good old ford lol, try looking at the crank sensor its located at the front of the engine tucked in right hand side of exhaust manifold and gearbox, two pin plug, i have also known these to have no end of faults with the fusebox.
easy to remove, and solder the connections inside they all suffer eventually, if your not to handy with cars i recommend taking to a auto electrician, easy if you know how. Good luck Davelee

Hey Tim take a look at this, will this help ?
SUBJECT:
No Engine Crank Or No Engine Start Due To Electronic Lockup Of The WCM / SKREEM
OVERVIEW:
This bulletin involves the replacement of the Wireless Control Module (WCM), and if
equipped, the replacement of the Electric Steering Column Lock (ELV). The WCM is also
referred to as the Sentry Key Remote Entry Module (SKREEM).
MODELS:
2007
SYMPTOM/CONDITION:
The customer will experience a no engine crank AND a no engine start condition. Also, the
remote keyless entry (RKE) system will not operate. This condition may be due to an
electrostatic discharge (ESD) from the ignition key into the Wireless Control Module
(WCM), causing the WCM to electronically lockup. This condition may occur more
frequently in dry and/or cold weather conditions where a sufficient electrostatic charge is
more easily produced. This condition is corrected by the replacement of the WCM
DIAGNOSIS:
1. With the condition present (i.e. the vehicle in the no crank / no start condition), connect
the StarSCAN® scan tool to the vehicle.
2. Turn the ignition switch to the “ON” position, and power up the StarSCAN®.
3. If the WCM is electronically locked up, the StarSCAN® will display the WCM as being
“off bus”.
4. If the no crank / no start condition is present, and the WCM is “off bus”, then reset the
WCM by temporarily removing the IOD fuse (with the key out of the ignition switch),
wait for 10 seconds and then reinstall the IOD fuse.
5. With the IOD fuse reset having been performed, verify that the vehicle will now crank,
start, and run.
6. If the condition is temporarily corrected by performing the above steps, and if the part
number of the WCM is earlier than the part number of the WCM listed in the part
reference table in the Service Bulletin Parts Required Section below, then perform the
Repair Procedure.

Yes - sounds like a Pump fuse, relay, or a pump...When you cycle the key (off-on-start-on) do you hear the pump running?
The fuel pump fuse may be under the hood with the other engine fuses - and it well may not be -(there is an accessory fuse box that has all the fuses for the inside accessories in it - located in the passenger compartment somewhere)- also check the kick panels at the drivers left foot and the passengers right foot -(If they pop off easily - The fuse box plastic cover will pop off easily, not attached with screws - so if you see screws or nuts, it won't be there) Look up under the dash on the drivers side, and also lastly check in the glove box- If you cannot find it, I'd see if I could find a Mazda "lovers" web-site - Often they post what is called "component locator" information, that would tell you exactally where it is (Normally you have to pay for access to that information - gotta love the web), or you may be able to locate a electronic owners manual there as well which will definitely tell you ...Best of luck and hope that helps some....
