Several months ago, my XJ began to get hard to start. As time went on, it became more difficult. Eventually it got to the point that a cold start was sluggish, and a hot start (after pumping gas or something), was down right iffy. It would always start, but I could smell raw fuel afterwards. Now if I let it sit idle for a while and it gets hot, it will die off and be impossible to start for thirty minutes to an hour (after it cools down a bit). A lot of times after starting it warm, it will run really rough and backfire through the throttle body.
Things I have done recently: fuel injector cleaner, plugs/wires/ dist. cap/ rotor button, cleaned throttle body. Fuel pump is about three years old, and the sensor under the distributor cap (can't remember the name) was replaced about two years ago.
Reading in other posts with similar problems, I am thinking maybe a sensor on the TB (MAP, TPS), or possibly an oxygen sensor. Also, thinking maybe an issue with timing, or exhaust, or possibly ignitor coil.
Any insight or thoughts would be greatly appreciated.
