The main relay needs to be replaced.

 

Main Relay.

------------------------
Temporarily, you car will run if you turn the key to II, smack the dash
hard with your fist, (fuel pump runs a few seconds) then start the car.
The vibration makes the relay start, and the engine running makes it
keep going.
