I'll chime in. I have a daily driver SPI. I found the in line fuses behind the air cleaner can be problematic. One of the 3 brown wires (ground) is not getting power & can make the mini inoperable. Sometimes it is the glass fuse. Take a multi meter and see if you have continuity in the glass fuse and see if the ends are secure. If all fuses are ok you will have to check the fuse holder. Take pins and stab into the fuse hold at the wire ends to see if you have continuity. Again it's only the brown wires.

I can offer almost no suggestions but for clarity I have a question. Different parts of the world use the term "bump start" differently. In the U.S. a bump start typically means switching on the ignition, selecting second gear, pushing down the clutch pedal, and having someone else push the the car up to maybe 5 MPH before you release the clutch pedal to get the engine spinning.
Is that what you mean?

Oftentimes on the injected Minis, a failure like this is due to the so-called engine relay module on the right side of the Mini (facing forward) next to the firewall. It's a black box with a large multi-pin connector.
If the Mini mysteriously comes to life tomorrow or later, then I'd bet 5-1 odds that's the problem. If so, you'll need a replacement module. It may be possible to open up the module and fix it - many times the failures are due to carbon arcing and other contaminants, and possibly a bit of re-soldering work. But better to get a new module to be sure and keep the old as a backup.
Part number is YWB100970 for MPi cars, it's different than the part number for the SPi injection models.

I jumped in my MPI mini this morning and everything seemed fine, it started up okay and ran perfectly. When I got back from the shop it decided not to start, however it has power. When I turn on the ignition the fuel pump engages, all of the electrics turn on and the immobiliser light goes out when I press the button but nothing happens when I turn the key. I have tried pressing the inertia switch and still nothing. Any ideas??
