I have a 2008 pontiac g6 sedan 2.4L recently she craped out on me but the fuel pump runs and the engine cranks over wonderfully I purchased a fuel pump assembly thinking it could be the fuel regulator on the housing i havent gotten to replace it yet but I have no idea where else to begin troubleshooting. Advice would be greatly appreciated Thanks you.

Have you done a fuel pressure test?
Have you tested for spark?
Have you checked for codes?
Before it failed to start did you hear any rattling noise when starting or at idle?

Normally, key on, engine off, to read codes.

The key has to be on to check for codes.
Either you have to look online how to run those tests or have a mechanic come to you or tow it.
You may want to do a compression test also due to the white smoke.

fuel test is good 50-60psi
I tried to read the codes with a cheap reader but it didn't work so ill get them read soon.
once the things come in ill test for spark and compression

What happened to checking for codes and a compression test?
