    Re: why does my catera sometimes doesnt want to start

    My 2000 would run and then intermittently not restart, let it cool down and it would restart.

    The Battery was less than 10 months old. The positive terminal was getting hot enough to melt the nylon bag around the battery.

    Although the primary connection to the battery was tight there are two other bolts that connect wires to the terminal that were loose. Tightening that connection eliminated the excessive heat (resistance) and haven't had a starting issue since.

    Actually, your acronyms are slightly incorrect.

    CPS is the correct acronym for Crankshaft Position Sensor
    CPS can also mean Central Power Supply
    and CKPS is also known as a Crankshaft Position Sensor

    No, CKP is the correct acronym for Crankshaft Position Sensor.

    Manufacturers do not use the same acronyms for multiple systems/components. They each have their own.

    If CPS was the acronym for Crankshaft Position Sensor, and Central Power Supply, wouldn't it also be the acronym for Camshaft Position Sensor? (Nope. Camshaft Position Sensor - CMP sensor)

    From a Helm Cadillac Service Manual (1999 Seville):

    I don't see how CPS could be confused for Central Power Supply when the Catera doesn't have a Central Power Supply. I'm just saying.

    I never said anything about confusing it for something else, I was just pointing out the correct acronym (see my first post in this thread... Informative nitpicking).

    ...The Catera doesn't have a PCM, but you wouldn't use the acronym for something else.

    There have been a good number of members here, since I joined the forum, looking for diagrams of the CKPs, and wondering why they can't find any on Google. It's because the dealer websites and parts websites that have diagrams list the correct acronym, and they're searching CPS. There is an advantage to correct terminology.
