You need to hook up a fuel pressure gauge and check pressure. they cost40 bucks at oreillys/autozone and they can tell you what your pressure should be. You have 1 pump per fuel tank and they are in the tank. Do you hear the pump come on when you turn on the key? it might be a fuse. Could be the fuel pressure regulator pull the vac hose off of it if there is fuel in the vac line it is bad. Also GM has a problem with theft passlock shutting off the fuel. Are you using a key that came with the truck, walmart made or others will not allow fuel. If you have a good key try this it is free Put your key in turn it on dont start wait 10 mins remove key wait 10 seconds repeat this a total of 3 times. If that dont work try a different key do the same thing. If that dont work a dealer needs to probably replace and reprogram your ignition switch and keys. This relearns your key and allows fuel to come on. Please comment back I am curious as to what you find

Knock sensors as a rule of thumb are positioned right beside a piston on the the block. It should be on the opposite side of the exhaust system. A knock sensor is actually a sensitive microphone or listening device. It listens to a piston performance under load. If it hears a knocking or pinging sound it will ****** the ignition timing and advance it again when condition changes. It would have a securing bolt in the middle which torqued to a certain spec and a single wire harness.
