735i will not start please help

Hi every one im usually in the E39 area but my dad has bought a 2001 735i sport model (same as the 740i ) V8 engine . but we cant get it started . the car was working fine untill the engine and transmission along with the suspension and wiring was removed from the car for repairs to the body to be done and now ,after four months we put everything back together ,the car will start for one or two seconds and then die and im getting engine failsafe and four codes

P0120 throttle / pedal position sensor A circuit pending

P0123 throttle / pedal position sensor A circuit high input pending

P0223 throttle / pedal position sensor / switch B circuit high input

P0103 mass or volume air flow circuit high input pending

the first three CANNOT clear with my Actron cp9580 scanner ,but the last one will clear and return after the first attempt to start .

i have done alot of searching and found similar problems ,i have looked for corrosion at the temp sensor on the thermostat (none ) checked and rechecked the connections at the dme and all other wiring . any help in this matter will be great
