This is what a burnt out GPR looks like

[torq]

I was having trouble starting in the mornings and finally nailed it down to a bad glow plug relay. The GPR was either not putting any current through at all or I was getting extremely hot - hot enough to melt latex gloves.

I did Guzzle's awesome Stancor relay upgrade and I now actually look forward to morning starts. Welcome to guzzle's Stancor GPR replacement Mod Web Page

I ground off the rivets on the old relay and tore it open. The relay design is unimpressive compared to heavier starter relays I've seen. The plate on the left is flipped over and is pushed down onto the two contacts on left and right at the bottom of the bowl. The plate and the contact points are trashed from arcing. The top and bottom points are the activating circuit which is not looking healthy either.

Thanks for the advice on the Stancore relacement GPR Im a little green with my 2001 7.3 But learning alot from u guys out there. Up graded 2 a MBRP 4in. Exaust, S&B cold air intake, Gauge kit. Diablo sport programmer. What a difference! Did just put the Stancore GPR in. The job was easy as stated. My truck has 157,000 on it.
