Put a brand new alternator in and the car still does not start. I'm wondering what the real problem is that is not allowing my car to start. Please if you have any answers for me. I would appreciate any suggestions that may fix the problem I'm having. Thank You

    There are many causes that may cause car don't start:
    Low battery;
    Loose or corroded battery cables;
    Bad starter relay wiring connections or ground connection;
    Bad starter relay/solenoid;
    Bad starter;
    Damaged starter drive or teeth on flywheel;
    Bad ignition switch;
    Engine seized due to bearing failure or internal damage;
    Engine hydrolocked due to coolant leak from leaky head gasket

    I suppose to eliminate and check those causes one by one.

    Good luck.

    Your car does not need an alternator to start.
    Whoever told you to put an alternator in to fix it should not be trusted.

    my car had the starter changed and Pep Boys put a hole in my transmission which caused fluids to leak where they weren't supposed.

    My '97 Seville had that problem after I replaced the alternator. Everything was working fine beforehand except the panel said, "battery not charging" The replacement is not for everyone but I managed. The car tried to start, then all lights when out -- the car was dead, nothing worked. I removed and checked the alternator assuming it had a short, charged the battery; both checked GOOD. After checking fuses, solenoids, alternator wiring and anything else I could think of, I hooked my meter to the battery, had my wife attempt to start the car, and the battery went to 8 volts and then to 11.5 V. I took the 1-year-old battery back and after checking it, they warrantied a new battery. One for the books, very dependable now.
