    I'm working on my buddy’s civic and having some trouble figuring what’s
    wrong. The car was running ok until he came out of the store and it
    wouldn’t start. After having it towed to my house I started to check
    things over. His mechanic said it was the timing belt. Sounds like all
    mechanics. I pulled the distributor and tried to start the motor to see if
    the rotor turned. It did. I’m guessing that the timing belt is ok. I pulled
    the spark plug to check for spark. I got spark. I checked the fuel pump
    inside the gas tank and can hear it running. I checked the fuel lines
    coming into the manifold for flow and pressure, Its OK. I finally read the
    codes off the computer. I got a #16) fuel injector system & #17) VSS
    error code. Now the kicker is when I try to start the car it just turns
    and turns. Now if I pump the gas pedal as fast as I can the motor all but
    starts. As soon as I stop pumping, the engine dies. I then put some gas
    into the carburetor and tried starting the motor, no luck with that. This
    91 civic hatchback DX has about 160,000 mile and the 91 model has a PGM-FI
    system on it. Any Ideals……..

    Dunno about the codes (engine flooded now?) but based on a lot of
    reading here and experience with my own 1991 Civic LX sedan, the
    leading causes of early 1990s Civics not starting (but the distributor
    rotor turns) are:

    1.
    Failed distributor ignitor. How old is the current one? They last
    maybe 100k miles. The following sites are helpful on the subject:

    http://www.markl.f9.co.uk/howto/electrical/igniter/igniter.htm

    www.autozone.com click on the links to the free repair guides. Put in
    your car's info. Go to engine electrical, distributor, etc. for some
    checks you can do on the ignitor.

    2.
    Failed main relay. But you say you hear the fuel pump running, so I'd
    lean towards 1. Also, it's usually an intermittent problem: The car is
    drivine for awhile, stopped, then won't start for awhile, then after
    sitting it will start.

    Updates welcome, for the archives.

    Good luck.


    (Carburetor and PGM-FI? That's a post-o, isn't it?)

    I believe that the original poster noted that he had spark. A failed
    ignitor would yield a no spark conditon, correct?
    I'll second the main relay. The symptoms described by the original poster
    are classic for a failed main relay, i.e., park it, let it set 5-15 minutes,
    then no start.
    Just knowing that the cam turns will not tell you if the belt slipped a
    tooth or two. You may want to verify the mechanical timing.

    If I remember correctly, Code 16 often indicates a failed main relay.

    Where did you put gas? There is no carburetor on a '91 Civic.

    This point also came up a year or so ago. I thought there wasn't a
    clear consensus on it. Or we said it might depend on the specific
    failure within the ignitor. Can't remember. I could be wrong, re the
    spark.
    minutes,

    I thought he implied the car is dead right now; it ain't starting no
    way no how.

    That's why I leaned towards the ignitor.
    He hears the fuel pump running, no?

    Anyway, as always this should be interesting.

    Just because the pumps running doesn't mean there is enough fuel pressure.
    Need to put a noid light on the injector or a test light

    Someone posted this link about Honda ignitors (among other things)
    today:

    http://techauto.tripod.com/s.htm

    It backs up Eric: Failed ignitor = no spark.

    Thanks guys for your help. Sorry for the confusion. I wrote I put gas into
    the carburetor meaning the throttle body /air intake plenum, after opening
    both butterflies. I would say it’s probably the original distributor
    ignitor. I have good spark, as well as I think plenty of fuel. After
    hearing the fuel pump in the tank running I wonted to double check so I
    removed the fuel pressure service fitting and turn the key. Gas shot out.
    After locating the main relay, I turned the key and could hear the relay
    opening and closing. The car has been sitting in my garage for about one
    week. I still have what I started with. The motor turns over but just wont
    start and run.

    As I mentioned before the main fuel relay is working. I put more gas down
    the intake and held the gas pedal to the floor. After about 1 minute of
    the engine turning over, the motor finally started and ran for about 5
    minutes. While it was running I sprayed intake cleaner into it and worked
    the gas. I thought that everything was good now that it's running. Then it
    shut off and didn’t start back up. Before doing any of this I cleared the
    code in the computer. After it ran and shopped I checked the codes and got
    nothing……

  9. Not to stir up the evil spirits or anything, but if the problem isn't
    ignition and fuel in the intake didn't make it just go "vroom - putt putt" I
    am worried about the timing belt. If you pull the crank through all four
    cylinders (CCW, remember) do they all feel like solid compression and they
    spring past TDC, or does one or more feel soft? Of course, the real test of
    belt timing is to turn the crank to #1 TDC and look at the position of the
    cam sprocket(s).

    It sure sounds like a jumped belt to me.

    Try checking for vacuum leaks. Also check the engine's mechanical timing.

    FYI. After one of the last messages saying if you put fuel into the intake
    and the motor didn’t start then you have a timing issue. I started to pull
    timing cover and checking alignment. Then checked over the distributor and
    rotor and noticed that somehow the rotor spun over the locking bolt. It
    seems that somehow the rotor got jammed and stopped rotating. After
    removing the entire distributor housing ( 3 bolts) I notice that the shaft
    that holds the rotor could wobble about ¼” and the bushings were shot. My
    buddy spent about $200. on a refurbished unit. After installing the new
    distributor the car started right up. Only thing needed now is borrow a
    timing gun to check my installation. Thanks to all that replied. Thanks
    for the help and ideals on what to check.
