My 220 CDI (W203, 1998) has problems starting, finally I got the fuel issues worked out and now she does not want to start. I have hooked up a light on the fuel injectors and noticed that sometimes it is blinking and sometimes not. Now I could be wrong but I thought that it should be blinking constantly for the car to start. Does anyone know if this problem is due to a faulty camshaft sensor or should I be starting to think on a new computer?

I've had a similar problem on a Jag X Type (Erratic injector pulse). It turned out to be a broken wire in the connector to the ECU.

Had simliar problem on cdi sprinter, loom had rubbed through and was shorting out, diagnostic check should locate your problem.

poor starting

HI

Most likley cause is failed injector causing fuel pressure to be too low

As above, or fuel line o-rings leaking air into the system.
