GLOWPLUG RELAY?

[Oilslinger]

WELL mother nature is teaching me a lesson about the cold and diesels. I 'm in the process of gettin manual for truck. Till then I need help, which solinoid is the GPR. Truck starts very hard in morning. No smoke on first 2 cycles, then smoke , then a sputter,once she has fire in her no problems for the rest of the day. If she sits over night for more than 10 hrs, she's a bear to start!Plugging block heater in doesn't seem to make a difference! I've only owned it 5 months . First 3 months lift pump would come on when cycling glow and would go off around the same time too! Now I hear it come on and stay on?I do have antigel additive in fuel. HELP! Any suggetions for debugging are greatly appreciated

The glow plug relay is the shorter one in the rear of the two. The tall one is the relay for the intake heater. The glow plug relay is a fairly common failure item. Do not buy one from ford. It will cost you almost $100 and it is no better than one you can buy from Napa for $35.
