Stranded: E46 330ci

Recommended Posts

Drove my e46 to work today.... It's still at work....

Turns over beautifully, but won't start.

  • Disconnected battery for 1 minute
  • Tried in P, N, foot on brake, foot on gas (and both/none)
  • RPM gauge above 0 (though below 500)
  • Temp gauge slightly above coldest despite sitting all day
  • It did make a strange whirring noise that increased with RPM in the last few minutes of my drive (sounded like a turbine. Fan clutch is new)
  • I may have ever so gently kissed the car park ramp with the under carriage (low cars...)
  • Radio works
  • Never had any issues starting in the past
  • Can't get to the CPS to check it
  • I should probably pull a plug to check for spark and fuel
  • Key is fairly new

So do I ;)

It's also 6 floors up in a car park building with fairly tight turns and ramps...  I'll go have another go, check the fuel pump and fuses and report back

Fuel pump doesn’t seem to be priming (holding the top of the plug/pump and there’s nothing)

Checked all the fuses in the glovebox relating to fuel pump, DME, immobiliser etc

Can you read the fault codes off of the DME and EWS modules?

Not with what I have on me. I’m catching the train home as I haven’t had dinner yet. I’ll get some proper tools and parts and tackle it over the weekend

As it's turning over, the EWS module is accepting the key, which is a good sign.

My next suggestion would be to turn to the DME and read the codes.

If there's no voltage at the fuel pump, check relay K96 (glovebox). It's ground-activated by the DME (plug 4, pin 10, black/purple wire).

Thanks for the kind offer @kiwi535 but I’m already on the train. (I should have checked sooner). I’ll come back armed with tools, multimeter and a scanner this weekend.

I will be around Sunday if you need a hand. The whirring you mentioned could be stater motor related, motor spinjing but not engaging.

The whirring was when it was running. The starters engaging fine and the engines turning over fine. I’ll head in today with some proper tools and check the voltages and under bonnet fuses/relays

Fingers crossed.

Replaced the fuel pump. All sorted. Thanks to @_ethrty-Andy_ for coming along with a pump.

Good to hear it’s rumning again. Are the pumps on these things relatively easy to access?

Could have been worse - my E39’s pump died in traffic in Auckland... for a couple of days I had a noise which I thought was a noisy pulley, worst part was it was booked in to get looked at later in the week.

@NZ BMW yes, pop the lower back seat up, 4x 10mm nuts and it’s right there.

Same place on a Touring (although I've not had cause to change it).

It's a good idea to change the fuel filter periodically too - the one on my E39 sprang a leak and according to the stamp hadn't been changed for 10 years.

@HardBall66 I’ve actually got one I’ve been meaning to install

Good advice this. When I changed mine this year, it was still the original from 2001!  230k km later...
