yeti-dj 7 Posted August 9, 2008 Hello, after converting my 1.9 205 to mi16 power and it running faultlessly for over a year the other day it decided not to start? If you keep cranking her over there is a smell of fuel and after removing the plugs these were soaked in fuel so thats ok, then checked for spark and all 4 plugs are sparking fine,replaced all plugs,rotor arm and cap as they were due it anyway and still no go, then tried changing the AFM and that didnt help. I then removed the sensor from the top of the gearbox and this was covered in a little gunk so cleaned it and replaced it and then the car started fine!!!! Surely a little bit of gunk on the sensor wouldnt have caused her not to start and this is simply coincidence? No idea how old the sensor on the gearbox is but has anyone else had a problem with the car not starting because of this part, suppose if the sensor is gone then the timing will be a mile out and car wont start. Will get a new one just to be safe, wheres best for price? cheers... Share this post Link to post Share on other sites
GLPoomobile 958 Posted August 9, 2008 I think that may be a red herring (but could be wrong). If the CAS (crank angle sensor - top of gearbox, thick black shielded wire with a 2 pin plug half way along it's length) was duff I'd have thought you'd have no spark or fuel. I'm sure the ECU relies on a signal from the CAS before doing anything. If anything it sounds like it was overfuelling. So possibly the good old ECU temp sensor playing silly buggers.

Richie-Van-GTi 72 2 Cars Posted August 9, 2008 Agree'd, sounds like it flooded and wouldnt start, it started after messing about as the fuel evaporated. A dirty/faulty CAS would stop it sparking and squirting so definatley a red herring. Share this post Link to post Share on other sites
yeti-dj 7 Posted August 11, 2008 Didnt think it was the crank position sensor, seemed far to easy to fix, haha!! Even after leaving the plugs out over night the car still wouldnt start the next morning so it wasnt the fuel evaporating that got it to start, probably just luck that it did... The over fueling idea seems to be spot on though as even after one crank of the engine the plugs are soaked so will try the ECU temp sensor next, which one of the sensors is the temp sensor for the ECU? cheers for the help..
