My glowpugs are acting up. They work fine for the inital start, but if the engine dies, they only come back on for a second then it's hard to start. Even after driving it, if I let it sit for a couple hours they wont come on at all. They only come on when the engine is totally cold. These engines are very hard to start even on a warm day if the glow plugs aren't working.
