Hello My 355 berlinetta died on the high way to day. It just lost all power when it was enganged in gear. I could rev the engine in neutral. I tried to start it again but it didnt even crank over. I waited 15min an suddenly it started. After 2km it stopped again. Same problem. Waited 15min an it started. I got the flashing slow down light, ABS and Airbag light before it stopped. Have anyone experienced this kind of problem before?
The car is a 1999 355 berlinetta. 5.2. capristo exhaust, red interior, titanium gray, 6-speed manual gearbox.
Sorry to hear about this. I've neither experienced this not heard about it. Some possibilities that I am thinking about are 1) main Motronic ECU failure 2) Alternator is on its way out
Was your slowdown light on steady? When it died did you still have some power and it slowly got less and less until it died? Which may indicate fuel problems or was it more like your original post and like electrical one sec its fine then dies? Its possible the battery failed, did your bat light go on? Poor ground, low voltages can cause weird stuff.
Thanks for the answers. im not shore if i got a steady slowdown light or if the battery light was on. It was more like the original post. I will check the battery and ground.
IIRC, if the cat thermocouple indicates a clogged or seriously overheated cat, it will shut off fuel for a cool-down period before restarting. Maybe in owner's manual? Check manual. Use laser thermometer on cat entry and exit, both cats for consistent temps, then suspect electronics.
When you get a cluster of many lights like that, it is usually an electrical problem or lack of. Check the wires going into the alternator plug. I believe its a green plug. There is one wire in there just before it goes into the alternator that tends to fray and cause intermittent charging. Also check the ground strap from alternator to frame. Might even be a faltering alternator.
I have a 1995 F355 and experienced something similar when my alternator went out (twice). The first and easiest thing to check is the output of the electrical system. Put a multimeter on the two posts under the right side panel in your engine compartment. You should be getting 14+ volts registering when the engine is running. It will drop down to 12+ when the fan(s) kick in. With the engine off, your battery should be registering 11-12 volts output as well. While the previous posters were correct in stating that it could be a bad ground or other related electrical issue, this will at least isolate the cause. I rebuilt my alternator with new parts (in place) and have since solved the problem after discovering that the after market stereo system installed by the previous owner had been wired wrong, thus frying my alternator. Hope this helps, Henry
sounds like alternator needs replacing, my car did the same thing not long ago. we found a toyota alternator (same make to ferrari one) that was a perfect fit.
Be more specific. you can't say a toyota one fit without giving part numbers and what toyota its from. whats with the secrets.
sorry guys, wasn't being secretive, i have to check with my mechanic to see what the replacement alternator was. i was told it was a denso alternator from a toyota land cruiser. when i find out the part no. , i will let everyone know.
Thanks for all replays. the problem was the alternator. new one is installed and the car is running again
This one looks like it could be it?: Amazon.com: 100% NEW ALTERNATOR FOR TOYOTA LAND CRUISER LEXUS LX470 4.7 4.7L V8 ENGINE 1998 98 1999 99 2000 00 *ONE YEAR WARRANTY*: Automotive
