Mmm... I'm hungry all of a sudden. to check your glow plug unscrew it from the engine and attach it to the glow charger. If the coil lights up then it's fine and you just have to tune your car. If nothing happens then you'll need a new one. Be real careful though, that thing gets real hot and will easily burn you if you're holding it in the wrong spot. Also be sure you have somewhere to pop it out of the charger that isn't going to burn. If none of that works let us know and we'll try to think of somthing else
