try and push start it
probably flooded as hell

do not attempt to restab the CAS like that one idiot adviced. You will probably **** it up even more and that is one extra thing to troubleshoot.

Did it run before?

Start with the easy thing...
Is the AFM still good?
Is the gas good?
Are the plugs good?

Last thing you want to do is do something that you have no idea what you are doing.

The CAS does not change itself or decide to jump a tooth all of a sudden. If it wasn't touched, don't touch it.

Two ways of turning the engine over by hand: If the spark plugs are in it, it's easier to get a 19mm socket on the main crank pulley and turn it (don't worry, you won't put anywhere near enough pressure to tighten or loosen that bolt!). If the spark plugs are out, it should be easy enough to just grab a belt (Say, by the alternator) and just pull the belt, which will rotate the crank.

ok thanks and to slpin yes the gas is good i siphened out the old gas and put new gas in it and the plugs are brand new but i do not know the last time it ran because the previous owner said he never had it running he bought it to get runnin but wrecked his moms car and needed money to pay for the bills so he had to sell it before he had a chance to really work on it. and i will check the afm when i get back from my allergy shots :/ and we will also be towing it behind my friends truck to try and push start it so i hope this works

Do not tow it to push start it! When you drop the clutch the car will suddenly slow down, putting tension on tow straps which could pull something off. You really only need to get it moving maybe 5mph. Just get a buddy, you two push it down the road and when it gets going at a good clip, hop in, put the key to on, clutch in, put it in first, and drop the cluch. hopefully it will start. And make sure that when you turn it by hand, you turn it clockwise.

told ya push starting it is a good idea XD
effortless and it usually works - even if the motor is bad....
thats why i said restabbing the cas is pointless XD

now the fun and easy part like you said
the problems wil just show up... replace the obvious....
get a new thermostat too - from MAZDA....

can any one suggest a good place to find a radiator for this beast and would it be worth getting a performance radiator or just sticking to a stock one

Places like MAZDATRIX sell almost stock radiators for not toooo bad a price. Also KOYO are good radiators but cost more. I've two of those items.

Cuz overheating these engines is a sure fire way to kill them. Since the car has been sitting for who knows how long, its a good idea to replace the little simple things like hoses, belts, radiator caps, thermostat. So that if you do have a heat problem, you know its not the little stuff and or you have saved your engine from future failure replacing them.

haha i drove my fc wiothought a fan shroud for a while...

It's definitely nice having one.. if you have an aftermarket intake it helps cool it down... because if you don't have the fanshroud on it sucks in more hot air from the engine.

I'd put it back on if i were you..

and yeah

when it floods again...

pull the egi fuse like said crank for about 6 seconds or 8... and then do that three times...

after that put the fuse back in..

crank it over with no pressur on the throttle when it acts like it wants to start barly push on the gas and get it going like that slow and easy... lots of smoke and pops.. welcome to fc fireballs

another question that i have is would it be a good idea to trim the fanshroud on the bottom part towards bottom of car so that it clears the fan so i can take it off easily for more access to parts? otherwise it is a pain in the butt to try in get off. i am asking all these questions so that my ideas dont end up being costly mistakes.

No, keep it as it is. The whole point of the thing is that it directs the pull of the air from the fan, so that the fan is efficiently pulling air through the radiator, not from around the engine bay. Is removing the fan that big of a deal? It's four nuts. Try dropping a transmission....

You broke an inch off one of the fan blades. That will destroy the fan clutch assy if the fan is allowed to spin like that for a given length of time. As in ...unbalanced/out of balance.

that sounds like alot of useless work to me trying to add the weight back to the fan... if you want to be ghet about it just for now you could gorrilla glue it on there i suppose...

if you didn't live in kansas i would pick you up a fan from the junk yard today since i'm going anywho..

but i think it should be fine withouth that piece for a bit.. not too long though make sure you get a fan soon!

well actually it was really easy adding the weight back on i just used a scientific scale weighed the piece that broke off then found a bolt and set of nuts and washers that weighed the same amount and put a small hole in the fin that the piece broke off and put it on there making sure it was even amount of nuts and washers on both sides i figured it would be at least a little stronger than gorilla glue
