156 start problems ?!
Hi,
Last week, for the 2nd time in a few months, my 156 didn't start at once. The start motor was running, the distribution belt was running, no error lights shown on display, but the engine didn't start. I waited a few hours and tried again, but still with no result. Then I decided to keep the start motor running with full throttle. After aprox. 5 seconds, the engine did come alive, very slowly. A few seconds later it was running stationary. There after, each new start was performed without any troubles. Since the error is not reproducible, it is very hard to find the cause of this mal functioning. My car dealer checked the Motor management Computer, but there were no errors logged. He had no idea what might cause this error. Anybody any suggestion what the problem might be? -- Berry http://bere-design.tk |

Sound like a bad earth or other electrical connection...........

Sounds like the spark plugs were wet with unburned fuel and no spark was possible. By keeping the accelerator pedal on the floor while turning the engine over, you added lots of air to the cylinders which dried out the plugs and allowed you to start the engine. -- Simon Mason Anlaby East Yorkshire. 53°44'N 0°26'W http://www.simonmason.karoo.net |

Hmmm, sounds reasonable. I know the scenario from back in the 80's and
didn't expect to be a possible scenario these days, with the use of advanced motor electronics. Any suggestions how I got into this situation, in other words, what can I do to prevent my sparkplugs being drowned with fuel? If this is the case, is there another practical way to solve this problem?

I suspect that this is not actually the problem. As you surmise, modern electronics should prevent this from happening, but if it did, I'd think there was some kind of sensor fault, either low RPM or cold start. -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l (Really) Sprint 1.7 75 2.0 TS Triumph Speed Triple: Black with extra black bits www.cuore-sportivo.co.uk |

I agree it shouldn't happen now, but maybe if you revved your engine and immediately turned the engine off, this would have left some unburnt fuel in the cylinders. The fuel management system cannot do anything about this if the engine is off. Just an idea. -- Simon M. |

I know it does happen with the old V6s, but I'd hope that things had advanced a bit since then -- Catman MIB#14 SKoGA#6 TEAR#4 BOTAFOF#38 Apostle#21 COSOC#3 Tyger, Tyger Burning Bright (Remove rust to reply) Alfa 116 Giulietta 3.0l (Really) Sprint 1.7 75 2.0 TS Triumph Speed Triple: Black with extra black bits www.cuore-sportivo.co.uk |

Well gents, the only possible thing that might had happened (but I am not
totaly sure about that), is that prior to the described malfunctioning, I started the car to drive it 8 meters further (in front of my garagbox into my garagebox), and stopped it. So, a short (~6s) run of the engine was executed prior to the described mal functioning, a few hours later. The sparkplugs, btw, are brand new (changed 10 months ago, regular service issue at 100.000km).

Is starting the engine with full throttle still the best way to overcome this problem, or does a start with no throttle resolve the problem as well ???
