New fuel pump and filter. Vehicle will crank reach idle rpm and die. When you turn the key on it will reach about 60 psi. After a couple of seconds it will drop to 55 psi. Sometimes it will hold for several min sometimes it will bleed off. I am new to these injection system. It definitely isn’t a carburetor. Any advice. I did read on a forum about a nut kit. The oil is magically a little high. I have to see how it smells tomorrow. Any help or advice as to where to start would be greatly appreciated
