  1. I have had, what I thought was a "cold start" issue with my 91 LS400. I've tested many of those components and all is well.

    I now believe it is a fuel issue. Here is the deal:

    The time it takes to crank seems to be related to the amount of time the car has been sitting.

    Example:

    If the car sets overnight, it takes about 3-4 secs to start in the morning.

    If the car sets several days, it might take 6 secs to start the next time.

    Once you start it, for the first time in the morning, you can immediatly kill the engine and it will start immediately all subsequent times.

    It seems as though the fuel system, very slowly looses pressure over time, as the car sits. There is no gas visibly leaking under the car. The only other thing I noticed is that the evap canister is rusting and it smell like gas. I'm not sure if that could have anything to do with it.

    Anyone have a clue? I don't think the injectors are leaking. Is this something I can test? Does the fuel system stay pressurized when the engine is off?

    Thanks,

    CL

    just a test :D
