When my wife defined the minivan would not start, first assumption is battery. i connected cables, and everything had power; but when attempting to turn over ther is nothing. disconnected cables verified that everything still had power, could not turn over.Is this potentially an ignition issue?
Disconnect the ground cable from the battery and check the cable going to the starter. (located on the starter) Make sure it is tight. Re-connect the cable to the battery ground.

could very well be the relay for the power door and possibly the interior light relay... they are located in the fuse panel under the dash.

Unfortunately, no.
Toyota began installing the cabin air filters in the Sienna product starting in 2003.

I would guess that you have a stretched or loose serpentine belt. Common problem.

Yes it is all related. It sound's like your speed sensor (VVS) has gone bad. There are two of them, one is an in put Velocity sensor and the out is the out put Velocity sensor.
Your going to have to get the Van scanned to find out which on has gone bad. Most of the time it's going to be the out put sensor and it not that hard to replace.
You can do it your self or a transmission shop, as for getting your Van scanned for the codes to let you know which sensor when bad. Auto Zone or Parts source will scan for free and can give you instructions on how to locate and replace the sensor.
Good luck and hope this helps.

The drain plug is on the bottom of the transmission. Its torqued to 49 nM.
1. Remove tranny oil pan drain plug
2. Drain old fluid (roughly 2-4 quarts)
3. Reinstall drain plug.
4. Measure amount drained in a 99 cent orange juice pitcher from Walmart
5. Pour back the same amount drained using Toyota Type T-IV fluid (available in 1 quart bottles from a Toyota dealer.
6. Start engine and shift slowly through all the gears ending in Park.
7. Check fluid level on the dipstick. Add fluid, if necessary, to bring the level to a point inbetween the COLD and HOT marks on the dipstick.
8. Go for a 20 minute drive and recheck fluid level. Add fluid, if necessary, to bring the level up to,
but not beyond, the upper half of the HOT range on the dipstick.
As in 1973, NO FLUSHING is needed and NO FILTER REPLACEMENT is needed, NO PAN REMOVAL is needed. As, as in 1973 todays Toyotas have a metal mesh filter screen that doesn't ever get clogged except in rare cases of transmission operational abuse, including failure to ever change the fluid for 150,000 miles or more.
