I went to start my truck and it wouldn't start, thought it might be the fuel pump because I had heard some unusual noises from it. Took off the fuel line going into the fuel rail and turned the key on, no fuel coming out. I also scanned the computer for error codes, it brought up PO320- ignition/ dist. Engine speed input circuit malfunction. What do you think?

The code refers to "no crank reference signal at PCM" Are you getting spark? Check the crank sensor wiring connector to make sure it is clean and tight. Let me know about the spark and what you find and then we'll move on to the fuel problem. This may be shutting down the fuel pump. Also, if you want, try switching the fuel pump relay with another relay from the car with the same part number to see if that changes things with the pump. Also, make sure the fuse is good and not blown.
