[Fuel pump electrics]

Hi All

Success!  Spurred on by comments here I whacked the pump a bit harder this morning with the rubber handle of a screwdriver and it came back to life - miracle!   Bruce from the Chiltern TR Group who has a 40 year old yellow TR6 he has had from new popped round to help and we went for a lovely spin. All good, fantastic to get the 5 back on the road.   Thank you all for your patient guidance.

Thanks guys. I have checked the spade connector.  It is connected to the car body - not sure what else to check there.  It is a TR5 and all very original except for usual switch to Bosch pump so I don’t believe inertia switch (not sure what this would look like if it did have one).  I have called out the A.A. and will ask the mechanic to check the voltage at the pump and also the ignition lock - can you suggest how we check the ignition lock current functioning? 

Thanks once more for your patient guidance

Ah...has someone come up with a better version of the Lucas?  I saw something about a Mike Pumford Lucas system - nice to be more original if works!

Thank you.  It was fitted by T& M Classics, Thame, Oxfordshire (I don’t believe they are around anymore but had a good reputation) and I believe is in the original position where the Lucas pump was located...

Here are photos of pump and filter

...very strange that was working the day before I charged the battery...perhaps it picked up a bit of sediment...do I now need to replace the pump and filter for good measure?

...we also tried boosting the electricity through the wiring to give it a bit more oomph...nothing

Have tried tapping the pump with a rubber hammer

AA man here. We can measure 12.15 volts at the pump with ignition on first position.  Perhaps the pump has suddenly “gone”. Would have thought would hear some effort or noise from the pump. Anything else we can try while he is here?  Perhaps I can ring you quickly?

Hi

I tried to start my TR5 which had been stood for a while and found whilst the battery was allowing the Bosch fuel pump to whir when I turned the key there wasn't enough juice in the battery to start the car - no surprises there.  However having removed the battery, charged it up etc I then turned the key to find that the fuel pump is silent and clearly not working so the starter motor is clicking away with no fuel coming through.  I have checked the fuses, I have checked all the wires connecting to the fuel pump but can't find any obvious issues.  Seems very strange when all I have done is remove and replace the battery after charging it up.  Any thoughts/assistance?

Thanks a lot
