Question

Answer
You first need to see if you have spark,then check see if you have fuel pressure.Checking the intake hoses to make sure they are not hard or cracked,and the seals,gaskets are not leaking oil.You also need to check the compression.By removing the spark plugs this can be done.(inspect the plugs for any damage)Diagnosing from there,having some of this basic information will help me help you.
