Purging Fuel system Disco TD5

[Discotel]

Hi peeps,

How do you purge the fuel system on the above vehicle, I have just fitted a new fuel pump and tried the old 3 minutes with the ignition lights on, then crank it, wait 15 seconds and repeat...It wont fire.....Anything else I can try before it goes to the garage or up in flames ...I knew there was a reason I went of Landys..Pain in the ass.

Cheers, Terry

turn the ignition on,then imediatly press the acelarator pedel 6 times,the engine light will flash,and then the pump will start to purge,but if you've tried to start it,you've pump more air in,so do this procedure twice,hope this helps mate,jim :D

Cheers Jim, Will give it a try in a mo, if it works mate I owe you a beer... :lol:...I really hope it does work as I am regretting buying the bloody thing already...Only had it 2 weeks, its been dead for one...

Cheers, Terry

no worries mate,i just read the first post you put on,looks like other people had said how to purge the system,but it is the way i said,cause i had to ring hunters for this procedure,as i done the block that i was talking about in your first post,about 2 weeks ago,lol, i know what you mean,they're a lovely truck,but costly when they go wrong,and you may may be able to help me in the future,lol.

Can you believe it, Ive now killed the battery trying to start it...I have had it now...Im gonna burn the bloody thing...Was in the process of trying your method Jim and the battery has died...Nice....

Quickly, After I have pumped the pedal 6 times, the engine light did come on and flash, when do I try and start the car, while it is flashing or once it has stopped...?

[JIMBOBLY]

sorry mate,i forgot that bit, i do appologise,lol,when the light starts flashing,the pump should start pumping,it will last about 5 mins,let it run till the light stops flashing,like i said,do it twice mate,just to be safe

[Discotel]

Ok mate, gonna let the battery charge for a bit, teh nput the boost pack on aswell just to make sure, I really hope it works, could it be anything else stopping it running...Like I said the diesel was low but I had only done around 10miles with the light on..the pump starting making a loud noise then the car died...I called the AA out and he thought it was the fuel pump, as did I, so I fitted a new one and still wont start...The new pump is making the same noise but for a lot shorter period...I take it this is the air in the system...Correct..?

while its charging i thnk if i were you i would some how get a few gallons of diesel i changed my fuel filter and what a night mare it were to blead just as the battery were about to give in it started

[JIMBOBLY]

yeah,the pump will make different noises when there is air in the system,when its bleed up,you can hardly hear it,the reason the pump gets loud like that,is because it starts to run dry,like a power steering pump,they get louder when the fluid level is down,simlar kind of thing,and by the way,when youY do the procedure we,ve been talking about,dont turn the engine over whi;le its going through its cycle,as it will cancel it out,and put more air in the system

[Discotel]

Hi again, it still wont bloody start, How about I try and take off the fuel lines from the engine and see if there is fuel coming in...Where are they located please....Or shall I just keep doing the procedure you suggested...?.....

[Discotel]

IT LIVES...Changed the crank sensor and purged the fuel system....She fired up and runs a treat.

cheers to all for there input.
