hi guys,
i have a V reg 306 HDI bought about two weeks ago know and today it has died. Its been playing up for three days not starting or cutting out and not going again.
Anyway before anyone says try reading the forum i have spent two evening reading and not come across what im looking for so hoping someone can help please.
I have plugged into into diagnostics and got fault code is P0230, yes that dreaded one.
Anyway checked the lift pump and its not priming, so wired it up to a battery and it works. So i then checked for a live on the plug for the pump which is the blue wire or marked p+ on the pump, which is showing no voltage.
So i then went to the engine bay, checked all fuses which are okay. I then checked the inertia switch which has a 12v supply so from this i decided the fuse in the box was okay.
this then lead to the relay behind the ecu, brown one. This had already been rewired and has individual wires to the relay. I have tested connector 8 and found there is 12v going in.
However this is where my problem lies, i then removed wire 4 (for the lift pump) tested the pin for this and its only reading about 3v?
what i would like to know is should this still be reading 12v here as obviously i need 12v at the pump and it drops to about 10v cranking.
I believe i should but would like to double check with someone before i go buy a relay from pug to see if this rectifies the problem.
All help is welcome and i hope this makes sense
thanks
dan
