Hi thought id share this one with you . I recently had a few problems with car starting , now when i say starting more lack of starting . First happened outside wifes work key in ignition nothing just flat as pancake left it whilst looking under hood tried again , and away it went we got home . Fine for couple weeks then bam happened again in tesco car park unhappy called mate for a lift home . 20 mins in tried car again bam started no probs . Took it to mates garage he thought it was a faulty fob signal etc . Anyway car fine for few days until taking kids to zoo . Overtaking a car at 60 mph suddenly lost power and got fuel injection fault on dash car went into some sort of mode till it packed in on the kerb . Luckily i wasnt to far from home so pal towed me home . Now key fob was not the problem or my fuel injectors they were fine it turned out to be one of my fuel pumps had packed in . Now bmw said it was injectors and it was going to cost a hat full of cash but with having pal in buisness he confirmed this not to be the case and it was fuel pump so i thought id share this with you for future reference so to speak
