So, I've been reading all these other posts with the same problem and I just can't find an answer that makes sense - neither have I paid anyone to come try their magic at it.
This is what I HAVE tried -
Replaced starter
Replaced alternator
Replaced battery
Swapped out Starter Relay
Tried starting in neutral
Tried resetting security by hooking up battery while key is on, locking and unlocking both doors and trunk with key.
Now, I don't believe its a starter or starter cable problem because.... the ECT box is what clicks, not the solenoid. I pulled the cover off of the ECT today and just found a pcb with plenty of resistors/transistors but no relays or anything that looked like it could be clicking... Does anyone know if there may be another relay or fuse Behind the ECT in that passenger kick panel? Anyway, before I keep going on for days i'm going to stop and ask for ANY SUGGESTIONS, THANKS!

Hi!
clicking? - simple continuity check: remove the wire that goes to the starter soleniod and connect it to a 12 volt bulb and connect this bulb to earth , then try and " start " car by turning the key , this bulb should light-up, if it does , then the power is there to try the next step .
With everything switched off --fit a long heavy duty wire to the starter where the old wire was removed from ,-bit of a sod! and with the car in neutral (especially important for a manual drive ) , flick the other end over the live ( plus) battery post -the starter solenoid should activate and turn the starter , this will prove the starter is working ( no-need to remove for further checks -it's ok!) , now : using the original wire , and using the relay diagram ( the switch is the relay !!!!! )-fit a 40 amp relay between the starter and the battery using the heavy duty wire - this original wire will now only be required to activate the relay internal bridge to supply a higher amperage directly from the battery straight to the starter - I found this trick earlier in this forum somewhere --BRILLIANT CURE - Many Thanks !!!
If the starter does not work then you may need to replace the brushes, especially if the starter is very old .but do the relay mod anyway!
