Starting problem v70 d3 auto 2010
Hi can anybody help with a ongoing problem I’m getting starting my car.
First time it wouldn’t start was 2 months ago.left it overnight and it started up was fine for 2 months now it’s done it again. Rac guy came out and said it was crankshaft sensor. He sprayed some easy start into air box and it started. He said I have no signal at crank,so I fitted a new sensor and the car started up I let it run 20 mins turned it off and on again and it won’t start again. I left it overnight tried it this morning and it started for a second then cut out. I’ve pulled the fuel line off the high pressure pump and cranked it over to see if any fuel is getting to the high pressure pump but no fuel came through. Could it be the sender in tank pump?or could it be ECU related. Thanks Steve |

Hi Steve
I have had problems in the past wit sensors and changing them has fixed the problem for a while then fault returns. Might be worth looking at the wiring to the sensor as it sounds possible that you have a bad connection / wire rather than bad sensor itself. Good clean of the connectors in my experience is a good starting point. I believe that the ECU might not fire up the injectors if there is a problem with the crank sensor as it will think the engine is not turning. Just a thought , but sounds the actual fault heads back in the direction of the crank sensor rather than fuel related. |
