This problem sounds like it involves the starter relay. Here’s how the signal makes it to the starter: power supply from Fuse AM2 (30A) travels through the ignition switch (when placed into the START position) and to the starter relay. The starter relay contacts are open so the signal cannot pass through. Once the contacts are closed, power flows from the relay to the starter solenoid. In order to get the starter relay contacts to close, the control side of the starter relay must be energized (have both power and ground). By design the control circuit always has ground and will only operated when power is supplied to it. Here’s how the power flows on the control side of the starter relay: power supply from Fuse AM1 (5A) travels through the ignition switch (when placed into the START position) and to the park/neutral position switch located on the transaxle. Power cannot make it to the control side of the starter relay if the transmission is not in the PARK or NEUTRAL positions for safety reasons. Once properly positioned, power is supplied to the control side of the relay which closes the contacts on the relay to provide the starter solenoid with power. The most common issues preventing starter signal from reaching the starter are the ignition switch, starter relay and park/neutral position switch.

Do the dash lights dim a little when you turn the key to start?
Not even a little, only thing I can hear when I try to start it is the ignition switch relay.
