If the vehicle is hard to start after setting overnight, the problem could be the fuel pressure regulator has failed and is allowing the fuel pressure to bleed off. A failed fuel pressure regulator will should be replaced.

    After sitting overnight engine floods and will not crank without removing plugs and drying them, this only happens once or twice a week. Also using excessive gas.

    engine hesitates to crank or takes to many turns to start the car. Once you drive the car come back and let it sit, try to start it again and it takes a few times before it does decide to start

    Car would have a problem starting 1st try 1/10 times when got it at 51k miles in 2007. No big deal, just prime it and it starts, right? Now it is long crank hard start every time but no problem once running.

    Code po 301 random multiple misfires is the check engine light I have.

    It takes several primes and cranks to finally get started.

    Haven't had money to fix.

    Looks like from research its the fuel pressure regulator in the fuel pump assembly. There's a TSB on this and people have continueing problems after shelling out 250 to $300+ on just a fuel pressure regulator or the whole fuel pump assembly or people going through multiple fuel pump failures.

    Same as above. When letting the car sit for any length of time, it will turn over for several seconds before starting.
