my baby won't start any ideas, thanks
Hi there, my 1996 sebring jx 2.5L die on me, i found out that the timing belt skip on the crankshaft like 4 teeth or it a full ratation plus 4 teeth, i install a new one and move all the timing marks on both camshafts and crankshafts to lign up the ones on the body. i also made sure that #1 was at TDC and that rotor on the distributor was om #1. i check all my relays and fuses, my fuel pump works and i check my spark plug cables and there was spark, and of course my spark plugs too. battery is good too, i crank the engine and it turns over but no start instead it turns then like a small combustion like 4 of them and little smoke come out from the intake manifold. any ideas why it doesnt want to start? i know that the crankshaft rotates twice than the camshaft, does it has anything to do that i could be one crackshaft rotation off?
thanks i would really appriciate if anybody knows my problem.

On that engine, the ignition is controlled by a distributor that runs off the camshaft, so it shouldn't matter that the crankshaft is "one rotation off". The crankshaft just sends the pistons up and down.
It's conceivable that some internal damage occurred when the timing belt was off by 4 teeth. That could be ruled out by checking the compression. There are several threads in the forum here started by people having similar problems. Browse around and pick up some more ideas.

If you have zero compression on all cylinders, there's a pretty good chance that all the valves are bent due to the timing belt being 4 teeth out of place. Time to pull a head off and see what's going on.
Yes, TDC on the compression stroke is different from TDC on the exhaust stroke, but whether it's compression or exhaust is determined by the camshaft. If the valves are closed, it's the compression stroke. If the exhaust valve is open, it's the exhaust stroke. The camshaft is what drives the distributor, and the distributor tells the spark plug when to fire. Like I said above, the crankshaft simply runs the pistons up and down. The crankshaft has no way of knowing whether it's on the exhaust stroke or the compression stroke.
