Today when I got to a friends home after driving my cobra kinda hard on the way there I noticed it was hot a little to where the coolant was coming out the overflow. Upon further investigation I noticed the fan was not coming on as it should when hot so we put in a new cooling fan relay. Did no good. Fan still didnt work! All the while it had been cooling down while we put in new relay so we decided to straight wire the fan to the battery, well it worked fine then but made rubbing noise like something was caught in it. Upon closer looking I found the layer of watever kind of material that comes around the hoses had somhow came aloose and fot caught in the fan a little. I removed but fan still would not come on properly. I am wondering what would cause this?

A tight or locked-up electric motor will draw higher current than normal and usually blow a fuse. I'm not sure what your car uses for a fuse device but you can verify it is blown, (or that the high-current part of the circuit is okay), you can jump that relay or you can remove its cover and squeeze the contact to see if the fan runs. If it does not, check the fuses first.

Does the cooling fans (one or both) come on when you turn on the air conditioning on cold (key on engine running)?
Do you run an original equipment thermostat?
Any check engine light or service engine soon illuminated?
There are the three fuses related to the cooling system no blown or in other words open circuited (fuse #1 is 50A fuse fuse #26 30a under hood fuse box Fuse #34 20a fuse box behind driver side dash box left of the steering column)?
