Ah, Ok the issue here isn't the GP relay at all most likely. The glow
plug system and the starter are mostly independent. One will function if
the other is faulty, and neither can bring the other one down.
Your problem is, in order of likleyhood:
1. Bad ground at the Battery, chassis
Check the starter solenoid wire on the firewall, it's a purple wire
going to a jumper block below the battery if I remember correctly.
It's common for the connection to corrode, giving you intermittent
starter operation.
Loose engine ground and ignition switch are the two common things

I'd try a new or used relay. A bad relay can run down the battery.
Used relays can be pretty cheap.
