And in fact it won't. Here is a short list of what the PCM has no clue about: Fuel filter, fuel pump, fuel lines, fuel injector spray pattern, clogged fuel injectors, failing fuel injectors (it knows if it fired the injector, but it doesn't know if that event went well), fuel pressure, fuel leaks, grade of fuel, if water is in the fuel (the diesels know this, but not the gassers, AFAIK) or if the fuel is even capable of igniting, as in, varnished or aged.
Um, yeah, except the problem YOU mentioned first was a failed fuel pump, which is not monitored. This is directly related to fuel PRESSURE, which is not monitored. Further, if it was enough to get the truck going, but not enough to properly spray from the injector, there would be an atomization problem, which is not monitored.
Its absolutely correct. The only thing the PCM knows about the fuel is injector timing and A/F mixture via sensors.
Nah, I just jump on you for crap where you are wrong.
