My 33 16V Sportwagon suddenly would not start one morning. Up to that point the car was running perfectly except that the rev counter started bouncing around. I have battled for many hours to get the car to run to no avail. The spark is strong, the pump runs, I can smell fuel at the exhaust but it will not run even when towed. There appears to be power on the injectors all the time when the ignition is on. Does anyone have any ideas?
