Afternoon all,
I am having a problem with my 306 HDi not starting. There is power in the battery, engine is cranking but not firing. I have checked the high pressure side of the fuel system and getting diesel pumping out when turning the key, so no issues with the fuel system.
I have a handheld code reader and got the code P0403 EGR system malfunction. Now this confused me as I didn't think this would stop the engine from sarting, however, I stripped the EGR valve and cleaned it, checked the solenoid and the wiring. Still wouldn't fire, so had a friend with access to a proper diagnostic set.
There was the P0403 code as well as P0340 camshaft sensor circuit malfunction. I have changed the cam shaft sensor with the same result, not starting. So I have checked the wiring and I am getting a 5v supply when pins 1 and 3 checked with ignition on. When probing pin 3 and 12v+ I'm only getting about 7v instead of 12v. When probing pin 1 to earth I am getting no reading and when checking resistivity between pin 2 and ecu connector I am getting a low resistance reading, so no break in the wires.
Could someone please shed some light on this as I'm now stuck and can't see how to proceed.
