Just bought an 86 13b n/a for $600 and need some help

[88mike]

I'm new to this forum and a rotary motor but i recently bought a 86 n/a 13b that runs and drives for $600 last friday. It needs a few kinks worked out and was hoping to get some help. I was going down the road the other day and i noticed the add coolant light was on and i pulled in at th next gas station to add some and i was running a little hotter than usual. So i go in to buy some anitfreeze and as my luck would hae it they just so happened to be out and wouldnt let me use there water hose. so i figured i could make i to the next gas station about 2 blocks down the road and thecar would turn over but wouldnt crank. i finally got it started and got goin down the road and the light came on again i checked thetemp gauge again and i immediatly shut the car off. it wasn't but about a quarter of the way from the top of the gauge but i've dealt with factoy temp gauges in the past and i dont trust them anymore. well i checked the radiator and it had puked all the antifreeze and water out the over flow tank. so i started checking the entire coolat system ireplace the thermostat checked the water pump and its still good the radiator checked out fine along with all the hoses. and it's still some how puking all the antifreeze and water out the over flow for some dang reason and running hot. it's also got some flooding problems from time to time but i pull a fuseunder the hood i think its the egi fuse nt for pos what its called but it will hit a lil bit but still wont crank. i've changed the plugs plug and plug wires had the coils checked out and played with the distributor but nothing has really helped crank it. it also back fires between shifts when i shift on or before 4 grand. i'm leaving for basic in aug and then theres an 90% chance i'll beging to afghanistan shortly after basic and ait so i would like to have he car running before i leave. I would appreciate ay help or ideas you have.
