stalling at ignition

    if the car (honda accord ex 1993) stalls at ignition or
    turns forever, what can that be? I've tried looking at the main relay,
    it seems ok. Hotter weather the car is worse off, especially
    with humidity. If I throw it into neutral then back to
    park I also have better 'luck'.

    PS- thanks for the advice from last time. My new server
    only allows two days then makes the messages 'illegal'.

  2. I advise you to do a complete tune-up. It could be something else. I don't
    know what you mean when you said that you "tried looking at the main
    relay--it seems ok." The only way to detemine if the main relay is working
    is to test it with the proper equipment. If you don't have the proper
    equipment or know how to test it--I advise you to take it to your favorite
    mechanic and have them do it. If you want to do it yourself, you need to
    get a manual such as one made by Haynes. Try calling Haynes at
    1-805-498-6703. The one you need is 42012

    The factory service manual can be obtained from
    While it may be slightly more expensive than a Haynes manual, it will also
    go into much greater depth.

    Well,the main relay activates the fuel pump(if the MR is working)."looking
    at it,it seems OK" is not going to tell you if it -is- OK or not.

    This tells you how to FIX the relay and eliminate it as a potential

    Or you can spend $50 (or more) and replace it.

    Then it could also be a worn ignition switch.

    Ok thank guys. I'll probably just buy a new main relay.

    Well it appears that when i turn on the preiginition; I see the
    check engine light on , i also hear the fuel pump turn on. This
    only happens initially. After I have it running and try it again
    only the check engine light goes on. The fuel pump doesn't seem to
    engage and the car doesn't start. Though it only started once when
    it was in neutral. Could this tstill be the main relay? The check
    engine light never really stayed on for a long time until only
    recently only after I had my brakes done.

    Also, if I try to get a honda diagnostic setting I get a 'constant'
    check engine light. Does appear to have a corresponding id to a
    part or system.

    I also had the fuel pump replaced by a shop, only to have this
    condition carry on.

    If the engine actually fires and runs while you are cranking it, then stops
    the instant you release the key to the run position, the problem is most
    likely the ignition switch.

    Not exactly sure if it does that or not. I know that when I try
    to start it it will fire then die in the span or time while still
    turning the ignition.
    The question is, why does the fuel pump not engage (after it warms
    up) like it does in initial rounds of firing? Where can I get
    information on the fuel pump relay online.
    Searching stuff with google and altavista only brings up add
    web sites. Searching for information on automobile repairs
    is terrible on the web!

    The fuel system holds enough pressure for the car to briefly start,but not
    enough to maintain running unless the fuel pump keeps the pressure up.
    The solder problem on the relay PCB makes it -intermittent-,which is why it
    works sometimes,but especially not when its hot out.

    In all the time you've spent on these posts,you could have resoldered the
    relay and discovered if it was the problem or not.

    It could very well be the engine's ECU

    Humidity effecting the resonse of electric signals is common problem
    in a computer
    Especially one that was sealed in a box, and over time the seals
    are starting to deteriorate

    Best of Luck
