We will have to pinpoint what the engine is missing.


Spark


Fuel


Compression

 

All three of these are tested when the engine is being cranked over. There are two way of checking for fuel. Fuel pressure and fuel trigger. Both are very important and must be present for the car to start. Fuel pressure is self explanatory. You just hook up the gage and see what the reading is. Fuel trigger is check with a noid light. The injector gets unplugged and the noid light gets plugged in to the injector clip. With the engine cranking over, this light must blink. This is the signal to the injectors from the computer. You can have all the fuel pressure in the world, but it wont matter if the injector is not pulsing gas into the cylinder like it should! Compression tester, spark tester, fuel pressure gage and noid light are all accessible at your local auto store. All three tests play a very important part in diagnosing a no start condition.

The engine does nothing. No crank, no grind, no noise at all. Am I understanding you correctly that the broken PCV elbow would not be the cause of why the engine does not turn over? If this is the case my second guess is the clutch switch for the manual clutch then

Different tech here, The PCV will not cause starting issues, however it will cause running issues so it does need to be addressed to prevent lean running concerns and oil atomazation from getting all over the engine compartment. Since your vehicle does nothing when you turn the key then we need to diagnose the starting circuit to see if all the fuses and relay have power and are sending there signals out and there are no starter inhibit switches like the clutch switch causing this concern. Follow the below wire diagram I have addressed areas of concern in .
