What El P is trying to say is that we need a bit more information. And to start to guide you, there is a simple test to check the ignitor. Remove the glow plug from the engine and gently put it in the ignitor. If it glows red, you're good. If it doesn't, there could be 3 possible problems. 1- dead ignitor. Charege it. 2- fried glow plug. Replace it. 3- plug is saturated with fuel due to flooding. Shake the fuel out of it and try the test again. If your plug glows, then both pieces are ok and there is another problem.
