i recently bought a 02 f150 2wd 4.2. it won't start, but it cranks over. i can't hear the fuel pump engage, so i check all my fuses and relays before tearing the tank out. i also do not think i have spark. If i spray starter fluid directly into the carb it still doesn't fire not even for a short second. Also when i hook a code reader to it it can't communicate with the truck. i tried 2 different readers. 1 more thing i had a truck like this before and i had a PATS key for it. and this one i do not.

also while looking underneath there was a ford mazda transponder hooked behind the fuse under the steering wheel


so no
fuel
spark

some research pointed to the PCM but everything there looks intact.

any tips or ideas are greatly appreciated. thank you
