I have owned an 89 240DL, gasoline, only 190,000km for last 2 years. Problem is...Car has always started first try but on occasion, maybe 5 or 6 times on separate occasions, it will crank but not fire or turn over and start. The only common factor seems to be that this happens after several short trips starting several times, or like the other day when it was close to 30 degrees celsius and car was only off for 30 minutes before trying to start again. Just wouldn't fire at all for several tries. Thought it wasn't going to go until it finally fired and started. When I pressed the gas pedal after it had started it made a nasty squealing sound for a few minutes (only when accelerator was pressed). Car started fine after sitting overnight. My question, is this just one of this car quirks or should I be concerned? Any ideas?
