    I have a '96 SL1 that keeps stalling! It usually happens when the car
    hasnt been run for a few hours. It will run for 20sec then turn off
    like I turned off the key! I can hear the fuel pump prime, so I dont
    think its the pump. If I let it sit for a little while it will
    usually start back up and be good for the rest of the day. Yesterday
    it did not want to start back up. When it did, it eventually stalled
    again. Last night I ran it in the driveway for a couple hours with no
    problems after it stalled and I started it back up. Today I tried to
    start it and it just turns over. I have had people tell me many
    different things. Crank sensor, bad gas, weak pump, bad computer...
    Where should I start? The engine light does not come on. If the
    crank sendor was bad, wouldnt I get a code? HELP!!!!!

  2. Hi:
    A crank sensor will not set a code!

    Throwing parts at a car is a bad thing, because I do this for a living. The
    first thing to do is to get someone with a good scanner. That gives readouts
    in real time.

    To me, it sounds like you've got a loose or corroded connection from the
    crank sensor, to the ignition module, or a loose connection on the module.

    Also, it can be the fuel pump is loosing prime. You'll have to test fuel
    pressure and volume. I don't remember the pressure specs on a Saturn, but
    the volume should be 1 pint in 10 seconds or less.

    I hope this helps.

    Have you ever checked to see if you have spark when it's in the stall mode
    ? If no spark that should point toward ignition.

    Hello, I have a 2002 saturn L200 that is also stalling at highway
    speeds. I had it towed to the local saturn dealership.
    They have run diagnostic tests and say they can't get any error
    codes. I asked about ignition coil, crankshift and camshift
    sensors and they said that they can't test for that. Would I be better
    off taking it to an independent mechanic?

    If your Saturn dealership troubleshooting ability is limited to just
    examining error codes I think I'd look around for an experienced
    independent !
    ( Just my opinion. )

    Or another Saturn dealership.

    I picked my Saturn L200 up the other day from the saturn dealership.
    Here is what they told me. That the reason for the car stalling is
    probably something wrong electronically. Without an error code they
    would just be guessing as to what the problem is. They could replace
    parts but they would not know if it would fix the problem or not.
    Their best advice is to keep driving the car until whatever the
    problem is breaks and leaves a hard code. (check engine light) This
    doesn't sound like a good option to me because I don't know how safe
    it would be stalling at highway speeds or in the middle of an
    intersection. Anyway, after leaving the dealership I stopped at a
    local independent car shop just to get a second opinion. The guy there
    pretty much told me the same thing. Sometimes I wonder what did
    mechanics do about stall problems before the computer diagnostic era.
    At this point I'm just driving the car locally, back and forth to the
    grocery store, etc.

    Well, modern cars are tougher. For one thing because the under-hood is
    so crammed it's hard to get to stuff.

    Having said that: Temperature is often the culpret. I once diagnosed an
    intermittant Taurus ignition module by removing it, putting it in the oven
    to get hot (car wouldn't run) and then chilling it (car would then run).
    But, that module was easy to get to. Coils are another item that can fail
    when hot but work OK cool. You might try to get them to try heat on
    whatever they can get to. As an ex electronics tech and later engineer I

    I think they just threw parts at the vehicles; albeit vehicles that
    didn't quite so many parts.
