    Seems be happening every few months now that I go to start my truck (2009 TRD) and it just wont start. Battery is brand new, starter cranks good, but engine just wont fire up. After a few seconds I turn back the key, give it a few seconds to rest (just seems like the right thing to do ??) try again and it usually fires up on the second attempt.... sometimes the third. It never happens twice in one day... it has happened in every season warm and cold, but never when its still warm from running.

    Any ideas what on earth is going on????

    Thanks.

    Does this happen when it is really cold? My truck usually starts after 3 cranks always, but one time it got really cold, below zero I think and it took a little more cranking to start. How many miles are on it? What spark plugs do you use, and how many miles are on them?

    My truck does the same thing, only after sitting overnight or for several hours.
    It has done this about 2 times over the last 4 months. It seems like it will start then shuts off. When I try again to start, it cranks quite a bit before starting. I have tried staybl and fuel system cleaners as this happens in the cold temps. The both times it happened after filling the tank with Mobil gas? Next time in for an oil change I will see if the dealer can pull any codes.

    I just read this, sounds interesting.

    Here's my put on this. My 2010 has had similar issues. Not as bad, but it has happened. After starting and running my rig in the morning and parking it at work I noticed the hard start issue. Actually thought I was gonna flood it a few times. I posted and got a pretty advice that seemed to help. It seems that when you start your rig if your like me you put the key in an immediately turn it over. Someone suggested that because the Taco's has electric fuel pumps you might want to wait a couple of seconds before turning the truck on. The suggestion was to let the door chime a couple of times before turning it over. This gives the fuel pump a chance to prime.
    All I can say is when I have done this I have had less issues. Give it a shot before going all out. Never know.

    ^^^ good info. I usually let it sit "on" not started for a few seconds before starting it. Have never had that problem, even with a vancouver truck. Have had some problems tho with my dads 08' accord starting lately. Maybe better spark plugs?

    Nice vette rdrnr

    Turn the key to the "ON" position for a couple seconds before you crank it. That lets the fuel pump prime and build fuel pressure. I used to do this when I drove a turbo car with a bigger fuel pump and modified fuel maps so it became habit. I do it to every vehicle I drive now.

    I reliably have hard starts when I get gas from a different station than usual. I don't know if the gas is bad or if the engine just doesn't like it as much, but the 3 times it's done it have all been a couple days after filling up at the BP station down the street instead of the Exxon I usually go to.
