of how much diesel is in tank. stopped working today. added 20 litres and no difference. done a search and its probably the sender unit/fuel pump. but not conclusive.
any one got some other ideas i might try.

when it happens in my transit (when i fill up from very empty) I go find a few speed humps and enthusiastically tackle them, stops whatever sticking every time.... worth a go before you start taking things apart?

its not a difficult job to remove rear plastic strip and pull back carpet to remove inspection plate and check sender/pump unit ,once out of tank (allow to drain before pulling out completely )you can check power to sender and if moving float arm makes a difference

just thought maybe the float arm in the tank could be stuck, possibly worth a go.

if youve filled it up from very low your float could be stuck may just be able to fix it by lifting the pump out the tank than putting it back in again.

finally fixed it today. basically put an avo on ohms across sender pins on pump and did not get a reading. next step was to remove pump hopeing to see that one of the blue wires had become detatched. but everything looked fine, bollox, a new pump i feared.
after more avo readings were taken, i noticed that one of the solder joints down by the sender arm was not making contact with the printed circuit board. with a magnifying glass i could see a small break in the circuit. this was easily fixed by resoldering the joint with a bigger blob of solder. all working fine now
