hard cold starting

[Ron Wainwright]

  Ti,

  It's just that you mentioned it in a post you sent
to the list on hard cold starting, but you saie there
is no thermo-time switch for these cars know. I'm
confused. It mentiones in the Haynes I have for the 5k
84-88 that the thermo-time switch energises the cold
start valve for a short time.
 Anyways I did replace those sensors with the one
wire,
ones next to the PS pump braket and the other one is a
little further down the block, ISV control and ECU
control like you saied.

 I've gotta check the warm-up regulator & cold start
valve next my car is having a hard time starting cold
as of late. Do you have any aditional advise on where
to start,
 I have to help the gas pedal to keep the car started
when the car is cold or the car will die, but after a
few minutes it idles around 800

Was just confused by all the terms for sensors and
such from what the books saie and from what people
saie.
Thanks
Ron
