    Hi everyone after fixing the fuel pump relay and the water pump gasket. the
    volvo started right up and we drove across town and back all is well... go
    to get in it later go to Shucks to take back a few things it will not
    start. so this morning i go to start it and it starts right up. later on
    in the day it will not start again. take the battery out to take it to
    shucks which is close and will test your battery. battery is good very
    good. kid says how about your alternator? god question could that be the
    problem? this starting when it wants is really pissing me off and my wife
    is going to start in very soon....thanks for your help.

    So it's not even turning over? Intermittant start problems where it
    doesn't turn over are usually the starter, they can also be the ignition
    switch.

  4. Check the quality of the Ground (Earth) strap connections on the chassis
    runner, engine block and battery. Also check the battery feed to the starter
    motor and the starter solenoid again for contact problems.

    All the best, Peter.

    If the engine is turning over normally then the battery is fine. The
    power required by the rest of the stuff is trivial in comparison. If the
    battery is too low to start the car the engine will turn over very slowly.

    i checked the battery and it is good checked the alternator, its good car
    sounds like it wants to start but cannoti recently changed the fuel pump
    relay amd the water pump gaskets so maybe i messed something else up in
    the process.

    Bad frequency valve, perhaps?

    940 won't have one of those, it'll be LH-Jettronic or Regina.

    Depends on the system, LH-Jet will have a prepump in the tank followed
    by another pump mounted under the car in front of the left-rear wheel
    well. Newer will have a single main pump in the tank.

  12. hey guys, the one i am talking about us mounted
    "out side" the cabin, under the car, right about under
    the drivers seat.....my mechanic showed me this trick one
    day mine took a "brain fart". he said sometimes the pumps
    stop (these are for well worn pumps) right between
    the wires or electrical components, so that a tap will move
    them enough to run again.....anyway..i used this method
    to get started about 5 times over the next 20k miles in
    my 1993 940t untill i could afford a new pump installed..
    for about $400...or so...

    anyway, get a medum wrench or hammer and crawl under
    the car so you are about under the drivers seat, look up
    and you will see a round fuel pump...gentally tap it a few
    times and start car...if it works, the pump will need replacing
    sometime soon, in the meantime, just tap when it acts up...
    good luck !!...

    btw: i think there is another pump in the fuel tank...

    It happens if the commutator is very well worn in some segments and the
    brushes are not making enough contact for the pump to start running if
    it happens to stop on one of these more worn segments so yeah sometimes
    you can buy a little time by banging on it, I certainly wouldn't count
    on that lasting long though, it's just asking to be stranded.

    You can buy a pump online for less, it's pretty easy to install with
    basic hand tools.

    Thanks that could be the problem the ectrical system seems fine and it
    started and then just stoped and then started again. this car is new to me
    and i am not a real experienced mechanic but this could be the answer. i
    love this car and i hate driving that crappy van my wife has. thanks.

  15. go through and think about the basics:

    fuel
    spark
    compression

    "Thanks that could be the problem"

    what did you do or try??
