On Saturday, during a splendid drive through the Colorado foothills, my newly finished '73 914 1.7 liter quit without any warning. No coughing, no sputtering, no lurching.....just quit at about 60mph. Not a hot day, no warnings. On the roadside I found no loose wires, no melted wires, no outward signs of distress. My fuel pump is located up front, so doubt it was vapor lock. After dragging it home, the next morning I tried to start it........and voila, it started up perfectly and ran like a charm. My local pro looked at it this morning (Monday) and after testing things thoroughly, found nothing amiss. He did say that once in great while, the electronic ignition inside the distributor cap goes bonkers, perhaps from heat and the car would die like that, then start later. Those parts are new (Pertronix),. Anyone else had this experience? Thoughts? Suggestions?
Thanks! |

If it just dies without warning, I'd certainly be looking at electrical / ignition issues.
Fuel starvation would cause bogging, bucking, slower death, etc. Mechanical issues would make very bad noises. If you have fuel injection, there aren't many things that could fail that would cause the engine to just stop. There are wires that if they ground out will kill ignition. Tach wire is one of them (purple IIRC). Over heating the electronics in the Pertronics could cause what you are describing. Improper (low) voltage going into the coil/dizzy might cause it - do you have a volt meter in the car? But I bet you have a wire with an intermittent ground, or a bad connection from the coil to the dizzy, or something like that. Zach |
