    Fuel pressure is fine, so the regulator isn't your problem.

    So does the car start right up after it stops running? If not, you could squirt some starter fluid into the air cleaner---if the engine kicks off for a second, then you know you have a fuel delivery problem.

    the only way to deal with intermittent problems is to test right at the moment of failure--so when the truck stops, you need to test for spark (using a simple spark tester) , for injector pulse (using a NOID light) and for fuel (using the squirt test).

    Right now you're just guessing, which is okay, but expensive.

    Also, what kind of scanner are you using. Some of the cheaper hand-held scanners might not be good enough to read everything.

    Car will start back up after a couple minutes but not right away.

    The check engine light does not come on at all so no engine failure codes available.

    You didn't mention if you replaced the fuel filter or not, but you should really start there.

    What year?

    This is a 2005 Chevy Malibu and it does not have a fuel filter but your right I went to the dealer to buy one and they did not have one. The cannot get me in until Monday, which is a problem for work of course.

    Thanks

    FUEL STRAINER

    The fuel strainer attaches to the lower end of the fuel sender. The fuel strainer is made of woven plastic. The functions of the fuel strainer are to filter contaminants and to wick fuel. The fuel strainer is self-cleaning and normally requires no maintenance. Fuel stoppage at this point indicates that the fuel tank contains an abnormal amount of sediment or water.
