might not have the cor wired up correctly when it comes to that last red wire that needs to go two places right now i have it connected in the mr2 boot to a red wire with silver dots and then i have it extended also onto a plug on the 4th ecu

Follow this as a test, link the thick black and white wires together on your starter relay, let us know if the starter turns over.
Check your engine actually turns by hand, a common homebuilders mistake is to use too long a flywheel bolt or front torque mount bolt jamming the flywheel.
There's a lot of explanation for what could be wrong but the circuit and wiring is very easy to diagnose.

The starter circuit is VERY simple, refer back to the wiring guide. If you have the GREEN starter relay in the boot, you should have used that. If it's missing then i'm guessing thats why the Bosch relay is in there.
If you check and correct the starter wiring (as per the wiring guide) and test. Please be sure to check everything carefully, it is very easy to make a costly mistake, which is one of the reasons Paul Woods pulled the wiring guide off the forum. Double checking things might seem tedious, but very important.
If you post up any pics (or video!) on this thread it will make it easier for people to help.
** Also bare wires are not good. If it isnt used, cap it with a bit of insulating tape.

also when it comes to wiring up he fuse box i have it wired up with all three thick white cables
okay, just emailed you a link to the revised wiring guide (v1.6) that Paul Woods was kind enough to let me update a couple of years ago. It has some additional pictures etc so might help clarify.
Post up any questions. The worst we can do is point and laugh. :)

i just tried to test by attaching the thick white to the thick black and nothing happened it didnt try to crank im not sure if it has anything to do with that loose red wire but anyway i think im getting power to the fuse box because when i ground the black and white wire the temp guage shoots all the way to hot
i think it might have to do with that last red wire that has to go two places but for me its a black wire, also got confused on the part with the black and yellow wires i saw 2 so i just used them both right now i have it connected to a red wire with silver dots that was left over from the mr2 5sfe harness in the boot
I don't mean to sound negative but your posts are nigh on unreadable, I just can't decipher what you are saying about the issue and you're joining wires up all over the place!
Step back and follow the advice being given, simple tests and don't do anything rash.
If you joined the black and white together and no cranking then you need to test the white wire has 12v on it, and test the black/white goes to the starter solenoid.
Also did you check the engine actually turns by hand as advised???

Is it just me or does it not look like he has the main battery to starter wire
