I'm working on a 2000 Lincoln LS V8 for a family friend. I've owned a few different LS models over the years and am pretty familiar with the systems and how they function together. This one has me stumped though.
The issue popped up overnight. They parked it, went out the next day and it wouldn't start. Unfortunately, they took it to someone else to have it looked at initially. The guy had no idea how complex the CAN-BUS system in the LS is and gave up after replacing the fuel pump.
I got the car towed to my house and started looking it over. The first thing I noticed was no priming from the fuel pump. It will not turn on at all. I checked fuses, grounds, etc. and found no obvious issues, but I have yet to further diagnose this.
The reason I haven't diagnosed the fuel issue further is because of a data link error not allowing my OBD diagnostic tool to connect to the cars network. I have used this tool on two other LSs, so it should connect to the system. Also, the message center displays "Fuel Computer Data Error" and "Engine Sensor Data Error". I did some quick research and found that this could be caused by a bad REM, PCM, or instrument cluster. I've already tried a good used REM from another LS I owned and it made no difference.
I was hoping someone else has had a similar issue and could give me an idea of what was the cause. I'll continue doing some diagnostics when I have time, but any help would be appreciated.
