When its hot ....turn it off wait 5 mins ...very hard to start again seems to have lost quite alot of its bottom end power too
Any ideas anyone :-/ :-/
-
The hard to start when hot is a common problem and there's a cheap fix on Ebay which works by fooling the glow plugs into thinking the engine is cold and heats them up aiding start up.

Yep just been reading the previous posts (should have looked there 1st) its done a steep decline past 2 days its gettin a bit embarising now ...had the same prolem on a Rover 600 Td never did get to the bottom of it similar VE 37 bosh pump... i have alwas ran my cars on Bio diesel without any problems apart from this hot starting milarky the lack of balls at low revs is a bit concerning to ...it idles perfectly
-
Have you checked the small pipe that runs from the underside of the inlet manifold to the boost sensor, make sure its not blocked
-
No Pete i havent whats that do ?
-
sorry arent i thick somtimes ?....it goes to the Boost sensor ......its ovbious what it does
-
I have the same problem with Syd, I have go the hot fix kit from Ebay but have not fitted it yet as the alternator has just gone. I always carry bottles of cold water to pour on the pump just in case and this has got me out of some awkward situations. Once its hot it would take a good 20 seconds to turn over and each time I think the battery is going to die :o I got a new battery and made a huge difference until the alternator went last week :(
-
The "Cold" water trick seems a good idea ....i am suessing the pump has some sort of tempreture sensor in it and is letting little fuel in the ebay box would hold the glow plug relay closed for a little while whilst enriching the / letting more fuel through hence 1 wire from it goes to the ecu ?....ill see how it is in the morning as i said earlier its got alot worse today spk tomoz of to bed :y
-
I've read the water trick is to do with the pump expanding when hot so its not pumping as much, pour cold water on it and it contracts, but don't know if thats right ;)
-
Not sure why it works but it does :y :y Im just impressed I know my way around the engine let alone understand how it works :D :D :D :D

There's a fuel temperature sensor within the injection pump.
I'm pretty sure that it's non-serviceable, Omegatoy can probably confirm.
First, when the hot start problem occurs, try pouring a jug of cold water over it. If it fires up, then this sensor is your problem.
Next, what's your battery condition?
I cured mine, (and one or two others), by fitting a correct model-specific one, as I had a hot start problem even after fitting a new injection pump. It's run with no bother since.

My TD starts instantly from cold, should do I have had new glow-plugs only around 15000 miles ago.
I have got a slight hot starting problem, in my case it might just be the battery. They don't last forever and I reckon it's still on the original factory fitted one, which is 9 years old, so not bad. I think it's about time I changed it before winter, or it let's me down.

I've just fitted the Vauxhall 95amp one to mine, its large but does fit and its the same price as the 85amp one ;)

I see you're becoming a TD expert now Pete, nothing to do with the work you did on mine is it? ::) And I see you also drive one too.

Don't know about that Mick, i'm having trouble getting the thing running properly ;D

first off i have never changed one as never needed to!! however the cold water trick is just a way to test the fuel temp sensor is working or not!! i never intended for people to carry bottles of cold water around ;D
however the fuel temp sensor is apparently changeable while the pump is on the car, and not suposed to be too bad a job although fiddly!! for thse that have the rr download if you go to the pump it shows the temp sensor location, and any good bosch agent should be able to supply the sensor :y

a friend has just told me her dad used to keep a cool box and frozen peas to cool down their pump ;D ;D ;D ;D ;D ;D at least my water bottles come in handy when the dogs want a drink in the car :y

Hey thanks for all the replies guys Very helpfull
ive been looking on the net all day for the "root" cause of this problem all day i appriciate the ebay box would work / does work but it does seem to me the fault is caused by the Fuel tempreture sensor in the pump as the Very tallented "OT" says
its a common problen with all Bosch VP type pumps

Its all done ;D ;D ;D

thanks for all the help & advice given
