I've had a horrible thought. Have you ever removed, disconnected or otherwise distrubed the pipes on the fuel tank sender/pump unit flange? These are the pipes i mean :
One is temporarily removed in the photo and the other one on the stub immediately below the exposed stub are the two i'm worried about. Have you ever touched them?

You need to read this and understand at least the system-level operation of the K fuel system. It will be worth your while - its now almost 10 months since your car stopped, and throwing bits at it and making uninformed guesses has not resulted in any forward motion. Its now time to admit that well-intended ignorance is still ignorance. Also, you need some test equipment. A DVM (even a cheap one will be ok) and, ideally, a fuel pressure gauge will greatly increase your chance of success. Trying to fix the problem without these is like trying to find a black cat in a coal mine without a flashlight. |

by my count, this is pump #3.
I don't think its the pump. The bloody car hasn't moved, the pump has shifted less than a litre of fuel in this time. Even run dry - completely dry - in that amount of time its not going to do huge damage. So the problem here is not likely to be the pump, especially given that it appears that only a day or so ago it produced enough flow and pressure to at least start the vehicle. The problem here is we are playing blind man's buff. |

Click the "Share" icon : and a list of links will appear, each with a blue button at the end. Choose the one that says "Hotlink for forums" and click the blue button at the end of the line. It will briefly change to "Copied". Now switch tabs back to the post you're doing, click on the cursor positon, then right click your mouse, when the options come up on the screen, click "Paste" then hit return on the keyboard twice, first gets you onto the next line, next one inserts a blank line to make it easier to read the next line of text. The rest you'll have to find through trial and error and playing but that will get you started.

fuel pump
yes i think the pump wires are the right way around .the pink is + the black is-.but the connections are slightly diff due to the sizes so its not possible the little 8m nut is not going to go on the 9m nut

Are you talking about the in-tank pump all the time? If so, it sounds as if the underbody pump isn't doing what it should.
