420A Timing Belt Stuck

[Skyline-Tweak]

I was driving down the highway with my brother the other day when my car shut itself down on me. I pulled off the highway to the shoulder only to see that the timing belt tensioner bolt backed itself out and ground itself down and caused my belt to get stuck behind a pulley. We redid the timing and now the car won't start. It does turn over though. I know the timing is correct and it's definitely getting spark. I smell gasoline after trying to start it though. Could the valves be bent? How would I check without pulling off the head? Any help is appreciated.

Pull the plugs, turn over by hand, if no metal sound, do a compression check.
That bolt shouldn't back out, it was never tight

Does the engine rotate freely by hand, as in using the crank bolt and a socket/wrench to rotate? It very rare that a belt will break or get stuck in your case and not bend valves!

I'm sure the timing is off, now that I think about it. If you had bent valves, you'd hear it, and it would still start unless it was bent sideways.

We pulled the plugs and head each one to the valve cover and seen spark for each one. We redid the timing twice. It ran the first time we redid it but it wouldn't idle anything under 2000 rpms. Other wise it would shut itself off and drop to zero, so we redid it a 2nd time. It does rotate freely by hand. I rotated it with a wrench when we redid it the second time on the crank bolt to make sure the timing lined up.[DOUBLEPOST=1411149233][/DOUBLEPOST]It also shook very violently went we redid it the first time. Both the engine and the car.
