A bad connection at the sensor socket or a bad ground can have the same
effect. Temp 2 sensor though would be my first stop also.

Subject: Re: hard starrting when warm

All I can say is this...I have a 1.9, did the same thing. A reputable and I
use the term loosely, VW repair shop had mine for 4 months and could never
figure it out. They screwed up everything trying to figure it out. Fuel
pump, computer, ignition module, the works. Everything but the actual cause,
which I eventually figured out for myself. Turns out, if the temp2
sensor/switch fails, it tells the computer when hot that is is actually
cold. The fuel enrichment takes place and essentially floods the engine. If
you wait an hour or so, depending upon your environment, the engine is
actually cold enough for the faulty sensor to be effective.

Now, be aware this is my experience and from what I can tell, others as
well. This is my 2 cents worth. O'Reilly's and Autozone carry the sensor,
just make sure they get the temp 2, not the h20 sensor.

I shut it off and try to start it 15 minutes later, it will crank just fine,
but it does not fire.  If I turn off the key and turn it back on, it starts
right up.  There is no sputtering, etc., as if there is nothing wrong.  Any
ideas?

  I'm leaning toward fuel pump relays or the coil, but I want to get an
opinion before throwing $$ at it.  I also notice a large price variance in
coils.  What is the difference?  BD appears to offer a lower cost one than
other places.
