Ford Mustang: 98 Cobra won't start

    98 Cobra won't start

    Hello all,
    My roomate's 98 cobra has been collecting dust on our driveway for the last
    year.

    He drives it like he stole it, so it's understandable that after time,
    something will break. He started to notice upper-RPM power loss, so he took
    it to the dealer. Apparently he used a batch of bad gas that pretty much
    toasted all of his engine's components, and they replaced the engine under
    warrantee.

    And again.

    And again.

    The dealer checked the fuel filter, fuel pump, injectors, etc., and after
    dumping tons of money into "let's try this, let's try that" to attempt to
    fix it, it's still not running right.

    As a matter of fact, it won't even start now.

    The last thing the dealer tried to charge us for was new plug wires. We
    laughed in their faces and took the car home.

    We finally gave in to curiosity and put on a set of OEM wires, and no go.
    (duh)

    We're at our wit's ends here and we can't really think of anything (other
    than ANOTHER bad engine) that will prevent it from starting and running
    correctly.

    The engine cranks but doesn't turn over. We recently but a set of Accel coil
    packs and it still didn't help...

    What do you think? Lemon? If so, anyone have any luck challenging FoMoCo and
    getting them to buy the car back?

    My 98 GT had a non-starting problem. Turned out to be an oxygen sensor broke
    off & ground against the body of the car pulling 109 amps.

    engine were "toasted" it would do worse things than just loose some
    upper-rpm power. 
    coil 
    the start motor tries to turn over the engine and cant? 
    and 
    shouldnt be anything "lemon" left inside. 
    or by yourself, doublecheck the ignition order, take a look at the plugs,
    check the distributor, check the fuel pressure, check that the fuel pump is
    running, check the air filter.

    *sigh* so many probabilities. Get a local precision tune (if you have one)
    to hook up a circuit breaker to it & debug. Can get costly though.

    THAT is an excellent Point!

    The PATS system will NOT work in some ECMs!

    jriegle,

    I have no idea, but that's what they said. It blew a 30A fuse (it's supposed
    to have 20A fuse) immediately too. Once that O2 sensor was replaced it
    worked perfectly. Started right up.

    | The O2 sensor only carries a small sensor voltage from the computer. How
    can
    | it pull 109 amps??

    Dead short in the sensor - it'll pull whatever the battery will supply and
    the wiring will tolerate - until the fuse blows..
