Functional glow plugs "required" to start truck?
I am trying to diagnose an issue where my truck will crank but not start. It is not CPS. When I turn the key to RUN I know it will _not_ start if the CEL and glow plug lights stay on and the Water in Fuel light doesn't come on. If the Water in Fuel light comes on (and clears) and the glow plug light extinguishes normally then the engine _will_ start.
It is not a cold starting problem... the weather is 75-85 degrees and _no_ fuel is being delivered when it won't start. I replaced the glow plug relay today and the issue seems to have gone away... will any of the possible failures of the GPR cause the computer to cut fuel? Does the computer require a functional GPR to deliver fuel?
