Cobalt fuel pumps?
 

A buddy of mine As a 2001 cobalt 262 It has 496 mag HO Said I don't find out around the dock shed it off to go get the trailer in the truck And would not start again I don't know much about the 496 Mag HO if they have electric fuel pumps for mechanical fuel pumps and where they're located on the motor Or is it in line down by the fuel tank? Or I hear those motors are very finicky with relays Any help to pass on to him would be appreciated thanks
