Any applicable codes? Can you hear the fuel pump run when first turn the key on, no crank? Can you check for rpm signal? Battery has a full charge, all connections clean and tight. Did you check for voltage anywhere?

Check ecm B fuse, 20 amp, underhood fuse block. Not only check the fuse, check voltage at fuse circuit.
With key on, do you have ref voltage at the tps, or any sensor that uses a ref voltage? I just thought the tps might be the easiest to get at. I'm not sure of engine litre size?
