Problem. Glow Plugs? Relay? Something else?
I'm not much of a motor head. I guess I know just enough to be dangerous. So, I thought I would seek help here.
I have a 1996 F-350 crew cab, 7.3 Power Stroke. Since last fall I have developed a starting problem. I always plug in my truck in cold weather. This spring I have developed a problem starting in weather that wasn't a problem last fall. Even in 60 degree weather, unless my truck is plugged in, it will not start. I will cycle the glow plugs. When I try to start it, the engine will continuously turn over and exhaust will start to pour out of the engine and into the cab. However, if I have it plugged in, irrespective of outside temperature, it will fire up every time. I first made the assumption that I need new glow plugs. Someone then told me I may just need a new glow plug relay. I hope I have provided enough information. Your thoughts? Thanks in advance.

Welcome to the forum! T think you are on the right track. A quick , cheap test-- with a test light with the wire hooked to the battery ground, you should get a light when you touch one large terminal on the glow plug relay regaurdless if the key is on or off. Turn the key to th on position and check to see if you have a light on both large terminals.If you get a light on both terminals the relay is activating. A multi meter would be better if you have one. You should get 12.5 volts on one terminal, and no more than 1.5 volts loss on the other when the key is in the on position.
You can also "jump" the two large terminals with a screw driver for 30-40 seconds, just be very careful not to touch any other metal with the screw driver, or you will get big sparks. LOL If it starts after jumping the relay, you have found your problem.
