Bought a 97 7.3 a month ago with a few known issues and have been working on it a bit here and there. Sort new to diesles but picking up a bunch of info. Recently replaces the Cps and another sensor that senses the oil pressure for the injectors. Was driving it last night and truck shur down like I turned the key. Sat there fiddling with it for hours and noticed tach isn't moving when cranking also noticed the wait to start light is not comming on. Read a bunch of forums that led me to check fuses all of which we're fine, checked all fuses with a meter. Not sure exactly where to start.
