I bought it at an auction and I have the key but no key fob. When I turn the ignition nothing happens but it will try from the fuse box, but will not start still. Possible anti theft block? I have tried to reset it by turning the key 8 times and waiting 10 minutes but still nothing. What Is wrong or how do I reset anti theft or bypass it?

Hi,

I'm not sure I understand what you mean by it will try from the fuse box. Please explain. Is the battery fully charged?

Here are the directions for anti theft access, but it requires a diagnostic system to perform:

SPECIAL TOOL(S)

NOTE:
- The security access procedure is utilized to obtain passive anti-theft system (PATS) security access. PATS security access must be granted to erase ignition keys, enable/disable unlimited key mode, and enable/disable the spare key programming switch (PID SPARE_KEY). The security access procedure invokes an inherent 10-minute time delay prior to granting security access during which the diagnostic tool must remain connected to the vehicle. Once security access has been granted, a security access command menu is displayed which offers various command options.
- Once security access has been granted, multiple security access commands should be executed (if necessary) prior to exiting the command menu. This avoids an additional security access procedure and the associated 10-minute time delay.

1. From the diagnostic tool Ford Service Function (FSF) card, enter PCM. Select SECURITY ACCESS. This procedure will take 10 minutes to carry out, during which the ignition must be in ON and the diagnostic tool must be connected to the vehicle.
2. After the 10-minute security access procedure has been completed, a new menu will be displayed with command options. Select only those functions necessary before exiting out of this menu. Once exited out of this menu, the security access procedure must be repeated again to carry out additional commands.

Please keep in mind, you could have other issues. The starter could be bad, the relay, and so on.

Let me know if this is what you already have done.
