My parents have a 2000 Excursion with the V10. 4x4 90k miles.
In the past year or so, we have been experiencing a no start issue. It only does it when it is hot. When the issue first arose, the "theft" light would flash quickly. We thought we had it figured out, that the PATS system had malfunction. So we took out the PCM and had Jody at DP Tuner reflash the PCM to ****** the PATS system. Im fairly sure the PATS system is disabled because if I attempt to check it's status, my AE says there's no communication with it.
So fast forward a few weeks, we drive it a few times, and all seems well. Well now its back doing the same thing again. It cranks fine when cold, but after you drive it a few miles, if you shut it off, sometimes it will crank back, and sometimes it won't. The theft light is no longer flashing either. We replaced the battery, but no other parts than that. Also, I noticed when it does this no start issue, we can hear the fuel pump continuously running. It never shuts off.
One of my dad's mechanic friends says he thinks the PCM is bad. Can the fuel pump be bad, but still sound like its operating? Could coils be bad? As far as I know they are all original. Thoughts?
