Engine Performance problem
1998 Ford Taurus 6 cyl Two Wheel Drive Automatic 110000 miles
It started with the 30 degree weather, but maybe it's a coincidence. Hot or cold, sometimes the car won't start. Cranks fast, no battery problem.
This morning it wouldn't start. Ambient temp about 25 degrees in the garage, but it failed last week after it was warmed up and about 40 degrees.
Couldn't hear the fuel pump when I turned on the ignition. Swapped the AC clutch relay with the fuel pump relay (same Part#) and it started. Maybe another coincidence? Replaced the relay and it still starts OK.
After reading many forums, the IAC (Idle Air Control)sounds suspicious. It has an occasional problem with the engine racing, about once a month.
Other forums mentioned the Mass Air Sensor as a possibility. Would that or the IAC prevent the fuel pump from getting energized?
EDIT: Just tried to start it again and couldn't hear the fuel pump and it wouldn't start. :(
Never got a check engine light, no codes.
have the same problem?
