BlowMyWhistle 0 Report post Posted June 14, 2011 (edited) Hi Y'all. My car's stopped.. I suspect the fuel pump? But I'm a bit lost. I've never touched it in 4 years, now I have too... Does anyone have a link to pictures of an e34 rebuild? Atm I can't even get the spark plugs out (hangs head in shame)... I've been told there's only a couple of bolts holding the covers on, but nothing seems willing to move... Car spluttered a bit, and now wont start... Luckily it was just at home. Any links to a rebuild or similar wood be appreciated. Or I'll have to borrow my daughter's e30, for a change... Cheers edit: I can see on real oem, that these covers seem to just lift/pop/pry off, but unwilling to force it. Do the wires that run through, to the coil packs/plugs? Are they attached to anything, or can I gently lever this cover off with my trusty wrecking bar? Cheers Y'all..

BM WORLD 1262 Report post Posted June 14, 2011 there are 2 bolts the hold the covers on which are under 2 plastic caps. then they should just lift off (maybe sleightly stuck if not removed for a long time,sticky rubber seal) sounds like your fuel pump could be at fault , my mates did that just the other week. try banging it to see if it comes to life , easy enough to left out and test it. then you have to undo the 2 or 4 bolts per coil to lift them off unplug them (sliding plug lever) then you can get at the plugs http://static.bmwfans.info/images/epc/MTUyNzAzX3A=.png http://static.bmwfans.info/images/epc/MTQ4Nl9w.png http://static.bmwfans.info/images/epc/MjMzN19w.png Quote Share this post Link to post Share on other sites
BlowMyWhistle 0 Report post Posted June 14, 2011 Cheers for that link, blame my old eyes and my stubborness to wear glasses, saw the same pix on oem, dint see them on the car til I found a torch, cold wet WA day today... $1200 for a fuel pump, or $395 for one that's used, mite have a dodgy relay or something... From my mate Andy at Beemer Motor World, maddington (WA not papakura). He tinkered with my daughter's car, changed a lead, still surging at idle, but better. new set of leads inc the crank sensor?

BlowMyWhistle 0 Report post Posted June 14, 2011 Damn for tinkering.. Pulled the fuelgauge sender out, now can't get it back on, damn rubber groommet, does it just sit there and the jam jar top will screw it down? Can't seem to get it started!! Guess this is how we learn things innit? Quote Share this post Link to post Share on other sites
BM WORLD 1262 Report post Posted June 14, 2011 $120 here for a used pump , same as in 520i 525i 530i 535i etc Quote Share this post Link to post Share on other sites
BlowMyWhistle 0 Report post Posted June 15, 2011 Cheers for that! Checked the pipes in and out of the fuel tank, return is weak flow, good pressure from the outflow side, nearest the rear of the vehicle. So seems I got spark and fuel pressure, at the tank anyway? The fuel filter should have been done last year, looks pretty new... Would it b worth taking the fuel rail off to see if it has pressure at the engine end? Could it be something simple like a relay to the cpu or dme or whatever acronym? If is, how come it has spark? What else does it need? Juice, electricity... I'll keep looking, asking.... cheers.

BlowMyWhistle 0 Report post Posted June 17, 2011 Thanks for that, checked the fuel at the hoses on the sender, plenty of pressure there. better not be anything simple like a blocked filter, I had that changed last year ann I've only done 5000 k's since then.... Anyway it's gone on a trailer to the German, Peter's master motor mechanic, here in Rockingham. He's got a new diagnostic tool, did he say it cost $400k? musta been $40k, could just about buy a house here for $400k Thinking fuel pressure? Very little return from the return hose vs the amount it was pumping. Anyway, as I said, I'm back to work for 2 weeks! Quote Share this post Link to post Share on other sites
twisted 45 Report post Posted June 22, 2011 had a similar issue with my old 540 and it turned out to be the crank sensor. there's a way of measuring it with a multimeter, but i forget what it is. Quote Share this post Link to post Share on other sites
williams 0 Report post Posted June 25, 2011 did it cut out on you while driving or just not want to start? had similar problem with not starting one morning, tried everything, eventually put jumper leads on- pedal to the metal an crank took a while then started has never happened again Quote Share this post Link to post Share on other sites
