ya its low on compression in some cylinders but no total loss of compression. You think low compression could keep it from starting though?

Is the fuel pressure good? Will it start with a shot of starting fluid?

A severe lack of compression might suggest, among other things, a broken timing chain.

That will eliminate it to the fuel system, you really need to determine what the check engine code is
