Subject: [928] Update – Intermittent Stall After Start on 84

I don't know if you remember our past messages about this, but I wanted to
let you all know that I think I have finally found my problem.

Background:  Car always starts very quickly warm or stone cold.  When
cold, it sometimes wouldn't stay running, even though it continued to
restart quickly, and will do so indefinitely.  After an overnight, it
might stay running after the second or third try.  After sitting for a
couple of days, it might take five or six tries.  Sometimes it would
simply start and run the very first time regardless of how long it sat. 
Whenever it finally stayed running, it always seemed to run just fine. 
Recently, it quit all together.  I must have restarted it literally fifty
times while troubleshooting it (awesome Interstate battery), and every
time it started quick but died after about 1.5 seconds.

Solution:  Once it finally failed completely, I found that the fuel
injection relay (XVI on my car) was bad.  I set up a bench test, and sure
enough, it wasn't pulling the contacts in when I put 12 Volts to the coil.
 I bought a new relay (928.615.119.00) from the local Porsche dealer
($14.38 + tax), and was right back in Bwwaaahhhssness.  It's been fine
ever since.  I've never really heard of a relay being intermittent, but it
sure seems to be the case this time.  I realize there may be some other
compound problem occurring, but it sure would be a coincidence.

So does all this seem plausible?  Do I have a cold start injector
independant of the primary fuel injection control, that is enough to start
the car initially?   All I've ever had to do is bump the key and it is
running, hot or cold.  It apparently just wasn't always making the handoff
from the crank mode over to the run mode.
