Resetting a Vehicle Anti-Theft System

This is how you reset an anti theft system if you have the anti-theft light on, or your car is cranking, but you have no spark.

Doing a full reset of the anti-theft system.

Disconnect both battery leads for at least two hours.
Hold the negative and positive leads together for 5 minutes to fully discharge any power.
Put the key in the ignition, but not turned on. VERY IMPORTANT!
Connect the positive lead.
Connect the negative lead in one swift movement.
Wait 15 minutes for the system to fully reset.

How do I reset the anti theft on the car?

this will sound odd, but I was having the same issue, and I tried everything on this forum but I wasn't getting anywhere, but I decided to check all my fuses under the dash and found out on my 2010 Ford E350 fuse #54 fuel pump relay coil, was blown, I replaced it and the van started right up, I was having all the issues of a PAT system failure, dash lights on, security light blinking, and advance track service light on.
