Greetings,
I own a 1996 Buick Regal Custom with a 3800 II engine a/t. My problem is that I cannot get it to start. Once I turn the key, it almost sounds like the starter is trying to go in and out of the flywheel. Kind of like a rapid fire. I have apprx 12.37 volts from the battery and have tried the spare key. All fuses are good. Does the same thing whether in Park or Nuetral. I even tried jumping the starter with no luck. When I jumped the battery from another vehicle, it just clicked once, not a rapid fire. Removed front 3 spark plugs to see if I could relieve any pressure but to no avail. It just doesn't seem to try and catch to turn over. Any suggestions?
