I've got a '96 Taurus Wagon GL, 100k miles with a 3.0 V6 that has a weird hard starting problem. I've read the previous posts on hard starting problems, but they didn't seem to help out my situation.
The Problem: First thing in the morning, the car starts up beautifully on the first crank. Idles fine and runs well. If I let the car sit for 1/2 hour to a couple of hours and then try to start it, it will crank and crank away, but not start. If I depress the accelerator to the floor and release while the engine is cranking, the car will start up, sputter a little and then run fine.
What I've done:
Ford said fuel pressure was OK, as was charging system and battery. They recommended replacing the IAC. Also, they recommended changing spark plugs and spark plug wires. When they quoted 1 hour labor for the IAC, I decided to do the job myself.
So, I've replaced the IAC, the spark plugs and the spark plug wires. The battery was disconnected long enough for the PCM to forget the old IAC settings.
Now, I've still got the exact original symptoms. Cold engine starts great, warm engine cranks and cranks until I press down on the accelerator.
I've tried the "turn on ignition, wait for fuel pump to prime the lines" trick. No help. I've also tried the "turn on, turn off, repeat four times" trick. Also no help.
Should I buy an ODB-II scanner or are there other things to try?
