Have a 924 that is turning over but not starting.Put new battery wires,new spark plug wires,new gaskets. But it will not run.It ran before we put it up on blocks but now we can't get it to stop pressurizes and trying to blow the boot off.Anyone have any ideas.

Check the plug wires and make sure they are in the correct firing order.

Is the cam timing correct? When was the engine last running, and what do you know has been done since?

#1 thing to do is verify that the timing belt marks line up if yes then move onto ign timing get out a timing let and set it to 6 deg btdc this will get it running if the fuel is working, if it still doesnt start then you are looking at a fuel issue, although has a compression check been run on the engine?
I would also recommend if it still doesnt start after checking the belt and timing to pull the cold start valve/injector and put it in a glass jar and test it, see if it turns on and sprays fuel, if the car hasnt been running in awhile you may also consider pulling the injectors and there is a rubber o-ring around them which sits in a grommet, replace the o-ring and pull the grommet out and seal it wil a silicone gasket maker,
