CAR: 1991 DOHC, 187,000 miles, automatic
PROBLEM: Car starts, then dies immediately. Will not run after starting. The start-up sounds normal, but then it just stops running.
HISTORY: For the last two months, Car ran great at 70 mph on the highway. A few times while driving or backing at 5mph, car would die, but could then be restarted immediately. A couple of days ago, while slowing down for a turn, car stopped running. Car then began the problem: start and die immediately. It did it when the engine was HOT, and now does it when the engine is cold.
CHECKED SO FAR: Plugs & wires all OK. Fuel pump "whirrs" for 2-3 seconds when key moved to the "on" position. Oil Pressure builds immediately to proper pressure on the short "start-up." Coilpaks and wiring looks OK.
REPLACED SO FAR: Coolant Temp Sensor, Crankshaft Position Sensor.
WHAT NEXT?: Please advise as to what else might be causing this problem. Anyone's advice on this is welcome.
