Bad starting fixed by changing the Starter Motor: Hi, I have a 2003 2Ltr HDi with 105K on the clock. Last winter it started to be difficult to start. Things got better with the summer, but it still took longer than normal to start, especially when cold. Finally the car refused to start when I was at a supermarket; a nearby Renault garage tested the battery and said it only had 50% capacity left, but that was unlikely to be the cause of the failure to start. They also jumped the car, but without success. However, when the Rescue guys turned up the next day, it started first turn of the key! As I was abroad, I took it to a Citroen main dealer who ended up changing the fuel rail and fuel pump sensor. That didnt fix the problem either, but they then said all the pressures were normal so it must be the Starter Motor - which made no sense to me as the starter turned the engine over at about 300 rpm when hot. In the end the car would only start with easy start. A new battery fixed things for a few weeks, then back to easy start. Most garages said it was probably an air leak or an injector problem. However, the original garage was very insistant that it was the starter motor and that they had seen this problem before with the C8. It made no sense, but I decided to investigate further:- The battery voltage was dropping to 9 - 10V when cranking, and the starter was getting very hot, so I changed the starter, and it now starts first turn of the key. The new starter sounds very different from the old one, which used to crank the engine like an old bendix starter, so I guess there was something wrong internally; the bearings were also shot. I can only guess that the internal problems in the Starter, put such a drain on the battery that the voltage dropped too low for the engine ECU to work and turn on the Injectors - certainly once the car started it always drove completely normally.
