Thanks for the suggestions.

I have fashioned a relay bypass and have even tried wiring pump direct from switched live and no difference.

Came across a thread a Golf Mk1 website in which someone said he had problems with a pattern injection tank. It appears the car would stop after a few miles ...

That's a good point. Someone has suggested a rolling road, none near to me though.

Yes throttle opens fully. Injectors are new and flow the same amount in a given time.

Had a look at the crank breather valve. Never given it much though but it is a source of unmetered air, seems to be standard ...

Thanks for the reply.

Hi, yes compression test has been carried out - they were in the range of 165-175,

To be honest I don't know if they were tested under load (they were done with a diagnostic scope). They said all the results were very even and gave me a print out which refers to U-secondary ...

Hello again, still trying to get the Mk1 to run properly !

Had the Metering Head refurbished by KMI. Came back looking like new. Car was slightly better but still was hesitation and lack of top end power. So new fuel injectors, seals and accumulator. Checked fuel supply on return again and it was ...

Thanks GT II, that's interesting. I guess I should have explained why I asked about this - well I have restored the car over a few years and can't get it to run properly. I was convinced it was the fuel system and by now have renewed most parts - filler neck, tank, pump, filter, metering head, WUR ...

Hi, I have a metal shroud or cover (Haynes call it a screen) on the distributor cap of my 1980 Mk1. This is earthed by a strap. Anyone knows what it's for and it it needs to be there ?

Thanks.

Hi Ken, I also had problems getting a rad for my 1981 Mk 1 injection as well. Got one from Heritage and wasn't the same. In the end I got one through Autodoc. It came from somewhere in Europe and was very cheap but fitted perfectly. Postage cost quite a bit !

Annoyingly the new WUR did not sort this problem. As before it starts well hot or cold and idles fine but there is no power (although slightly better when cold). It will hardly rev over 2500 under load even if my foot's on the floor. If I stop the engine and then restart it seems to go better for a ...

Quick update on this. Left car for a few months and started fiddling again a few weeks ago. Emptied tank (found to be clean), renewed pump and cleaned out main pressure regulator - no change ! So then took advice and looked for a pressure gauge. Managed to get a proper Bosch one on an auction site ...

Thanks for all the suggestions, lots of good info on link by blakey.

The below spec fuel supply must be a clue to the problem. To try and narrow things down what I'm trying work out is - could something in the metering head or incorrect system pressure be decreasing the amount of fuel returned to ...

Hi, having problems getting my Mk1 Storm to run properly due to insufficient fuel supply. When restoring the car I renewed the filler neck, fuel pump (Bosch - however it had been in storage for a few years), filter and tank and cleaned out the pipes, however it runs poorly and is down on power. Read ...

Hi, AVW in Caernarfon, north Wales are very good but quite pricey.

Hello, leather Mk1 seats need repair/ refurb. Anyone know of a company in north Wales/ North West who does this type of work ? Thanks.

Brief update - did some searching under part number (171121253D) and buycarparts.co.uk came up. It's a company based in Germany and is associated with another similar company called Autodoc. There were images of the radiator and it looked very similar to my original. A bit sceptical but the price ...

Have a look at the Haynes Golf GTI Performance manual by Tim Stiles (of TSR). Lots of good info re upgrade of various VW engines and engine swaps.
