Sometimes it will sometimes it wont

Hughie · 2017-05-26 18:36:30

Hi my little dispatch 1.9d has an issue and its driving me crackers, starts first time of a morning no problem at all and also 9 times out of 10 when its been warmed up.
?
Then every now and then if I have a short stop after a drive she will not start as if its fuel starvation,(and I have to wait maybe 20 mins or more before she does start) a mate of mine mentioned the stop solenoid could this be the problem and if so where on the fuel pump is it located ?

Any help or advice would be appreciated...

Cheers and Beers

Hughie

Is it dead when it wont start as in no dash lights or anything like a shit earth? Or does it only do this if you have a hot van and stop to nip in for a paper and the bugger wont start when hot. Is the engine/starter still spinning on the occasions when it wont start. Have you tried the prime to see if this helps on the non start occasions. An odd one indeed but more info needed.

Hi Casper, aye its if I nipped in for a paper and then it wont start...it turns over ok and it is as if its fuel starvation.
Tried to prime it yesterday when it played up and it made no difference..left it to cool off for half hour or so and it fired up.
The stop solenoid has been mentioned but apparently its hidden away on the fuel pump and you need to remove some alloy to get at it ?

Cheers

Thanks for that mate

Did you ever get to the bottom of this?
Mine refused to start the other morning - no smoke and not even a kick. I reseated any connectors I could see around the fuel filter area and primed until hard. One last go and it started up.
It may have been coincidence but the evening before I drove through torrential rain with flash flooding. There was water in the engine bay - the felt above the aux belt area was damp.

I am going to change the stop solenoid but haven't had the chance with work.

After a few taps with a mallet on the solenoid housing and the van starts up.
I wonder if a dousing of wd40 would get anywhere near it?

From what I understand the solenoid plunger sits in diesel. I'm thinking that dodgy fuel (we are traveling in the Balkans at the moment) may be a factor, though I did change the fuel filter before we left. I wonder if some additive for cleaning injectors might help?

A mechanic friend of mine thinks its the starter motor getting hot, expanding and tightening up.....sort of make sense in that give it 15/20 mins and she starts up again...and while it wont start it seems a bit slower turning over.

He could be onto something Hughie as i had that exact problem in the 80's with a NIssan Stanza. Replaced starter problem went.

I think I have a different problem. The van will start ok if it has been stopped for a few minutes. Any more than maybe 30 mins and its a problem, which is getting worse.
Today I had a listen at the fuel pump, and I'm getting a buzzing noise rather than a solid click. The buzzing only lasts while the glow plugs are on.
This noise has always been there and I just assumed that it was to do with the preheat timer.
Has anyone else heard this when starting?

I've notice my VW taking longer to fire up of late if left to sit for a bit..... dropped it off it at garage for couple days ..... Turns out Ive got a small drip/diesel leak somewhere about the pump and it's taking that extra second or two for the fuel to get pumped through .....
Seams a bit of a controversial subject as my Vee Dub's 22years old... So is it just age that's caught up with pump or is it the Ultra Low Sulpher Diesel that we're now subjected too........
Been told put in Mineral low ash two stroke oil or type F automatic trans fluid, even power steering stop leak in the tank to try soften up the seals in pump Etc

I did many moons ago put 2t in diesel tank of a Corsa when scaremongering about city diesel when it first came along, about lack of lubrication for diesel pump and it was all I could get at time when i was living in south London

Don't know what to think VW has only 110,000 mls on it SWMBO's 306 has over 200, 000 mls and doesn't leak (both have Bosch pumps)
