If the solenoid is clicking when you turn the key its very unlikely to be a relay fault, the relay controls the feed to the exciter wire which must be working for the solenoid to be clicking. If you haven't ruled out the battery completely do so by attaching jump leads, if that makes no difference you ideally need to check for a volt drop between engine and battery earth terminal and also main starter feed to battery positive, (the latter can be a problem with difficult to access starter motors tho.) if all wiring is ok its most likely the motor itself, if you can get to it give it a tap with something and see if it makes any difference. If it starts after a tap then its most likely the starter motor.

start all over! git rid of fuilter,ole fluid, and flush again. NEW FILTER,GASKET,FLUID, and see tuat will happen. oh! and reprogram the key/fob.lol!
