    I have a 1995 F355 and it rarely starts on the first crank, but starts immediately on the second crank. Any suggestions?

    Again, try the search function, "Conscom" has an extensive thread on the subject, and thus far, has not found a resolution. Your title does not match with your description. It cranks, but does not fire on first cold start, yes? But second attempt it cranks and fires?

    You're obviously new here, so first one is on me ;)

    Seems to be both cold and warm. If I come back from a drive and let it sit for more than a few minutes, I deal with the same issue. It will sometimes sound like it is going to fire on the first turn of the key, but will fall off. 2nd try...no problem.

    I was wondering if I am not waiting long enough before I crank it...or if there were any other tricks I should know about.

    Thanks.

    Hmmmmm - ok, this is just a guess, but it sounds as if the fuel pressure is dropping after shut down - could be due to a leaking fuel pump check valve or leaking injector, or or or. On some systems, the fuel pump will only run for a few seconds if it dosent see the engine rpm up - a safety feature for car wreck. So the first time you crank over the motor, the pump pumps up the system somewhat but not enough to fire off the motor, the second time another burst of fuel pump, pressure up, and bingo. We have lift off. This situation is sometime aggravated with hot temps or high alcohol content. Let me know what you find when it gets to a point that you get it fixed. Thanks

    Thanks for the thoughts...I have it in FoA right now getting looked at. Hopefully I should know something soon.

    The registry was one of the first things I did when I got it...good to be part of the family!

    FoA thinks it needs a new fuel pump and relay. It is losing pressure when turned off, and the pressure valve (?) is part of the fuel pump.

    Go to your local auto store and buy a $2 can of starter fluid. Take said can to FoA and ask Chris if you can try starting your own car in the shop. Spray 2 seconds worth of starter fluid into your intake/air filters.

    At this point, does the car start up on 1st crank, yes or no? If "yes" with starter fluid, then you have a fuel pressure issue (could be a $60 fuel pressure valve, fuel check valve, fuel pump, or leaking fuel injector).

    If "no," your 355 won't start on the first try even with starter fluid, then you may have an alarm or other electrical gremlin (e.g. failing crank sensor or poor crank sensor connection or some such).

    There are additional tests to perform based on the "yes" or "no" above...complicated by the fact that your car is already in a shop...which can only make money by fixing cars *fast* rather than taking the time to diagnose to save you money. Not their fault...that's just economics.

    Anyway, I'd be testing/replacing the cheap parts before springing for a new fuel pump! A new fuel pump might seem to correct the problem, but a failing fuel pressure regulator will eventually bring the problem back if the FPR is the culprit.
