No start as in no starter action, no clicks has a fully charged battery with a battery tender on at all times. Cables have all been cleaned and still nothing. Is there a way to jump it to see if the starter motor is working?

If everything battery and cable wise is in order, insure "S" terminal's wire is still connected on the starter solenoid, if it got knocked loose, this is probably your problem.

Let's say it is still on there, still no crank.

Insure you are in "Park" take "S" wire off of the solenoid touch a jumper from the battery to "S" terminal-only tough it, if you leave it on there and it cranks, it will not stop until you get it loose.

Touching, would be like turning your key to "start", it is only for a few seconds.

Key off-it will only crank or bump the starter.

Key on- if it cranks, it may start up.

If this cranks it, you know the starter/battery cables/solenoid/and battery are good.
If you have a security system could be preventing it to crank.

Picture below.

No clicks at all, there are a couple of fuses to check first, the fuses #31 and #103, both in the central junction box which is located behind lower left side of dash.
