Does the vehicle start after sitting over night or do you need to jump start it . Is the charge light on ( batt. symbol ) at any time ? Serpentine belt good , tensioner good ? Battery cable connections good an tight and no corrosion ? Battery also good ? That is normal for battery voltage to jump up to 14 volts after starting , alternator is replenishing the battery after starting ,that draws down the battery . Going down to 11 or 12 volts when stopping and almost stalling isn't a charging system problem . You have a idle problem , IAC - idle air control valve or dirty air passage , a vacuum leak . Giving it gas and it going up to 13+ the alternator is working . Your best bet take it to a qualified repair shop and have it check .

It could be a blown head gasket, crack in head or engine block, a freeze plug or water pump gone bad. You need to have it pressure tested. A pressure tester connects to radiator and is like a bicycle air pump. It puts air pressure inside the cooling system and wherever the leak is..it will leak much faster and heavier under pressure making it easier to detect where the leak is coming from.
You can borrow a pressure tester from AutoZone. They have a loan a tool program..You leave a deposit they loan you the tool, when you return tool the deposit is returned..no fee charged involved..

Check your battery cable connections at the battery as well as the engine block. On the block remove and clean ground real good.

quoil ? Coil ! This is a very complex ignition system ,rather replacing parts an costing yourself a lot of money do yourself a favor an take it to a ASE certified repair shop ! Could be any number of things ,from one of the two crankshaft sensors , cam sensor , ignition control module , engine computer etc.. Are there any codes stored in the PCM ? That's the first thing that should be done , have a scan tool hooked up !
The ignition system uses a waste spark method of spark distribution. During cranking, the Ignition Control (IC) module monitors the crankshaft position sensor signals. The signals are used to determine the correct pair to spark first. After the crankshaft position signals have been processed by the IC module, it sends a fuel control reference pulse to the PCM. When the PCM receives this pulse it will command all eight injectors to open for a priming shot of fuel in all cylinders. After priming, the injectors are left OFF for the next eight fuel control reference pulses from the IC module (two crankshaft revolutions). This allows each cylinder a chance to use the fuel from the priming shot. During this waiting period, a cam pulse will have been received by the PCM. Now the PCM begins to operate the injectors sequentially based on true crankshaft position. However, if the cam signal is not present at start-up, DTC P0340 will set and the PCM will start fuel delivery in a random pattern with a 1 in 8 chance that fuel delivery is correct.
The crankshaft position sensor signals are used only by the IC module. It is used for spark synchronization and to initiate reference pulses only (not passed to the PCM).

  1. Install spark tester J 26792 on one spark plug wire and ground that cylinders companion cylinder plug wire.
  2. Crank engine while observing the spark tester.
  3. Repeat the above steps on at least one more cylinder.
Does the spark tester indicate a crisp blue spark on all tested cylinders?

Go to Step 4
Go to Electronic Ignition (EI) System Diagnosis (Ignition System Check)
When any condition is suspected to be caused by or related to the ignition control system, the first step in diagnosis should be to check for stored PCM DTCs. Diagnose all DTCs before further action is taken. If no DTCs are stored and the condition is still present, refer to the following:

ensure coil is correctly connected, battery is okay? If the coil gives no power and is correctly connected it will need to be replaced
It cannot be repaired

as both units are indicated I would be checking the wheels for broken sensor wires or faulty sensors
both units use the same wheel sensors.

You can't just disconnect the anti-theft system ! . If the modules on the vehicle don't receive a coded response form the anti-theft system the vehicle will not work , no start ! This coded response is send on the class 2 serial data communication bus to the PCM - engine computer , if it doesn't see it the fuel system , fuel injectors won't be turned on ! an in some cases the engine won't even crank over !
I have read of a way to by pass the system ! If you google GM vats an pass key by pass , you will see how to do it . Don't know if this works or not ! Haven't tried it !

The brake release is vacuum operated. Check to see if a hose broke or maybe just fell off.
