99 GC 4.0 won't start, and beeps
I have a 99 Grand Cherokee Laredo 4 liter I-6. I just had the cv axles and shocks replaced, and everything was working great, except a rear taillight with a short. I parked it last night, and everything seemed normal. when I tried to start it this morning, it sounded like it was cranking slow, and would not turn over and the lights would dim. Then, there was just a clicking from the engine bay when I turned the key. I tried jumping the battery, and got it to start by pumping the gas peddle, but it would not idle at all, and just died. all of the lights work as do the windows and door locks, so I am pretty sure my battery is good (can't seem to find my multimeter right now). when I decided to give up for the day, I realized that when I turned the car off and removed the key and opened the door, the car started beeping like it does when the key is in the ignition and the driver's door is opened or the lights are on when the car is off. The beeping only stops when the door is closed or if the ignition is in the on position. The lights are all turned off, and the key is out, why would it beep at me, and are all of these problems related?
Please help, I just dropped my whole tax refund at my mechanic, and if I have to take it back in, I would love to know what I might be getting myself into before hand. Any insight is greatly appreciated.
