(G) mk2 uno turbo starting problem???

hi there lads. right ive got a problem with my uno turbo. it wont start, its nearly starting btut wont fire up. theres a spark, weve checked the air flow meter, new distributor cap, new plugs, had an auto electrician out and he seems to think it is crank sensor. any ideas, thanks Gary.

could be. although I'm not sure it has one! although TBH I haven't got up close and personal with mine yet. just acquiring parts for a minor overhaul when the time comes

unplug the airflow meter and try starting it, if it runs but sounds like a tractor then you have a air leak inbetween the airflow meter and the intake i.e a split boost pipe

hey mate got your pm, try and get a known working crank sensor and try it.

check everything is plugged in properly especially to the ignition coil, Louis on here has a mk2 which he is breaking for spares if not try on turbo collective theres always people breaking them on there

If it was the crank sensor you'd be unlikely to get a spark, they also have a flywheel sensor so you need to check both. If you've got a Haynes manual it will tell you the resistance of both sensors, also check that the sensors pulse when cranked. Are your injectors working if you've got some noid lights you can test the injectors are getting a signal. Is your electric pump working?

Is there fuel getting into your rail? usually if its firing the odd time its the afm but it definately sounds pretty electrical. Did it cut out during driving or had it been left stood a while or what?

hi mate, i drove the car back from london it was fine, it was stood for about a week, it started missing a little wen it started then i left it another week and it wouldnt start at all. wot do you mean afm? thanx mate

AFM is the Air Flow meter

That is wierd. Cant really comment without looking at it tbh. Check spark and fuel first, if theyre both there then that points to AFM, pick one up regardless cos theyre about £30 and its always good to have a spare one cos theyre a common problem. If that still doesnt start it, do a compression test. If compression is fine, uve fitted a new AFM and the engines getting fuel and spark and its STILL isn't starting.......youve stuck diesel in it!
