The "D" fuse in the fuse box did not look to good and I have changed it as well this morning, is that the fuse for the GP relay? I have lost the paper from the back of the cover with the fuse info on it.
The fuse for the relay is located on the relay itself, under the cover towards the front/lower end. its about an inch and a half long and is held in place by a visible screw at each end. Even if it appears to be intact, it can have microscopic cracks in it that will impair performance.

The full cycle for the gp's is to engage when you turn the key to the on position and disengage after either the set time, approximately 40 seconds, or the engagement of the starter. The dash light time will vary depending on ambient and engine temps and is really more of a guideline. It wouldn't hurt anything to wait a couple of extra seconds after the light goes out, as the gp's should still be engaged.

Yes, an afterglow relay will keep the plugs energized after the engagement of the starter, whereas a standard relay will cut the plugs out as soon as you turn the engine over.
