Engine Performance problem
1996 Lincoln Continental V8 Two Wheel Drive Automatic 135000 miles
'96 Continental, 4.6L V8, 136,000 miles. Drove ~ 100 miles, city & highway. Once, after starting the car after it sat in a parking lot for 30 minutes, it wouldn't idle, stumbling and stalling. Had to rev engine, maybe 1/2 throttle, to get it to move. After it got going, it ran fine the rest of the day. The next day, it cranks but will not start, doesn't even try to fire. Scan tool passes; no codes. 1/2 tank of gas, fuel pressure is 37 psi at the schrader valve on the fuel rail. Inductive timing light shows no spark at plugs. PCM relay is ok; swapped it with the blower motor relay to test it. Fuses to the PCM are ok. PCM supply voltage (B+) and reference voltage (5V) is ok; checked at the PCM wiring harness.
