my 1994 gt mustang 5.0 ltr. will turn over but not start. please help me?

Check the fuel inertia switch first. Do you hear the fuel pump prime when you turn the key to on? If not, I would check for fuel pressure. Also check for spark.

Then if you have spark and fuel but it still won't run do a compression test. If all cylinders test very low or zero it's jumped timing! Hope that helps! Jim

try looking at the fuel pump and the spark plugs try changing the batterie
