Fuel pump

Post by Ray »

It seems that my fuel pump is not working. Wont start and no initial noise from pump on ignition switch on. I still have to check relays etc and lpg wiring. Are JP pumps any good as bosch are £95 or more. Never had any starting problems before even after the van standing for long periods between use.

Evening Ray, 
I would be learning towards a dirty corroded connection before dismissing the pump.
it should still start on lpg tho , unless yours was set up to always start on petrol first before switching over ?

JP stuff is all far east made, its a fact of life. All Bosch are generic design regardless of application or vehicle brand, they all pump the same so just find the best price.

Yes, mine was set up to start on petrol and then switch to lpg. In fact last week it did start I think on lpg because I let it turn over for so long. The pump is in such difficult place to change especially for an old geezer, still it will get done!

I would check there's power going to the pump first. This can be done starting at the pump, then if no good the two pin connector at the bulkhead, and finally at the relay in the box above the coil. Also check any fuel pump/injector switch off relay used by the LPG system.

Tried all the ways suggested, wasn't electric supply or pump. Got a mobile mechanic to look at it and found blocked pipe post filter. Anyway now new pump and filter and familiar with total gas and petrol circuits and back on the road. The filter is in the most inaccessible place, glad I didn't do it.

Yeah, they're not much fun to do and worse if its a retrofit! Glad you got it sorted though :ok
