     When my distributer/HAL went I could 'occasionally' still get a spark 
     when I too went through the battery of tests.  Note your symptom, you 
     stated you would be driving and it would cut out so (going on the bad 
     distributer assumption) this would be indication that at a given 
     moment in time you have spark and the next moment you don't.
     
     When my 16v did what you describe mine went like this.  Out driving 
     when suddenly my tach would go from 4000rmm to 0 (stall) and jump back 
     alive via the momentum of the car.  It this a few times, then when to 
     near impossible to start.  After confiming fuel delivery, I changed 
     everything but the distributer (cap/rotor/plugs/coil/ICM).  The car 
     ran for a few days, then boom.  Would not start at all.
     
     Replaced distributer $200.00 and presto, I have put on 7000 trouble 
     free miles since.  The 16v distributers do go.  Between the HAL and 
     the leaky seal which can allow oil to come up through the rotor shaft.

Hi everyone. First off I'd like to sincerely thank everyone who sent me 
messages about my 87' 16v that would die all of a sudden. Well here's the 
update, if you're interested and I'll tell you - I'm lost!!!
     
I kept driving the car until one day it just totally died - turns over fine 
but wouldn't catch on. I went through all the troubleshooting routines as 
described in the Bentley manual. Here's what I've done:
     
- Checked for spark:  there's a decent blue spark on all four spark plugs 
so it's not ignition unless my timing is totally off, is that possible? But 
how do I check my timing if the car won't start!
     
-  replaced the fuel filter
     
-  fuel pump seems to make a healthy noise and I get pretty good gas 
pressure on both sides of the fuel filter so I don't think it's the fuel 
pump or the filter
     
-  checked cold start valve - fine, sprays on time, doesn't leak
     
-  checked resistance on the coolant temperature sensor - fine
     
-  checked the air flow sensor plate - lifted it up a little, still don't 
start. 
     
I love my car but this is driving me nuts. Why won't it start!!! Any ideas! 
Please E-mail. Again, thanks so much to all of you for help...
