  Thanks for the re: I was noticing you'r posts about
the TDC pin.
 Now that time has gone by and I've tested alot of the
system I do think that the sensors are my problem or
at least the pin and I saie that cause (and I posted
about this to the list)
 but a few weeks ago when all this hard starting
happened I was at a local store and was grabing
something from the pass side seat when my foot slipped
off the clutch pedal and the car lurched forward with
a nasty sound, after leaving the store I noticed that
my check engine light was comming on
so after pulling the codes I got the Hall Sensor code.
I did the checks per Bentley and found it working fine
but one of the fixes or things to check was the
Ignition Pin.
So I'm going to do that and report back, if it's the
pin thats damaged as well I'll need some advice from
you on how to fix it.
