New Stancor GPR, But Still Problems

[Sculpin]

I just replaced the glow plug relay with the Stancor 586-902, but I don't think that was my problem to begin with. The problem I had was hard to start when cold in the morning only and also I've been noticing that the glow plugs aren't cycling like they used to.

I recall some years back hearing a slight clicking noise and the voltmeter slightly ticking for about 60 seconds or so, but that's not happening now. All fuses are OK. Is there a controller problem that's a relatively easy DIY fix? Is it something I can diagnose myself?

Thanks!

It sounds like you need to check your voltages to the relay along with checking the resistance of the glow plugs. With the key off you should only have power to one of the large post of the relay. With the key on you should have voltage to both large lugs of the relay and battery voltage to one side of the relay. Then once the relay shuts off you should have battery voltage to both small lugs and only one large lug. As far as checking the plugs you'll need a digital vom. Unplug one of the plugs on the valve cover (there are two of them) and you'll see 5 pins. The glow plugs are the outside pins on each plug. The plugs should read between 1 and 6 ohms to be good.
