Engine Performance problem
1993 Ford Tempo 4 cyl Front Wheel Drive Automatic 89,785 miles
I have had this intermittant hesitation/stalling problem for a few months now. When it first showed up, it was suggested that I change the fuel filter, which hadn't been touched since I owned the car from 1994 purchased used with about 12K. This change seemed to help for a bit but the problem has shown up again. Most of the time, when the car stalled, it would restart without a problem. On a couple of occassions when the car stalled, it wouldn't restart for a long while, once it was 24 hours before it would fire up again. At present the car will not start. Usually when I go to start it up you get the lights on the intrument panel & the tone for the seat belt as well as a whirring sound, I assume is the fuel pump. Hearing this, I KNOW that the car will start. If I do not hear this whirring sound, it won't start. I haven't been hearing this whirring sound lately on my attempts to start, and it will not start. Today I purchased an Equus brand code reader for Fords @ just under $30. I plugged it into the EEC Test plug and noted the generated codes under KOEO mode. I got two codes, #116 & #543. The first code from the manual said that the coolant temp was higher/lower than expected. Well the car's been sitting for the last week, what did it expect the coolant temp to be! ; 0) Anyway, the second code said " Fuel pump secondary circuit fault". I'm trying to find out exactly what that indicates. Is my fuel pump shot? Is there anything else I can check before getting it towed to a mechanic? Any help provided would be greatly appreciated!
