Quite a few people selling these on eBay. It's just unfortunate you have to wait a while for delivery.

would that fit, it is a different shape?.

3disco has contacted me, see social forum and very generously offered me a pump if I need it.

My plans keep getting messed with but I hope to test my pump tomorrow.

aaaaghhh must read posts in order, thank you Mike good lead

Not sure what you mean, it's identical to the one fastened to the side of your FBH apart from the plastic inlet pipe, which you can swap with your own pump if you so wish.

the pump in the photos I have posted are this pump!

Correct Ian.

For starters, the problem is not the water pump. 1/It has passed the start up test and running, otherwise it would shut down after a few seconds. 2/The FBH is not firing up for its poor performance to cause shutdown.

Water pump interruption failure to start
After the air fan is started for about 3 seconds, the PCB tests the water pump current draw, if the PCB detects a problem with the water pump current draw, it switches off the FBH immediately, then purges. Regardless of the water pump looking like it is pumping enough water when 12v is applied.

The PCB however can be misled, causing it to shutdown.

A FBH can fire up, then go into overheat shutdown. Either the water pump on board PCB has a fault, and is sending false information to the FBH PCB. Or the Water pump is drawing the correct amount of current but the impeller is seized or sluggish.

Water pump interruption failure to start with a good water pump
The PCB fails to send current test signal to the water pump.

After around 2 minutes, the glow plug is switched off, and the PCB requests flame condition, if the PCB does not get the reply within the software parameters, the PCB shuts down the FBH, and purges the combustion chamber.

Resistance testing is a good guideline, the only way I would pay for a used glow plug is after I see it fire up a FBH.

Using a known working PCB to test run a FBH will do diddly to the PCB, it will just record the faults.

MO. Try both plugs in a FBH using the known working PCB, (If you are certain it has not developed a fault). if it does not fire up, Voila.

Nice one Mr D I knew you or rob would have the answers for the OP and it did not take long

Sorry but you have confused me. This is where I'm confused

could you tell me probably again how many ohms the glow plug should be?
I will test the one on this fbh, the one on my saloon and a 2nd hand spare.
see what they all read

At 18°C - 30°C = 0.245Ω - 0.345Ω or 0.4Ω.

What if they all read 0.5XXX0.6XXXΩ or 0,7XXXΩ Will they work, probably, I have known them work at this resistance.

Unless the air fan starts, then stops after around 3 seconds, then purges, it is NOT the water pump.

If the PCB starts the water pump, the water pump is NOT the cause of the start up interruption.
