Probably electrical as above, but possibly the transfer pump inside the tank. It pumps fuel from one side of the tank ‘over the hump’ in the middle to the other side. If it’s faulty, you have no fuel pumping from the higher side to the lower side.

Test it, but indeed sound like you need to treat it to a shiny new battery

Yes 🤨

Fancy posting questions in a thread that everyone ignores… 🙄

How long is a piece of string? You’re looking for an alternative to a disco, but you rarely tow and rarely go off-road? So you could, in fact, have any car you like or can afford.

So what is a groove supposed to do, as a benefit, that holes do not?

I’m no great expert on brakes (can you tell?) But - I can see the potential benefit of holes in the discs aiding cooling. Beyond that, and unless you’re into super-speeds and heavy, prolonged braking, I don’t see the benefit from grooved discs???

Put a bit of grease on the discs, that’ll stop it… NO DON’T !!! I’m with your ‘glazed disc’ explanation. Don’t you have a couple of spares in your stash that you switch briefly, to rule in/out?

I think removal and cleaning of injectors would be a reasonable (and cost effective) stage one to try and address the problem, even if it requires buying a cheap sonic cleaner. If that didn’t work, I’d go to stage two and buy a known ‘good’ injector from someone (here) and replace each with it...

Wow. A freezer in the Impreza? That’s some optional extra there!

I spent all day yesterday ignoring this thread

Can you bend that low to get in…?

Check your camshaft position sensor - if this is faulty it will cause starting issues. (It won’t necessarily give an engine fault code.)

Ok chaps, update on @ChuggyFreelander ’s car… Main issues for MOT are excessive smoking and handbrake. My advice was to sort the smoking first, if dealt with, then replace the rear brakes. Seems to be an injector issue going on as the balancing range is between -5.4 through to 6.2, which seems...

@ChuggyFreelander Off-topic, but as promised; PB blaster is my first go-to for releasing rusty nuts and bolts. Soaking time is your friend here. Owatrol Polytrol is brilliant for restoring your black trims on the car.
