Engine Compartment fuse panel ( driver's side fender ) relay 301. Layout with numbers should be on the lid ( numbers only, not the functions ).

If you did not get an owners manual with your truck ( purchased used / lost ), you can download one from Ford in PDF format:

Makes it real quick to search for keywords.

This usually means there is a transmission related fault. There is probably a error code stored, and your transmission may be in limp mode; usually 2nd gear only. I don't know if Autozone can read trans codes. This may be a dealer only repair. Have you checked your transmission fluid?

Important: Thoroughly wash all contaminants from around the electric hydraulic control unit (EHCU). The area around the EHCU MUST be free from loose dirt to prevent contamination of disassembled ABS components.
Disconnect the three electrical harness connectors from the electronic brake control module (EBCM).
Important: Make sure that brake lines are tagged and kept in order for proper reassembly.
Disconnect the 5 brake lines from the brake pressure modulator valve (BPMV). When looking at the brake pipe port face of the BPMV, the ports are assigned as follows:
Upper Left--Left Front Output.
Upper Middle -- Right Front Output.
Upper Right--Rear Output.
Lower Left--Master Cylinder Secondary/Front Input.
Lower Right--Master Cylinder Primary/Front Input.

When it will not start with the key, is this a crank no start issue ?

If you turn the key from off to run ( do not start ) does the theft light on the cluster go out ?

If not, try a different key. I am working from an assumption that the PATS key is not registering with the HEC for some reason, this is why the try another key. The remote start has a PATS bypass

Please post back with the answers to the questions, and the results of the 2nd key testing

code P1747 short or failure in EPC solenoid circuit ( EPC = electronic pressure control solenoid )

code P0743 TCC solenoid circuit failure ( TCC = torque convertor clutch solenoid )

code P0750 SS1 solenoid circuit failure ( SS1 = shift solenoid 1, first gear )

code P0755 SS2 solenoid circuit failure ( SS2 = shift solenoid 2, 2nd gear )

check the wiring harness going to the transmission sounds like it may have come loose from the holding clamps and has gotten into the exhust it would be hard to belive that all the solenoids failed at the same time but stranger things have happened. if the wiring looks ok check the plugis on the transmission if they look ok its time to go inside the transmission.

You can have very bad COP Ignition Coils without a Mil
Lamp on dash

You can also run Mode #06 on professional scan tool software,
to look at cylinder misfire counts,but need to have someone
drive it, while you look at data.

The EGR Valve or other egr items, could cause the uphill
thing, as your in a high vacuum mode & the coils will break
down as well

I wouldn't throw around the word diagnostic, as your only
looking for stored data, Generic or MFG --with a code reader
or professional scanner,that is no big deal or any computer
involved

O2 Sensors get replaced every 100,000 miles or so,&
yours may have never been done

You obviously need to start will new spark plugs,OEM
config,not some fancy thing with prongs,they won't work
in most fords.

Make sure there is no vacuum leaks anywhere including
exhaust leaks before the converter.

Check PCV Systems is tight & works

Check TPS Voltages

Test,don't replace anything,ever,have to fail a test to
need new parts,except plugs,O2,gas & air filter.

The easiest way to do this is straighten the steering wheel first Brandon. Next is to walk to the back of the truck and eye ball the left front tire from a looking from the side of the back tire. If that one is straight ahead before or after you adjust it, Now check the passenger side the same way.When both look straight, now take a tape measure and measure the distance from the center tread on the right front tire to the center of the left front tire.Say its 61", now do the same behind the front tires. It might say 58". You want to end up with the front measurement being 1/4 of an inch smaller then the back.
