Known problems so far:

• Fuel gauge not registering: Half a tank of new premium fuel and a new fuel pump are in place, but the MINI doesn't seem to realize it has fuel in it, with a flat fuel gauge. Attempts to reset the ECU ran into a problem when using the amazing guide by shorty_du_op. Specifically I get stuck at step #5 when I get into the system but am supposed to "scroll through" to choose the next option, but how do you scroll with just one button to push? When I push the button at that step it seems to revert back to simple odometer function.
• No spark in 3 out of 4 plugs: Spraying starter fluid into the manifold had me hearing the engine trying to turn over. suggesting a fuel problem, however after checking spark plugs it seems like the engine was only working with one functioning spark plug.
• The car sat for about a 12 months with the stick in neutral and I cannot shift it into any gear position. Seems as though the linkage is frozen.
• MORE SOON

Additional items on the agenda:

• All four rotors will be replaced
• New wiper blades
• The center brake light lens is missing with exposed LEDs
• The rear tail lights stay on after turning off the car with no obvious reason why
• New oil and filter
• New air intake filter
• New cabin air filter
• New tires: the car was purchased with 215/45/R17 tires on it, but every source I can find suggests the stock tire is 205/45/R17. Unknown if the previous owner was simply trying to get a larger contact patch on the ground, but I will go back to recommended tires.

 

You've got your work cut out for you but as you tick the boxes on your to-do list it is quite rewarding. Good luck.

 

Just a couple of other things to consider.

- GEN 1 Mini's typically need thermostat's replaced more often than other cars. You should replace the entire housing. Also check the reservoir for evidence of a leak.
- Consider doing a compression test on a warm engine. If your test is not consistent across cylinder's try adding a teaspoon of oil and perform a wet test for further diagnostics.

Have fun and keep posting updates. There are a lot of folks here who have been where you are who can and usually will offer pointers.

 

Sounds like a bunch of little things. Good luck and hope we can help with any parts you need.
