One day just wouldn't turn on. I had left my lights on tried to jump it No go. Got the battery tested and found out it had a hole! so replaced the battery and still its a no go.

does the light come on when the key is turned to the RUN position ???
no, not good
light is powered from the key, to the bulb then it grounds through the alternator when the alternator excites... that's what the light it, it's the exciting circuit, or it's how the alternator turns on. light not working, alternator not turning on...
have you tested and made sure you have power on the main alternator wire from the battery ???
do you own a test light and/or DVOM ???
flassed less engine power wth?????????
Flashed reduced engine power ! Electronic throttle control problem ! Your best bet ,take it to a GM dealer , buick , cadillac , GMC . You do not have diagnostic test equipment or knowledge to even diagnose this.
The usual cause of this is a dying battery, which has enough charge to pull in the starter solenoid (the click), but not always enough to crank the engine.This is because such a battery cannot hold a good charge for very long.
If you feel your battery is definitely OK then it would be the large contacts at the bottom of the starter solenoid, which are worn out. The solenoid pulls in but contact is made only intermittently. I had a Toyota once which did that.
First try jumping the vehicle. If it won't jump you you need to check the main buss fuse in the power distribution box (Should be a 40 amp). If that is good check for a grounded positive going to the starter where metal contact with the wire may have worn a hole in the insulation. If both are good and the inline fuse from the positive is not blown pull the alternator and have it and the Voltage regulator checked at Auto Zone, Advance auto or Pep Boys. One if these is going to be the problem.
sounds to me that you have an igniton problem not a starter problem and or if you have or had an alarm system could be cause if u do give me feedback and i will explain but seems that your starter is fine from what u say but if you think in terms of the elemts to start a vehicle batery gives pwoer to ignition which sends to starter which gives spark etc i would check you ignition system something is causeing a short and not alowing starter to function
Check the voltage of battery with voltmeter.. It is sometimes possible that if voltage of battery drops and jump start is needed, your computer will only charge to the last voltage that was recognized which would be when jumped...Try and charge the battery if possible I would actually suggest that you have your battery tested at local auto parts store and if it is presumed in good condition ,let them charge for you to max capacity . If battery has been tested and labeled as no good replace if necessary... Oh, and first thing you should do is make sure your positive and negative battery connections are clean and tight...if this didnt fix problem please give more info on what was found when advice above was followed...Good Luck!!!!
