Duck,

Maybe you saw an image I posted showing the ignition computer getting drowned by a leaky wiper motor grommet. In any case, nothing in the passenger footwell would prevent your motor from cranking.

The problem in most cases is voltage drop on either the heavy cable between the battery terminal and the starter (caused by corrosion you might not see under the insulation) or voltage drop in the wire to the small terminal #50 at the starter, which would include any in the neutral safety switch.

Excessive voltage drop is caused by poor terminal connections or broken wire strands.

If you measure the voltage at the post where the large cable connects (not the cable terminal or nut) while a helper turns the key to the start position, you should see at least 11V if click-no-crank, or at least 9V if cranking is happening. Same at the rivet on the solenoid tab terminal #50 where the blue/yellow wire attaches.

Should you want to avoid bothering your helper, you can simulate the key in cranking position by using a jumper from the battery + terminal to the starter test terminal up by the oil dip stick.
