2.00 Diesel Turns Over But Won't Start

[welly]

Hi please can someone shed some light on what's wrong with my mondeo it's a 2.00 diesel on a 59 plate i've had no trouble with it at all but I tried to start it this afternoon it turned over ok but would not start,one of my neighbours said the key might be broken causing immoberlizer problems so I tried my wife's key the same thing happened and a message on the dash said engin malfunction I've tried a few times and still the same, I looked in a manual but it just said take it to dealer hope someone can help .

hi welly lots of things can cause this but first thing to check is all the fuses, if a fuse to the ECM or fuel system blew when you turned it off it won't go if all the fuses are ok you really need to get someone to scan/code read it. i do know they suffer from crank sensors and a duff dual mass flywheel can cause probs too try starting with in gear like 2nd n bring clutch pedal up slowly if it fires up its your flywheel. it could also have a crack in a fuel pipe do you smell fuel? if you do when you've fixed it you may need a mechanic to bleed the system don't go turning it over n over you'll knacker the high pressure pump. also under no circumstance never ever try to tow start it can cause irreparable damage
