Empty flow controller/air flow meter

Good evening together. my fat guy left me for the first time last night. and is still standing, because no one comes up (snow, ice, too parked) have described my workshop the case that I type on petrol pump (behaving as with my old kadett – at the lower speed range happens nothing, stutters and can just so on tours at fully pressed pedal. pump is however excluded, they sparks.) . the kfz ́tis made immediately responsible for it because LLR or LMM ( o hne test – is still parked) . now my question. can one of the two parts cause the motor to no longer start? mfg driftersdt
