can someone tell me if there is a bleed screw on the fuel pump? if so which one is it?

there is on the side of the pump facing the radiator (8mm spanner) and one on the back below the injector pipes (about 10 or 11mm spanner). thinking it will be one of these two but dont wanna go undoing random bolts on the fuel pump!!

its an r reg van non turbo if that helps

cheers

 

iirc there is a black button type plunger to bleed the fuel. Its on the side of the engine on top of the fuel filter.

 

done that all bleed & its working, i understand the primers can be a problem but the primer is getting hard after a few pumps and i pulled the supply pipe of the back of the pump and there was loads of pressure, cracked the injectors off but there doesn't seem to be any fuel coming up. dont want to crank it over too much if the pump is dry.

 

could be the solenoid?? in the fuel pump it may not be lifting up that could be causing no fuel to the injectors but you would still get fuel to the filter.

 

well i am assuming it wont start?

 

got fuel to the filter, got plenty of fuel to the pump just nothing after. was running fine, changed the filter now it wont start. will cranking it over do any damage to the pump?? if not i will just persevere with it.

cheers

 

If the fuel is getting to the pump but not coming out then the problem is there somewhere check the wire to the solenoid sound like its not opening.

 

can get it to run for about 5 seconds if i build the pressure right up in the line between the primer and fuel pump, soon as the pressure is gone it cuts out. any ideas?

where is the stop solenoid mounted?
have looked on the pump and cannot see it, there are some wires going behind the cover on the back of the pump but think they may be for the immobiliser.

also, how much fuel is meant to come from the hand primer on each pump? im getting about a teaspoon full which is coming through quite frothy, this leads me to think this is knackered.

just been to halfords to see if they keep them in their imense parts stock, after clarifying that i didn't want a 'ham primer','grey primer' or a syphon pump, being told that they didn't exist and giving 3 of there well trained staff a lesson on how a diesel engine works i gave up.

gonna get a new hand primer on monday and have another go. fingers crossed

 

sounds like primer b warned 95 odd quid new did u take off return pipe with ignition on and pump the primer until diesel came out the return

 

thanks, thats what i think it is.

used to work at a ford dealer, just been quoted Ł35 for a ford one. going to get one at lunchtime.

 

fixed it.

if anyones interested, it was the hand primer. the old one was pumping fuel but only about a quarter of what the new one does, and it looked like it was drawing in air. still took 4 or 5 attempts but a few squirts of brake cleaner down the inlet helped her cough back into life.
