    Angry My 2001 DTS didn't start every time..... Please Help

    HI EVERYONE , How are you

    This is my problem:

    starting failure like whats happened to a lot of cadillac owners.
    the problem detail: everything working fine from the key to fuel pump to the dash panel and no DTC error but after all of this the car doesn't start.
    and the stupid solution we had to do it everyday is trying to start the engine so many times until starts.
    please help me.
    Regards, RoOoGy

    Start by checking your fuel pressure.

    What is your fuel pressure?

    Might try cleaning the TB. Does it start easier if you crack the throttle open?

    I did cleaning the TB and I tried to keep the throttle open when I start the engine and nothing happened.
    thanks for your help ( Ranger ).
    and the problem still happening.

    Once again, what is your fuel pressure? Gotta start with the basics. Otherwise we're just guessing.

    Rent a fuel pressure gauge, hook it up to the Schrader valve on the fuel rail, turn the key to the ON position.

    If you had the pressure checked and he used a fuel pressure gauge, I guess it should be fine then. The "stupid solution" you mentioned in post #1 led me to think low fuel pressure.

    How does it run after you get it started?

    Post Re: My 2001 DTS didn't start every time..... Please Help

    Hi, Additional info: when I noticed the problem I thought its PASSKEY III issue but when I read about it and seeing this webpage http://www.pdqforensics.com/sec410010.html but i was wrong because the PASSKEY III its security starts with the key and ends with the fuel pump, and all of that working in my car.
    and I know someone who told me the problem maybe in the starter or the starter connection ( wires ).
    so I'm very confused so help me please.

    and my problem the same in this video:

    Wait, so the problem is the engine doesn't CRANK?

    I think we were all under the impression that it was cranking and not starting.

    Ok, that changes things. Fuel pressure and cracking the throttle open are irrelevant. The problem is with the starting circuit. Does the starter relay click when you turn the key?
