    My 1999 SC2 died on the way home from work a couple weeks ago, and I just
    got around to replacing the fuel pump today (like everyone told me it was).
    Well, it wasn't the pump. I still don't hear the pump run when I first turn
    the key to 'on'. I switched the contactor with the one for the HVAC
    (they're both the same model number) and still no juice. Does anyone have
    an idea for me? My wife needs her car back, so I need to get this fixed.
    Thanks in advance,
    Justin

    Did you get the fuel filter as well?

    Start over, what is it doing, give us symptoms. Does it give out hot or
    cold? Does it start to stumble before it dies? Will it not start hot?

    You need these 3 things for that engine to run, Air-Fuel-Spark. What of
    those 3 is it not getting?

    There is a fuel pump priming wire near the battery. For future reference
    try it, you dont need to swap relays to prime the pump.

    Ok, here it is from the beginning:
    My car has 136000 miles on it and it has been perfect running from the day I
    got it with just 32 miles on it. I'm on my way home one day and all of a
    sudden the car dies for no apparent reason. I pull off the road and check
    for obvious things and see nothing. I then try to start the car and it does
    just fine and I complete my little journey home with no other problems.
    The next morning on the way to work the car dies again (coincidentally at
    almost the exact same place as the day before) but this time it will NOT
    start back up and has not since.
    I checked the car for spark, and there is definitely spark. The air filter
    is fine, practically brand new. I have not replaced the fuel filter,, but
    it wasn't my first point of attack since the fuel pump wasn't running. I
    checked the fuel lines for pressure and there was none. Everyone I spoke
    with said "that's easy, it's your fuel pump". Sooo....... I get a fuel
    pump and replaced it the other day. I was all excited when I put gas back
    in the tank and turned the engine over, and over, and over.... you get
    the idea.
    Where do I go from here? Any and all ideas are much appreciated.

    So are you or are you not currently getting fuel pressure? If not there
    "should" be (not sure with saturn) a red wire not hooked to anything
    near the battery. You can jumper that to the positive post and that
    should supply power straight to your fuel pump. You can even try
    spraying some starting fluid into the intake to see if you get the motor
    to hit that way. Just dont spray to much.

    I am not getting fuel pressure. I don't see a red wire that I could hook up
    to the battery, so Saturn must not have done that. I checked the fuse, and
    the contactor, and still no luck. Anything else? I plan on working on this
    in the morniing. Thanks!

    Well I wish my copy of GM eSI covered Saturns... You could really use a
    schematic for this. You're probably not getting power to your fuel pump.
    You will need to start tracing down why that is. You can always go back
    to the pigtail coming from your fuel tank and hook a 12v source directly
    up to the fuel pump to see if it runs. (incase of fire be ready to get
    the heck out from under there.)

    Good luck.

    I got it figured out. I opened the trunk this morning to hand-over-hand the
    wires and I saw a 'lake' in the drivers side of the trunk. The seal on the
    trunk is leaking allowing water to accumulate in the recessed area behind
    the wheel well. I drained the water out and saw a badly corroded connector
    that just happened to go to my fuel pump. I cut tthe wires and put in butt
    splices in its place and the pump runs fine. Thanks for your help!

    is there more then 1 fuel filter maybe? I have heard of more then 3 on
    some cars. One at tank, inline, and one by the motor in some cars.
    Just so you know.

    There is a pickup screen at the pump, seldom ever gets clogged. Then the
    fuel filter, then some small screens pressed into the injectors. Thats
    all that I know of.
