Hello...welcome and thank you for using Justanswer.
First thing I need you to do is comparing this picture to your matching marks , make sure this is the way you timed the engine.
Let me know.
Here's the mark on the crankshaft sprocket.
Also make sure the crankshaft sensor that you see on this same picture and the cam sensor in the back the driver side cam sprocket are plugged in.
Well, remove the spark plugs and dry them out, put them back in , disconnect the mass air flow sensor and try to start the engine ....no gas please.
let me know.
crank the engine for a few seconds with spark plugs out.
When you have the spark plugs out crank the engine to get the unburned gas out of the cylinders ,then clean the spark plugs and put them back in.
If you have a bad MAF it will flood your engine with gas and it will not start, this is why I want you to disconnect the sensor and try to start it at idle , don't rev the engine.
Let me know tomorrow ,during the day I will be working but I will check in when I have a chance.
OK, have a good night.
Sorry for the wait ,really busy here.
Are you sure on the marks ,you are not using the arrows on the cams as the marks ,right ?
Did you say there is compression on all cylinders ,did you use the a compression gage ?
let me know.
Yes ,it is possible that you have bent valves.
Were you driving when the belt broke ?
Did you over heat the engine before the timing belt broke ?
I would recommend removing the valve covers and loose the cams and then, do a leak down test.
You can force air into the cylinders using the compression test hose and then listen for air leak at the exhaust/tail pipe or trough the throttle body.
