09chev Malibu changed my fuel pump now car won't start. I can hear the fuel pump turn on, there's fuel going to the engine, I get good spark. My car cranks turns over then shuts right off in 1-2 secs.
Check the fuel pressure regulator.
How much pressure should it read
Different pressures for different vehicles do not know all of them you will have to check in a repair manual or a parts store may let you look in one of there manuals.
