Well engine size would be helpful... saying "turn over" I'm pretty sure you mean it cranks but doesn't fire. when was the last time it did run? what was done since then?
We will asume it has compression, so check to see if you have fuel (pull a plug and smell for gas) do you hear the fuel pump working?, you can also check the fuel pressure if you got the equipment. But if not move on and check for spark. So take that plug you just pulled and ground it, while turning the motor over look for a spark. If you got spark, check your Gap to what it should be (not knowing the engine size at this point I can't help you) If that one is off, regap all your plugs. If you have spark then check your firing order. 5.0 is 1-5-4-2-6-3-7-8 the 5.8 is 1-3-7-2-6-5-4-8 I don't know the firing order of the straight 6 off the top of my head. right bank (passenger side) from the front of the motor to the rear is 1-4, so the left bank from the front to the rear is 5-8 and the distributor is counter clockwise rotation.
Just keep it simple, you need to find what is causing the non fire start. that should get you going in the right direction. you need compression, spark, fuel, air in the correct timing. also check your codes and or trace fuses if you think fuel or spark is your problem.

yo CAM,
This is one of the best, take time to read and get some cheap stuff @ Radio Shack; Radio Shack #276-0270 Red LED Assembly $2.49 and extra wire and 2 alligator clips; 12 Volt Automotive Test Light
Youll need a multi-meter, Repair Manual (or just ask Qs here on what you may be stuck on) & a Helper
No Start and or Misfire, etc.; Thick Film Ignition (TFI) Testing, Overview & Diagrams, Distributor Mounted Ignition Control Module (ICM);
"...Part I; In This Fast Test you'll be able to pinpoint the problem to the Ignition Control Module or the Ignition Coil or the Profile Ignition Pickup Sensor (PIP Sensor) in four easy test steps.
This test will only help you in a Cranks but Does Not Start Condition.
So then, before starting the tests, it's critical that you have checked and verified that there's NO SPARK present at the Ignition Coil. Why? Well, because if the Ignition Coil is sparking, it would be a clear indication that it and the Ignition Coil and the Crankshaft Position Sensor (PIP Sensor) are working.
Ignition Coil Test -No Spark No Start Tests @ http://troubleshootmyvehicle.com/ford/4.9L-5.0L-5.8L/how-to-test-the-ignition-coil-1
Instead of buying a HEI Spark Tester, Make a Spark Tester
This article applies to both the Gray colored Ignition Control Module and the Black colored Ignition Control Module. The Gray colored Ignition Control Module is called the Push Start Module and the Black colored Ignition Control Module is called the Computer Controlled Dwell Module. These ignition control modules are not interchangeable.
