I have a 2004 Peugeot 206, 1.4 Lt. The engine failed whilst driving and after I stopped and I tried to start the car, it couldn't start. My mechanic diagnosed and said it was due to damage on fuel pump. I have since replaced fuel pump and also replaced the alternator cos it was also overcharging. After all these troubleshooting, it still cud not start so he discovered that some teeth on the timing belt we broken. We replaced the timing belt. After that car still couldn't start. He discovered that the valves had bent. That was fixed. The car started and he took it for a test drive fine but after a while after switching off the engine, the car failed to start again. Now a further diagnosis revealed there was a problem with knock sensor. I NEED UR HELP TO ESTABLISH IF I WOULD HAVE TO BUY A NEW ENGINE? Will the car ever be completely okay to drive?
This isn't a vehicle that I have any info on but judging by the sequence of events here, it appears the technician has made a number of mistakes and misdiagnosis here. It started out with a misdiagnosed fuel pump and then not being aware that a broken timing belt could lead to bent valves. A bad knock sensor will not prevent a engine from running so I think he is still have diagnostic issues here. You might want to think about trying another technician.
