2002 f350 7.3 won't start.

Need some help... I was replacing my glow plug relay today, and somehow i shorted the big terminal on the relay to the small post that sits in the front of the relay. <accidentally laid a screw driver across them>.
The truck cranks but won't start now, the relay for the injector driver module chatters. I replace that module and still chatters .. The glow plug light on the dash stays on and never go's out...

I hooked up my Diablo tester and it doesn't read any codes at all,<says"unable to detect> from the ECU or PCM <if theres a difference between them> .Thinking the ecu/pcm might be fried now. And i checked all the fuses..

Would appreciate any help .. thank you

First, when you turn the key on - Do you get a Wait To Start light?

all the fuses? even the ones under the hood?

Electrical problems = Kryptonite

Sorry dude, good luck.

On this diesel only thing on the dash is a squiggly coil indicator for the glow plug, it used to stay on and go off when the key was turned on, Now it stays on . And where would the fuses be under the hood? thxs'

This is a Super duty right? If so there is a black box that sits right behind the air box with a lid on it. pull the lid off. I am not familier with the code reader you have. But in some readers they get power from the OBD2 port to read codes. And if there is no power there it will not work. That circuit is the same as the ciglighter.

behind the air filter box, the only thing i could see where 2 small black boxes, in them were relays, 2 in one box and 3 in the other. Just wondering if there are any fuse links that could have burned ?. and yes sorry, this is a superduty 4x4.

There is a fues block on my truck any way with fuses in it right behind air box. the box is about 4" X 6"

FIXED!, ......i decided to go back and recheck all the fuses again.fuse #22 "engine control" i noticed this time it was bright on one side with test light, and the other side wasn't so bright.. so i pull it and lo and behold, it was almost burnt in two. But just had enuf holding it together to get a light from it..<or reading>.. And i appreciate everyone help sincerely.
