WTS light/glow plug challenge!

Let me preface this by saying I recently had a head gasket replaced and my WTS light worked correctly beforehand. I also had no issue starting the truck when it was cool outside. Now, I have no WTS light, the truck won't start without ether and there is a rapid clicking from the glow plug relay. So ... bad glow plugs right? nope. I replaced all 8 with Motorcraft plugs. Nothing changed. So.... bad glow plug relay or controller right? nope. I bought both new and still having the same issues. It is wired correctly and my ground is good. What else could this be? I have searched high and low and 9 out of 10 times its the gp's or gpr/ gpr ground. The GPR clicks pretty fast like its not getting resistance at all. Could bad gp connectors do this? mine are pretty rough but like I said it worked before. thanks for your input fellas

I realize you are new, So Welcome to FTE ...

Please do not cross post though, You have the same thread in the Pre-Power Stroke Diesel (7.3L IDI & 6.9L) Diesel Topics Only forum. and is actually the better place.

However, Either will get you the same results as the same Diesel folks that hang out here also hang out there.

I have responded there ...

-Enjoy
