88 z28 wont start or turn over
so coming back to my 1988 camaro to try and fix it and garage it before it snows or gets too cold and it wont start or turn over, i charged the battery and tried to jump it but it wont even try to turn over. its been sitting for a couple of months without being ran and the transmission did recently have water in it any ideas where to start? could it be a starter?

Car Is Not Cranky, So Owner Is
Use a spare headlight (because it puts a load on the circuit) and connect it across the M terminal of the starter and ground.
Then connect a voltmeter across the M terminal and ground.
Make the leads long enuff to take the lamp and voltmeter into the cockpit.
Under normal circumstances you will see about 9 volts on the meter.
On the occasions the starter fails to crank note the voltage.
The voltage will tell you what the problem is and what direction to turn.
If it’s about 12 while trying to crank, but the starter is not turning - the problem is in the starter.
If it’s under 8 while trying to crank - the problem is excessive resistance in the starting circuit.
Therefore if it is in the starting circuit you can move the probe you applied to terminal M at the starter, to the positive terminals at the solenoid, then keep moving up the line till the problem shows itself.
