The opposite. The problem is the main relay. I was explaining how and why it's doing it in a confusing guru term.
Let's explain again. The residual fuel pressure (the quantity left over at the end of a process) (not residue) is still in the fuel rail the last time the main relay worked. (Keep in mind that the main relay controls all the fuel supply.) But if the main relay doesn't work anymore the car will start then quickly dies (like as in start then rpm shoots up to 1500 then dies.) This is a main relay symptom.
By tapping or banging on the main relay the vibrations will make the main relay work. This is your diagnose.
