My 06 Explorer will not rev up at all. It cranks and idles but that's it. I have replaced the throttle body motor and throttle position sensor. The butterfly swings open with the gas pedal when key is on but not when cranked.

2006 Ford Explorer

Took truck to mechanic. I replaced TPS and throttle body motor according to the diagnostics. Nothing. Took to another shop. Diagnostics said tps and motor snd computer. Replaced computer. Took to ford dealer to flash comp. WOULD not crank. They sai d starter relay and rollover switch were bad. Didnt believe them so told them to check it again. They found those were not bad then they told me throttle body is bad. Now check engine lite wrench lite abs lite and traction control lite are all on. Truck cranks and idles like before. No rev. Starting to question fords which is unheard of for me. Help please info.
