haha, yeah... The multimeter is useful for you not to throw useless parts at an ailing bike. Read the starting issues page http://k-bike-knowledge.000webhostapp.com/electrical/EFI/bike-wont-start-EN.htm It has got all the values, you need and all the places, you should measure at. For example if the air temp sensor is bad, or the cables from it are bad, the computer could be thinking, it is -200C outside and will overfuel mightily...
Thank You. Hopefully I can make some sense out of it before I throw the multimeter at the bike, let alone any parts!

A picture is worth a thousand words.

After thousands of helpful words and an untold number of requests for photos of your bike,  you finally post photos of your workshop manual, multi meter and your concrete floor.

That's not only time wasting, it's insulting. Don't think people have gone on holiday.

Ok. Had the tank off today. I was told on here by someone, can’t remeber who, that when the fuel pump comes on, it pumps the fuel out of the tank, to the rail to each injector, then excess goes back up to the tank via the front pipe on the rail, closest to the front of the bike.(the one,ringed). Only, I gentle put a thin screwdriver up the ‘inlet’, but it would only go in about an inch or so, then stopped as though it was a ‘dead end’, so to speak. Is that right? It seems to me that the fuel that passes the injectors just goes up the pipe to the tank, and then stops. Is that how the pressure for the injectors are formed?

Also, had the injectors out today to make sure they were firing off right. No.3 never worlked, swapped 3 with 2,and it worked, so connection.Gave it a clean and a wiggle, all three worked. Put em all back in.

Bought some dedicated maf cleaner and done that today, too. First pic dosnt do it justice, but to me, the second pic, it does look a bit cleaner. That might help(?).

It is difficult to see on your photo, I think you have connected the fuel hoses to the tank the wrong way around.

No - the front hose on the rail is not the return, it is the supply.

Swap the hoses on the tank,  you should then be able to run your finger along the hose from the rear barb of the tank to the front barb of the rail.

I think your bike will then run.

Also if your tank is off the bike,  attach a hose to the front barb,  you should then be able to blow air into the tank, if not then the valve in the tank is blocked, if so it is an easy matter to clean out.

the pic is taken from the right hand side of the bike, but looking undernearth, so in the pic, the right barb, is the front barn.

yes. By hoses are the right way around, exactly like this, from the link you sent me (minus the manometer).The bike did run before. I could put a vid up with it running, but I don’t know how.

Looking from the left side of the tank,  does the hose at the rear barb of the tank join with the front barb of the rail? That is the right hand barb on the tank with the left hand barb on the fuel rail.

The return hose has a 90 degree bend just before joining the tank at the front barb. Your photo shows a bend on the rear barb which makes me think you have the hoses at the tank the wrong way around.

Actually after a second look it may be OK as the tank is tilted more than I thought.

Can you blow air into the tank?  use a dry hose to the front barb.

Hers a photo of the inside of the tank. As you can clearly see, the front barn is naturally blanked off from the bmw factory.So no, you can’t blow air into the tank, and it’s NOT an outlet. Like I said...the bike DID run, but roughly.

It looks like it is blocked.

If fuel can't return, and you say you can't blow air into the tank, it is blocked, therefore fuel is not returning to the tank. Therefore the pressure regulator can't work.

Therefore you have about 60 PSI instead of it being reduced to 30 by the regulator, causing overfueling.

I know this is hard to believe but fuel must return to the tank.

You need to fix this.

And here is a pic of a spare tank which came with the bike, I think it may be a k100, as the fittings on the rear are different. But even so, the inside of this one is blanked off,too...

Actually it does look good inside. My spare bike looked different inside but my main bike looks like yours.

If you can't blow air in, the check valve is blocked. Use a spanner to remove it, clean it.

It might look blanked,  but it. is not.  Do not poke straight sharp objects in the pipes,  as you can see,  there are bends in the sensitive aluminium pipes.  Use a piece of stiff wire,  ideally with the outer cover still on,  or even better is grass trimmer nylon wire.  I am sure you have kilometres of the stuff being in landscaping business...
