How to glow the engine when slightly warm?
I have a 93 chevy 6.5. The glow plugs work great when the engine is dead cold. The engine fires right up on what seems to be a quarter of a revolution with no smoke and no missing. But If I drive a couple of blocks and shut off the engine, the glow plugs will not come on and the engine has to crank about 5 seconds to fire up. What do I need to do to make them come on when the engine is past the dead cold stage?
