Hi

I have a 1984 GTI Rabbit.  This morning the car started fine then died after
about 5 seconds.  It started right back up and then it died a few seconds
later.

So I started it a 3rd time.  this time I held my foot into the gas pedal a
bit and it started and ran at about 2000 rpm.  I held it there, after about
10 seconds it dropped down to about 1800 rpm then after another 5-10 seconds
it dropped down to about 1500 rpm, and with time slowly the rpm came down.
I just took my foot off the gas and let it die.

So I think it might be fuel related.  The fuel pump is ok as I put a new one
in a few months ago.  I have a funny feeling it is the warm up pressure
regulator.  And I have a few spares as I've owned 3 rabbits a 1980 then a
1977 now the 1984 gti.  I think I might just swap the warm up pressure
regulator as it only takes 15 minutes.  And if that doesn't work start
troubleshooting from there.

Anything else I should look at?  I will inspect all electrical and vacuum
connections too.

Thanks
