Engine Cut Out, Now Own't Start

[Tigerryes]

Hi guys, again. 2002 c5 2.2hdi manual.

Right had the car a few months now, no probs. Little while ago was out for a long drive and dropped down a gear and put foot down to overtake, suddenly got the esp/asr anti pollution message but no loss of power and no limp mode. Carried on to destination and even though the warning was still showing the car started and ran fine. After a bag of chips listing to the radio, started car and all messages had gone and car was fine.

Recently done a de-fap, ecu mapped etc, all done fine. Done some 80 miles or so, no probs.

went out today, done another 80 miles, on the way home come off the roundabout and gave it some welly and fine, about 3 miles later the engine just cut out, esp/asr message came up, not even a rolling cut out like fuel had run out, just cut straight out at about 50mph, like someone had switched the ignition off. Pulled over and the car hasn't started since. Checked for fuel at the front, plenty there. It turns over fine but it's not even trying to fire. Got the pump hum at the back when switch the ignition on so that must be ok. Called rescue, no diagnosics equipment with them, but checked the battery, thats fine. Fuses all seem to be ok. Recovered home. Been a couple of hours now and still not starting.

any ideas would be great, hope to tow to a friends tomorrow for a plug in but not lexia so would guess its not going to tell me much. I really can't afford to take it to a citroen garage, plus i wouldn't be able to get it there.

thanks in advance

Did you get anywhere with this. If not, dose it crank but not fire? Where are you?

A diagnostics article started in September Car mechanics says crank position sensors can fail like this - early signs of failure are when they are hot the engine will cut out but once cool will start again. No fault codes will be given and the engine just thinks the ignition has been switched off. The fuel pump will run initially when the key is put in but then stop. No mention of ESP/ASR though. The sensors are not that expensive so could be worth replacing or at least checking.

According to the Haynes manual, on early 2.0 hdi engines (SOHC), the crankshaft position sensor is on the gearbox bellhousing directly above the flywheel (so next to the engine block) and is held on by 1 bolt.The air cleaner parts may need to be removed to gain access. On later 2.0 hdi engines (DOHC) the sensor is next to the crankshaft pulley at the timing belt end of the engine and held on by 1 bolt - the right wheel arch liner may need to be removed to give access.
