[s-cars] How to dump codes?

[chris chambers]

Paul,

I had the same symptoms, I'd bet money it's the CPS sensor. When the
CPOS sensor "fails" if the car is already running it will stay running,
but it should blink the CEL light. If you shut the engine off it wont
restart.

Mine was intermittent and didn't blink any codes for quite some time
until it just died. One constant wsa that it acted up when warm and
seemed to work when cool, so you might try cooling your CPS with a
little water just to see if it would start.

When mine finally did blink a code it was for the #1 fuel injector, not
for the CPS, I think mine was failing due to the bad plug.

You can blink out CEL codes using the instructions here:

The CPS can be purchased from the dealer $$ pricey or there is a 
known replacement that you can get from bbautomacao or perhaps from
another list member that bought more than one on a Group buy, if you
can't find one let me know I have a spare in storage in case I 
expereince this again.

There are several good write ups on replaceing the CPS sensor here:
