Hi, yesterday I jumped in my car and tried to start the car, which normally fires up right away, the engine was turning over but it was a different sound, almost like a humming when the engine was turning over, it never started. I checked the codes, Fuel 46 and Fail 46 appeared, can anyone give me any suggestions what it might be and if I could fix it (non mechanic) or things I might check....Please
Thank You Very much...Julia

 

I reckon a repost in teh XJ40 tech section will get the answers you seek.
