Hi
Posted some time ago. Haven't been able to solve the problem. D40 became progressively harder to start over time.
Lot's of winding it would start. Took longer and longer.
Enough smoke to see from orbit.
Previously - once started- would start normally straight away. Be Ok - then after 4 hours would not start again. Thought it might be fuel problem. Tank out all lines checked etc. New fuel filter. New glow plugs. New boost control solenoid- new MAF. Intercooler clean.
Now it will not start at all from winding. Occasional attempt but no go.
Can roll start as long as the speed is high (used to be slow) and use 2nd gear with wheel lock-up.
Once running it will run beautifully at 2,000 revs all day (no load).
Shut down - it will not start without high speed roll start.
Eliminated fuel and glow plugs because hot and no time to lose fuel.
Now at idle it seems to "miss". This was not occurring before. Unplug turbo diaphragm suction line and seems to run better at idle.
Drive it and it hurls out smoke (loss of power etc) until 2,500 rpm - then it seems OK.
I had hoped the progressively worsening problem would reveal some catastrophic failure - but no.
Did have ERG blanked off. Have removed that. No difference.
Could this be injectors? Computer? Throttle position sensor? Very reluctant to invest in new injectors as I have found most other problems are quite simple - albeit hard to find.
This has driven me nuts.
