    2000 Cadillac Catera wont start...lost...help?

    2000 Cadillac Catera wont start and I'm completely clueless...

    According to our client, he was driving home and the car reved up a bit and then died... Towed it home and
    he has been trying to figure it out himself since May...

    Here's the deal..

    It is throwing a P0340 which is a CMP or camshaft position sensor circuit.

    We have done every test we can think of and our client has replaced the parts at the bottom of this thread.
    The signal going to the the CMP is good, good signal, good ground (no resistance, Power is a good 12+volts.
    We have replaced the CMP and still NADA!

    Obviously there is alot more to test although the part that is stumping me is that according to All-data the
    car should still start, and run in a sort of non-sequential fuel injector operation regardless of the CMP. So
    is it a bad ECM? I'm running out of ideas... PLEASE!!! Someone tell me what im missing!!!
    THANKS!!

    REPLACED
    -Cam Position Sensor
    -Crank Position Sensor
    -Fuel Pump

    Give up. From experience Caddy dealers don't want anything to dod with the car.

    Do you ever get sick of hearing yourself say the same thing over and over and over again. Maybe YOU should give up coming to this forum and wasting your time because not one person wants to hear it. Your posts are useless. Anybody who owns a Catera knows the risks. Point blank.

    And by the way he didn't ask anything about a Caddy dealer.

    A faulty ECM is a possibility. The diagnostic tree for that code should have steps to diagnose the ECM as the problem.

    I have a 2000 Catera that runs perfect, when it will start.. 177,000 miles and 2nd owner...from what ive been reading I may have made a bad buy..
    1,400.00 with new pirelli tires around it..
    The wife had to have this one?? Now it wont start after 3-days... ran perfect for a month then this....never stalled out, just shut it off and it now sits in the driveway..........

    ----------

    The 49- was simple and easy to work on..
