Sup people,

Had an issue with my mom's Mini this morning (Friday). I turn the key and the car cranks, but just does not fire. I pulled the code a little while ago and got only one: P0326 which is the knock sensor.

A little back story:
I poured gas into the tank Wednesday night from a gerry-can that I filled on Monday with pump 93. It was 5.5 gallons. Along with that I added one of bottle of those fuel injector cleaners. (The reason for the 5.5gal gerry-can is I filled it with lower $ gas from NJ versus NY). Currently have ~95,000 miles. I only use 93 in the car.

The car was driven yesterday (Thursday) with no problem. Only this morning it did not start. I have the battery disconnected for now to clear out the ECU.

What do you think could be preventing the motor to start? Would it be as simple as a bad knock sensor or something more serious?

Thanks in advance!

 

Also to add to that, my exhaust has recently started to rattle.

I found this thread that might be a clue to P0326:

No idea why it won't start though...

 

Not getting spark at the plugs. If I have the wires+plugs next to each other, you can see the spark jump from the base of one plug to the other. I'm hoping this rules out the ignition coil and they're all just bad plugs, but I'll get it tested anyway.

Did these cars come with 4 pole spark plugs from factory? They say Bosch BMW 105 R3 on them with FGR7DQP GERMANY on the metal.

 

Nvm the above. I am getting spark at the plugs. The BMW plugs seemed to be put in by the dealer.

Now onto the bad news. I think my fuel pump is dead. Had a friend help and point out there was no pressure when he squeezed the fuel line. What I thought was the fuel pump priming was the electric throttle just buzzing. The fuel fuse is good and the fuel pump relay clicks, swapped it to make sure and still nothing coming out of the fuel line. I don't hear buzzing from under the rear seat so that means I might be out of luck. A clogged fuel filter would at least pass some fuel. I get nothing out of the line.

 

Changed the pump with one I bought at a junkyard.
Fixed.
Took me 1.5 hours. Most of the time was wasted swapping the brown nozzle hose. The junkyard people cut it, so I had to swap mine on. Didn't reuse that stock metal clip, just grabbed a metal hose clamp and screwed it down.
So far so good.

 

Glad you solved the problem. Thanks for all the updates along the way.

 

Thanks. Drove it in this morning. Runs alright.
