Have found out how to hand crank the engine to my 2003 c3 1.4 Hdi desire: Jacked up drivers side of car. With a socket and ratchet I turned the crankshaft pulley which cranked the engine, so now I know the engine turns and need to do further testing on the starter electrics. I made sure the ignition was off and engine out of gear 1st. I want to check out the cause of the non cranking myself because I had just paid another £300 to an Auto Electrician to solve and fit a new starter motor and a push button starter, thus bypassing the ignition switch which he said was faulty. Apparently this caused the bendix not to spring back after the car started and thus burnt out the starter motor. Within six days of getting the car back, I came out in the morning and the car would not start, even after trying to push start it. I contacted the auto electrician who said he would organise something because I couldn't get the car to him. But I have not heard from him since then. So, I want to go through all the tests myself as I don't want to be stitched up.
