Question about Cars & Trucks
WELL WHEN TRING TO START TO IT JUST TURN OVER AND DONT TRY TO START ITS SOUND LIKE A WHINNING SOUND WELL I PULLED NUMBER 1 SPARK PLUG AND WENT TO TURN IT OVER AND WAS IT WAS GETTING NO SPARK SO THEN I PUT MY FINGURE OVER NUMBER 1 SPARK PLUG AND TURN IT OVER WELL U WOULD THINK THE COMPRESSION WOULD BLOW MY FIGURE OFF THE HOLE BUT DIDNT RIGHT BEFORE THE NEON DIED I JUST REPLACED THE SPARK PLUGS AND THEY LOOK ,IKE THE OLD WAS BURT LOOK TO THEM
I suggest you check the timing belt/valve timing and replace if necessary ad then perform a compression test. A broken belt could mean bent valves.

SOURCE: dead cylinders 2003 sebring
it sounds like you may have the wires on the wrong coil. It should be #1 on the #4 coil, and the #3 wire on the #2 coil. you probably have them backwards so 1 and 3 are firing on the exhaust stroke.
the firing order is 1-3-4-2.
they should be hooked like this.

SOURCE: turns over but wont start
Yes.. connect a fuel pump pressure gauge to the fuel rail - turn the ign key to 'start' and watch the fuel pressure gauge.. if NO pressure.. you found the problem... .could be wiring or the pump itself.

SOURCE: no compression in engine
Hard to believe broken rings on a car only 8 years old?
If rings break, there would be lots of crankcase pressure, blowby, and oil leaks everywhere. I have even seen dipsticks shoot out.
Rings are broken by not letting an engine warm up, before very hard acceleration. And you will never break rings evenly in more than one cylinder at a time. So seems very unlikely.
Finally, if compression really gone, then engine would crank over like a demon. With no resistance, it would spin like crazy.
I think the real problem is the timing belt jumped.
The belt did not totally break, but a backfire or something caused it so jump one or more teeth. This will cause the camshaft to hold the valves open and you have no compression then.
Check the camshaft timing.
Basically what you do is turn the crankshaft to TDC (Top Dead Center) of the timing marks, (usually on the crankshaft pully, but sometime on the flywheel, through a viewport).
Then with the cover off the camshaft shaft should have a visible mark that is supposed to line up with a marker, the plane of the tops of the head, or something. Not hard to do, and you can look up the actual marks in the library.

Need to check for fuel. Easy way to do this is wipe one of the plugs clean and dry and put back in without wire attched. Crank truck as if you were trying to start it. Pull plug out and check to see if it is wet. Should smell like gasoline. If so, recommend you replace the plugs, wires, distributor cap and rotor. If not, you have a fuel problem.
