1996 Chevy Cavalier car wont start has no compression

Are you sure the timing belt was installed correctly? is there 0 psi compression in all cylenders?

well my brother in law did the work on it he hasnt put all the pulley and belts back on it yet or even the air filter and hoses he says only one cylinder has no compression i tried to tell him to put everything back on he also has the valve cover off it too.

Has he put the timing belt back on?

N he did not put the timing belt back on he has not put any of the belts or the pulleys they go one either and the alternator is not on either

Did he check compression with the belt off? If so, that is why you have a dead cylender. One of the valves is most likely open.

Let me know.

yes he checked the compression with the timing belt off and thank you.

That will do it. Let me know if everything is back to normal when you get it back together.

Joe

Everything is back on it and it is all together but it wont start it makes a plain like whinning sound not the usual sound it should make before it would start and it still has no compression. so we dont know what is wrong.

Recheck timing. It sounds like it wasn't timed correctly. If it was (and I don't think it was based on your description) then I need a compression test done and need to know the numbers you get.

NOTE: If it sounds like there is no compression (one steady sound when the starter engages) my guess is that the timing is still wrong. As before, you only said one dead cylender. Now it sounds like the all are dead.

ok thank you. we will get it check again by someone else this time

Let me know what you find. Remember, you had low or no compression in one cylender before. Now the belt is on, it sounds like you have none in any of the cylenders. That is why I feel it is on wrong.

we cant get the timing set right can you tell use how to set the timing on a 2.2L motor?

Here is what I found. Let me know if it helps or if you have something different. It's for a 2.2L cavalier.

okay we have the timing set like the diagram and now it backfires and wont start

Are you sure the plug wires are on the correct cylenders? Are you sure you are not off one tooth on the timing?

the timing looks set right on the marks and the spark plug cables are on the correct cylinders we dont know what is wrong now.

If it is backfiring, either the timing is still off even one tooth, the plug wires are wrong, or you have a burnt valve. If you check compression now, are they all good? Don't laugh, but is there any way you could upload a video of what it is doing so I can hear it? I realize that is a lot to ask, but it would help me help you.

Let me know.

Joe

PS: Please recheck the spark plug wires and let me know if it is backfiring from the intake or exhaust.
