Had a full diagnostics check on my zafira and had my crank sensor replaced and two Lambda Sensors about 3 weeks ago because my zafira was ticking over but not firing up but yesterday at a set off traffic lights in Norwich the engine seem to just fizzle out slower than a stall and it fired up after a couple of tries so parked it up while my wife went shopping and called for my road side assistance to help but the guy wasn't sure what was wrong cause he said the fuel pump was working and no engine management lights were on when he used his diagnostic's but again it just was ticking over but not firing up so he offered to tow me 10 miles which was no good because i live 32 miles from norwich so had to pay for another tow truck which was cheaper.but the car still won't fire up today and the car had a full service an m.o.t 6 months ago at ames????any idea's Please???

Despite what you've been told first thing I'd be looking at is the fuel pressure and delivery.
When was the last time the fuel filter was changed?
ever?
Just because the pump is running does not mean there is pressure or volume.
Diagnostics are one test,much better is a waveform output from the fuel pump.
Fault codes are the begining of daignostics,not the end .

do you mean it ticks over ok but wont rev up (NO POWER) IF THAT IS THE CASE and no management lights on it could be a blocked exhaust or cat
