2001 Ford F350 7.3L DI Glow PLug Problem/Leaking Diesel

Problem: Truck does not start very well when cold outside. Glow plug relay replaced, but does not activate when wait to start is lit. Relay was replaced no change in behavior.

The relay post closes to valve cover gets 12 volts, when key is turned both of the smaller posts get voltage. The other large post has 0 voltage. The only way to activate the relay is ground the small post closest to the cab, then the relay clicks and voltage flows...

I heard that I might have a bad crank sensor, bad ECM (the ecm has no codes when I use my obd II scanner), may be a bad ground wire???

The truck runs perfect when warm. The other issue I have is randomly diesel start leaking from engine down the bellhousing, on the starter side. What ta heck can that be?

Any help would be greatly appreciated.

not sure about the glow plug problem but for the fuel leak you may look at your filter housing. the fuel drain (the black dealy on the fuel canister with the yellow valve) has two little o rings behind it that flatten out or leak due to the non lubricity of this crap they call ulsd. it tends to eat o rings like injectors and any other orings in the fuel system. its a fairly common leaking point on these trucks. you need to add like a cetaine booster or injector cleaner to your fuel when you fill up. helps to prevent that. so i hope that helps a little bit.
