having a starting issues with the Alfa (1.9 jtdm 16v), originally thought it was a crankshaft sensor as the engine is just not firing,.
They were intermittent, but just cant get it to start today.
Luckily my obdII sensor arrived in the post today, looking at this, thinking the issue may be elsewhere.
The demanded Fuel pressure is 270 bar, but getting under 10 bar (whilst cranking). Assume this where the issue lies. (though there were no recorded errors)
It was cranking at over 200rpm ( under 100 rpm can cause issues with the high pressure pump not running), so the starter motor is fine.
So thinking course of action should be:
Change the fuel filter (which is corroded and clearly not been changed of late),
then investigating the fuel pressure regulator (will probably need to be left to the garage).
