I have smart but all this is the same so I put this question here.
help me, I am crazy with car.
SO, I have smart cdi, 2003, 60000miles. Before 4 month I drive on freeway for one hour, speed 120kmh, outside temp around 28C-hot day. Engine get hot to 120C
, so I cool it down and turn off for 10 minutes. When I try to start engine, starter turn over but no fire up. After 20 times cranking engine start with allot black smoke. To this days, I CANT START ENGINE NORMALLY. No smoke, no nothing, but when running idle is perfect, run perfect, never stall. Symptoms: starter turns but no crank. Last two days in the morning outside temp is around 14C and engine start fine but after several minutes driving no start again. Sometimes I can recognize little and several air bubbles in fuel lines but this is not reason for hard starting like this.
1. compression test, 16bar, 26bar, 26bar
2. computer diagnostics OK
3. battery OK
4. starter OK
5. new camshaft sensor
6. injectors tested and is like new (both injection and return)
7. no smoke
8. power OK
9. no oil consumption
10. fuel pressure at idle 240bar, on turn over 370bar (OK i think)
11. new fuel filter
12. new air filter
13. new termostat
What to do people??? I am crazy, I check everything, my pocket is empty.
This low compression on one cylinder is last thing but why engine sometime start ok even is hot???
