A quick check on the fuel pump relay is to pull the relay out [ bit of a job ] they can be tight in the holder .Hold the relay in your hand , and then pins 7 and 8 you wire them together, push relay back in to the holder .. Only use the wire to see if it is the relay or not . Once you prove its the relay ...thats if engine keep running , remove wire right away and replace the relay with a new one .
