Car will turn over but will not start. It seems like I am not getting any spark. I checked to see if I was geetting spark and was not. After one try the dash board said engine may not crank because of theft. Then went a way after "jiggling" wires at fuse box. There are no popped fuses. I was told it may be the VATS. So I tried moving the steering coloumn up and down and shifting gears but no luck. Any ideas?

Is this a Northstar powertrain, or a 4.9L? They are completely different ignition systems. If you had a vats problem, I don't believe you would be able to crank.

If you are not getting the theft message, the vehicle cranks, and has no spark, I would suggest you have either a faulty ignition coil, a faulty cap/rotor grounding the spark to the distributor shaft, or a faulty ignition module. What kind of maintenance has been done as far as tune up.

The Theft Message came on one time but have not seen it since. Its my mothers car and I have been in the Marines so unfortunatly I dont know about the PM that has been done. What I do know is that it has been stolen once but that was 4 years ago.

Like I said previously, if it cranks, and has no spark it is not a theft fault. Just for grins make sure you have approx 40 psi fuel pressure, then look toward the secondary ignition. A coil, faulty cap/rotor, ignition module, can be most of the possiblities. Assuming it has no spark on any cylinder(check more that one). I am not certain if you can have the components such as coil, or module, tested at a parts house. That may narrow it down. If you pull the cap and inspect it, the contact, and the rotor, also briefly crank it and verify at that point the distributor rotates. Sometimes the roll pin for the gear can shear.
