Van just cut out

[albertramsbottom]

Hi

Going for a drive yesterday and the van just cut out. I have just had my carbs refurbished and it has been running like a dream.

Does anyone have any advice for the diagnostics. The van sounds like it is trying to fire so I thought that I would check for sparks. If I have them then I should check for fuel. But i dont know how to take the fuel filter off. Do you have to clamp the fuel lines either side of the fuel filter?

Cheers guys and girlies

i had the same problem with my 1.9dg, it ended up being a fuse, it was the last 16 amp on the right. (dunno what it was for tho) maybe fuel pump ???

My 1985 1.9 DG has a mechanical fuel pump. My van just cut out also, I checked the sparks were ok and then checked the fuel pump. I disconnected the pipe to the carb and found there was no fuel coming through on cranking the engine. I removed the pump and found it worked OK on the bench. I fitted it back to the motor but ran a feed pipe to a bottle of petrol by the engine, it worked a treat. On reconnecting the fuel line the van ran for quite a while but then started misfiring. I will try it again tomorrow to see if it starts OK. It seems like the pump can't lift the fuel from the tank properly.

its quite common for the mechanical pumps to fail in this way, sometimes it is the diaphram in the pump, with it appearing to work ok but cant manage to blled the fuel out from the tank, and sometimes it can be the push rod that works the pump being worn, just a fraction, stopping the pump doing a full sized pump making it weak , although my first stop would be the fuel filter.(and you should onlyhave one, by the tank.)

Thanks for information guys, im not sure whether i have a mechanical fuel pump or not but i would have thought so

How does one go about taking the fuel filter off becuase I couldnt find anything on the wiki?

Right I have just been to my van and I have a couple of questions if one or more of your have five minutes.

Firstly, I have taken the airfilter off so I can peer in to my lovely shiney carbs after a refrub with gassure. When I opperate the throttle from the balance bar I can see fuel being squirted into both carbs.

Now does this mean that it isnt a fuel issue?

Or is this a mechanical action that pulls the fuel in to the carbs? and therefore it still could be a fuel pump, filter issue. I just would have thought that it would fire and then stop if that was the case. But it wont fire.

My other question is that I am shortly going to see if there is sparks and I was wondering how I can test to see if the coil is working. Can I pul the miidle high voltage lead off the miidle of the dizzy and test this the same way as the spark plugs or is this unsafe?


Thanks for all your help

take a ht lead off a spark plug hold it in insulated plyers and hold near the block of the motor. get someone to turn the motor over, you should see spark. if you cant see anything fit a plug into the end and repeat. if you have spark then the coil is ok. coils tend to fail when hot.

if you have spark

there will be a idle stabilisation box in the engine bay on the far right rear as you look at the motor. there will be two plugs coming out of it , remove em and join together. see if that helps any.

Yippeee

It was the coil. Changed it for an old one that was taken off before, when it turned out to be the dizzy. I always knew that the old one was OK. Strange though the new coil was only 4 months old

Thanks guys - Its alive!!!!
