pulled the starter from a 2ltr camry, cause it looked identical. Tried to install it and it hits one of the coolant lines and is like 1mm away from the bolt holes to line up. LOL. So then i decided to pull the motor from the housing and see if i can swap them over, but no, the they have different sized drive gears.....................FFS why so stupid?
 
Time for some angle grinder action

im seriously stuck now, i have no idea what the problem could be except possibly the starter relay. 
 
Put on the newer starter motor (possibly fuked as well? appears to work fine off the car). Hooked it all up, and it does EXACTLY the same thing. The engine WILL NOT turn, i clearly hear the relay click and the solenoid hit and nothing happens. Im lost. The car was running fine prior to this, 

just checked the starter relay and its fine. This makes no sense, unless the engine is seized which also makes no sense cause it was working perfectly fine, it even started at one point when i first had the issue.

If it checked ok out of the car well probably
 
With regards to the  relay one of the wires has a fusible link close to the relay , you cant see it as its covered by loom tubing , could be its blown

yeh i checked that, only reason i havent looked into fuses is because when it started happening it was kinda intermittent. It would actually start cranking at the start, but really slow, then it would start doing this. 
 
Ill try another battery from another car again. It looks like a dead battery basically, but ive tried a few already lol

Try to get a multimeter on the lug on the starter while someone cranks the engine ?

yeh i can try that, see what happens. From what i see, it looks like the thing either is shooting out and cant turn the motor, or its not even shooting out.

If the bendix gear is broken or the teeth on the flywheel have been ground off, the starter will still spin. They take a lot to break and two aren't likely to break at the same time. The solenoid throws the big switch that allows high amperage straight through to the starter motor, without having that go through your ignition switch. Can you check to see that the motor will physically turn, pull on the fan belt, get on the end of the crank bolt? Loosen the plugs if that makes it easier. 

yeh the motor is not spinning at all, i got my dad to turn the key and had a better look and listen. Im not even sure if the gear is pushing out fully or not. Battery i can rule out for sure, just tested 2 good ones tonight.
 
I think i got another stuffed starter. So ill pull it out tomorrow and see if it will run without being against the engine, and ill rotate the motor too a little.

yup ill check that tonight because the only thing i can think of is that both starters i have are stuffed lol.
