three thing make an engine run---air---fuel---spark any one of these are missing---engine will not run---if you have a timing belt, it may have give up the ghost but you need to check these things out to determine the issue---no magic wand here just facts---GL
pour 3/4 of ii into your oil and the remaining into your gas tank...then drive it for one week then change your oil and your engine block and fuel system will be clean and like it was when it was new
run hot even at highway speed? no leaks, or sweet smell? ever have to top off coolant? ever boils out of system? if no to all these, sounds like your cooling fans aren't working. there is a fuse either on the motor cradle or on the passanger side wheel well. start the car, let it warm up, and check for power to the cooling fans.
