Answers :

With a Diesel there are additional parts that you have which affect the Cold start. There is a timer between the glowplugs and the Power relay on the start circuit. The timer cycles the glowplugs off/on for a variable time period. The more cold, the longer the cycle period.
Glowplugs go bad. You remove them like sparkplugs. Testing them is a matter of comparison. When power is applied they can melt, so test with care. Hook battery jump cables to each glowplug taking care to attach one lead to the base (avoiding the threads) and then briefly touch the top of the glowplug.
The quicker the plug glows, the better it is. The darker, the worse it is.
But the timer must provide the juice to the glowplug for it to work. A bad timer will not properly heat the glowplugs. The timer must get its' power from the Power relay. So you can have acceptable glowplugs, and a bad timer.
Ultimately once the engine cylinders have run hot enough, a Diesel fires by compression and not by spark as a gas motor does. That is why once you have a hot diesel, it will start freely.
It is why I explained the needs of a Cold Diesel engine and I hope this helps you.
