    The car stalled on me, going up a hill, and it's won't start
    any suggestions:

    so far I've checked:
    60 psi on fuel pressure pump, starts when key turned on
    lot's of sparks, 12 V on the igniter
    165 psi compression on each cylinder
    no faults on the ECU or in the dash, power to the ECU (one blink)
    no fuel going to the engine between the line and the injector (s)

    any ideas..?
    O2 sensor?
    car has 85 000 km's (15db1 engine)

    My Haynes Repair manual lists these causes for: Engine Stalls
    1. Idle speed incorrect.
    2. Fuel filter clogged and/or water and impurities in fuel system.
    3. Distributor components damp or damaged. (Is the distributor cap cracked?)
    4. Faulty emissions system components.
    5. Faulty or incorrectly gapped spark plugs.
    6. Faulty spark plug wires.
    7. Vacuum leak in the intake manifold or vacuum hoses.
    8. Valve clearances incorrectly set.

    It stalled and won't restart, I have the same book
    I suspect #4 faulty emissions system components
    but not sure we're to start, is an o2 sensor can prevent a "no start
    condition", or an intake air temperature sensor

  4. As far as I know, a faulty O2 sensor never causes a no-start.

    In most cases, the engine light would come on if you have problems
    with the o2 sensor. One thing that is not on the list is the "fuel
    throttle bore". It should be mentioned in your repair manual. You should
    clean it. You should also replace the intake manifold gasket.
    Did you replace the fuel filter? It's possible that the problem
    is dirty gas or gas that has water in it. If that is the source
    of the problem--the problem will not go away until you burn that
    tank of gas. If you are not a mechanic, you should consider
    having the car towed to a mechanic. The mechanic could hook up
    the engine to a computerized engine tester and figure out the
    source of the problem.

    Is the car still on the hill?

    the 3 known probs for that vintage are:

    igniter
    main relay
    ignition switch.

    but from what youre saying, it all checks out.

    i'd check the main relay, despite the lack of codes. go to tegger.com
    and look for the diagnostics & repair.
