Hi All,



I have a question about a 1988 90 Quattro that I just bought:



It had a warm start problem together with a sudden stalling problem.  In
looking at things after I bought it I noticed some water in the oil, to
be safe I pulled the head replaced the head gasket and went through the
head replacing the stem seals (head checked out ok) because it had
190,000 miles.  Got it all back together and I can not get spark.  When
I hit the key initially it will spark between the coil wire and ground
once (one spark) and then nothing.  I did some of the Bentley tests on
the coil and those came out ok.  Not sure if that means anything though.



I pulled the codes after cranking it for awhile and 4444 comes out.  I
did the output checks and that was good also.



Could the problem lie in the ignition switch, if so how would I check
that?

Any other things to check?

Is there a crank position sensor, I could not see one?

Anyone have a spare (known good) ECU and/or coil I could borrow?



Also, after cranking for awhile I pulled the spark plugs and they were
dry?



Any help is appreciated,
