Eberspacher / Webasto 12v Diesel Fuel Pump

i dont get the clicking sound from the pump any more and its not sending the fuel to the heater but there is a power supply there just under 10v is that enough to power the pump when i put it on a battery it only pumps once does this mean the pump is dead

I don't think it's a pump that has a rotary shaft, I think it's a solenoid type pump which is why it pulses(or clicks) when it's working.

Basically the voltage is pulsed(switched on and off) so putting a vlotage on it from a battery would give you one pulse so to speak. I think your problem lies elsewhere - usually the glow plug I'm afraid.

tried the glow plug and its fine i have a constant feed to the pump does any no if theres is the same or does it pulse

does any1 no if you can put a differnt pump on as from what i can make out the aux heater unit has a level for the fuel so it should cut the power when the fuel gets the the right level

you were right it should be pulsed any1 no where i can go from here or where i should look next
