ok so heres a stupid question. i took my truck to a shop for a diagnosis problem. the mechanic told me my fuel pump is bad and im not holding pressure in my fuel lines. could this be something as stupid as a loose old cracked gas cap? or should i just do the fuel pump?

Have the fuel pressure check to rule out the fuel pump

A defective gas cap won't cause a low fuel pressure
