and additioinal
batteries but I hope this has been of some use to you.)
