Rite..cud b relay or pump is faulty or connection. Turn key on n off threetimes..on four try startn..if goes then the residual circuit is not holding fuel and the checkvalve or pump is issue

One check you can do is open the fuel cap see if you hear air rushing in when you open it. If so try starting the engine with the fuel filler cap removed if it starts this indicates the filler cap is blocked and either needs cleaning out or replacing. This causes a vacuum in the tank that will starve the engine Also if there is a fuel filter in the system this should be checked/replaced if filter is full of debris then it would be an idea to have the whole fuel system and tank cleaned out. Often with older cars and especially ones that may have been filled from cans in the past if allowed to run too low on fuel will pick up debris from the bottom of the tank.thy these first before outlay on a new pump to test fuel to the engine. Remove or loosen a fuel line from an injector and see if fuel is present when turning the engine. If so then fuel is not the issue. Hope this is useful.
