how can I tell if the computer (PCM) is bad
what the title says
my truck has no spark and the rpms do not register when cranking the truck so I replaced the Crank sensor and still the same thing, I know fuel is going to the cylinders but the thing is just not sparking and it I am almost positive it is not the coil packs because they could not have gone out overnight(literally)
but anyways since I am almost sure it is the computer (unless there is a relay) how can I tell if it is really that without buying a new one

SUCCESS!!!!
turns out it was that fuse...man that sucks that my truck was brought down by something smaller than a nickle
however my truck still does not start up immediately when I turn the key what happens is the starter relay clicks but the starter does not turn I may need to pull my starter and clean it(it looks to have a lot of oil on it) and hopefully that will solve my problem
