Ok guys, First or second post here. Whats up! I need some help please!

If you turn the key 1->2->3 quickly the starter engages and tries to turn the motor over. You can physically see the timing belt move about an inch or two then the car stops. If you go 1->2......->3 you get nothing. You have to sneak up on it to trick the car to start for half a second.

Here's what I have checked
*Starter (Bench tested, fine)
*Alternator (Bench tested, bad diode, replaced)
*Battery changed with a fully charged working one out of a working car every time I test it
*Terminal connections and all other connections-to starter- alternator- etc... Checked and cleaned with sandpaper.
*Fuses and relays checked (They all click when 12v supply is added)
*2 10A fuses blown (Highbeams and interior lights or something useless like that)
*Car internal lights turn on, a lot of warning lights are on like oil, red car with an X through it, battery, CEL, etc...

I hooked an OBD2 scanner up to it and got an incomplete for
-Misfire monitor
-Fuel System
-Comp component
-Catalyst mon
-Evap system
-Oxy sensor

I feel as though these aren't related to my problem though, there is no way all of these things can fail at once.

Before I changed out the alternator the car would only click occasionally, now it tries to turn the motor and it does turn it for a very small amount. I need some help on this one guys.

Thanks for the help!
