cheers jb  p.m my your address mate and post code will saturday be ok ?

Can you smell fuel when trying to restart ?

Could be:
Leaking injectors - whip them out and put in jars to test.
WUR giving an incorrect control pressure for hot start, hence a crap mixture - measure it !!
Accumulator no holding system pressure, it should hold of 25mins before pressure decay starts - measure it !!
Check valve on the end of the main pump partially blocked, which means fuel will leak back - take is out and clean it.
Fuel pump really overheating, which can lead to fuse box corrosion - look for heat damage.

when go to resatart there is no power going to the starter until i run a wire from the battery this wire and then it will start .i have always smelt petrol ever since had car ?

Ade it's a carb model.
I had this problem and it was the starter motor.
The heat from the exhaust manifold tends todo em in.
We had cured it for a while as there is a wire with a connector that goes funny.

I think from memory Dek has had new starter, new ingnition switch etc. It's baffled us for a good while.
It will start by hot wiring it straight from the battery so it kind of points to ignition side, probably heat related as when hot a connection expands so breaks the circuit, when cold the connection is remade.

Hope it gets sorted Dek.

Is yours a auto box I. Can start mine when its hot lol it looks like I'm nicking it . I think its to do with the starter motor been under the manifold or wiring

I had a hot start problem with my Rivage when I bought her it was the non return valve in the fuel pump replacement of the fuel pump cured it never happened since!! Used to drive me insane!! Hope this might help

There are differences between GTI and Carboureted models though.

AmaZak yours a GTI or carb model.

Mine is a Gti, however my friend has convinced me to ditch the K-Jet injection completely and fit a golf mk3 setup with standalone management so I have bought mk3 engine and he is going to fit it for me, might get a few engine mods too  :twisted:

Battery was faulty, fitted new battery all good now.
