For the last 10 years or so, my '99 XJ has had the issue of the engine momentarily cutting out on a very hot day at highway speeds (100 kph). It doesn't get very hot where I live, except for a few times a year. On average, the problem occurs once a year. When the engine cuts out, it feels like someone is stepping on the brakes. The duration of the stall is about 1 second, then the engine resumes.
In the past, I had upgraded the ignition coil to an ACCEL branded one, but it didn't fix the problem. Replacing the spark plugs, wires, and dist. cap didn't help either. I measured the resistance of the 6 ignition coils when the car is cold and get the expected 12 ohms. I still need to measure them when the car is hot.
Anyway, I am leaning towards needing to replace the fuel pump module (pressure reg., pump, fuel filter, strain, etc). That is a rather involved job for the occasional home mechanic with the XJ being the daily driver. But before I begin this horrific task, I was wondering if anyone else had any other ideas as to what the issue could be? If you think it's also the pump, would Delphi be the best replacement brand?
I am the original owner of the '99 XJ and generally have had the habit of running the tank nearly empty before filling it. So I've been doing that for 20 years. I'm guessing that this caused substantial sediment built-up in the fuel filter or pump and running the tank low caused the pump to heat up leading to its wearing out.
Thanks!
