All seems ok now thanks Gav and Jack, pre delivery pump it was. I have learnt that the tank pump hums quietly and the pre delivery pump pressurises the system then stops, A high buzzing noise then it fires up, sweet. hope this helps someone else.

Changed the pre delivery pump and the new one made a whole different sound to the rattly intermitant old one and again she fired up straight away and again this morning. I am confident job done this time, fingures crossed. Nothing worse than an intermitant problem, makes the whole fault finding so much harder. New, fuel filter, air filter (looked black so just changed it) and pre delivery pump, she should run nicely now.

Ok the latest, changed the fuel filter and it fired up, strange this. Now, the pre delivery pump at one stage wasn't working when jacked up and then it did when on the ground. It is quite vibratey to the touch and quite noisy, how is it suppose to sound? thanks Rob

It seems to run great Gav. The son has been speaking to one of his apprentice pals who says it could be the fuel filter, he ran it down to the light when on a long journey last week , but when he filled it up proceeded to to do 120 miles. He tends to think that air could have got in, i'm not convinced. He also says we shouldn't crack the injectors as the pressure can go through concrete, but this was just a wee spurt if anything.

Well we were ok for a while. The car wouldn't start again in town last night so we did the same thing and she fired up and got home. Went to start it again this morning and again wouldn't start but there didn't appear to be as much if any fuel coming through, could this be the fuel pressure switch? thanks Rob

Well all hail to the Gav, I cracked an injector this morning, turned the engine and fuel was present, tightened it back up and she fired instantly, air, jeeesssuuusss what a relief. Thanks also to Jack for the info, that would have been my next call. Thanks folks really appreciate it and the son is overjoyed too. Rob

Thanks so much guys, I am a real novice at this and my son is frantic he may need to take this to a dealer. I asked our usual mechanic to come out but wouldn't so end of relationship there after a good few years of giving him business. GAVHD - is the leak off pipe obvious? I take if fuel comes out then it could be the fuel pressure regulator? Jack Dabsy - He filled up in Edinburgh and did 120 miles before getting home, the car ran great all that weekend and before, weird it should just fail to start the next day, but thankfully it got him home. I will check for a fuel rail valve tomorrow and hope I can find the up lift pump if not. Will post my findings tomorrow guys, thank you.

Help please! My son has a 320d e46 2005 and won't start: please bear with me: He did a run to Newcastle last week and the car was great, went to start it the next morning and wouldn't fire up. I've done some research already and we have checked: Fuse in the engine bay right hand side under the black cover - ok (not sure what this one is) Pump fuse no. 54 in the glove compartment - ok All the relays seem to be clicking on and off behind the glove box - ok getting a noise from the fuel pump under the rear seat - ok Pump under the floor of the passenger seat beside the fuel filter - ok Tried pushing some carb cleaner through the air filter to get it going in case it was loss of fuel pressure and although it fired for a few seconds didn't sort the problem and I didn't want to use too much of that stuff on the engine. Questions: Where is the cam sensor and how do I check it? have read this could be a problem but don't know why. Could it be an immobiliser problem? any help much appreciated. When we get to the bottom of it I will post it. Put a code reader on there and reads P3005 which is fuel low pressure I believe. I phoned our mechanic who services the car and he advised to start it with some EZ start or something and that would enable the fuel to get through and rest the pressure. When I did this the engine made a pinking sound and I didn't have the balls to keep the spray going, should I have? thanks in advance.

Hi guys Can anyone point me in the direction of a good fault code reader? It would need to read various modern vehicles. Thanks Rob

Glow plugs?

Thanks this started after a service and the fuel filter had just been changed, thanks anyway. Mechanics tend to blame anything on biodiesel to be honest including worn windscreen wipers :rolleyes:

wow, no one able to help!

Hi Guys, I've had a good look around the forum to see if I can find the answer but to no avail. My son has a 320D E46 and his heater plug light comes on intermittentley and can run sluggish as a result but then goes off and is ok. We replaced the plugs but the problem persists, can anyone give us some advice? Just to note that we use biodiesel as a blend and he mixes 50/50 bio and diesel, I make it myself and am paranoid about the quality of the fuel. I also run an Audi 20 TDI 70/30 bio/diesel with no problems at all.

By the way the SOT-060 lead is for an E46 just in case you need that detail.# Rob

All fitted and works a treat, anyone thinking of adding a Parrot, you need a SOT-060 lead. Halfords being a Parrot dealer and given that the 3 series is one of the most popular reps cars that would need hands free, supprise they don't stock them, Had to go online, Halfords are useless.
