Re[2]: Cold start problem...

["CHRIS AHOLA" <aholact@songs.sce.com>]

     I had the same problem with my '87 5KCSTQ.  It turned out to be a 
     bad thermo switch for the idle stabilization system.  Some days 
     the car would start and some days it wouldn't but it always 
     started when warm.  
     
     If you have the same car as me you can try this quick check to 
     see if the thermo switch is bad.  Near the front of the engine on 
     the drivers side you will see two thermo switches with a single 
     wire running to them.  One switch is in plain sight the other is 
     located under the hydraulic pump.  The switch under the pump 
     sends a signal to idle stabilization control unit mounted under 
     the dash.  Neither jumper the two switches with a wire or 
     disconnect the wires from each switch and reconnect the wires to 
     the opposite switch.  Now start the car when it is cold.  If it 
     runs OK, it was a bad thermo switch, if not keep looking.  It 
     could be that you need to replace either the stabilization 
     control unit which is mounted under the dash to the left of the 
     steering wheel or the stabilization control valve which is 
     mounted under the hood (a.k.a. bonnet).
     
     If you do need a control unit call me I have one for sale.

I just had the battery replaced and put in 10W40 (to replace 20W-50) and the 
car starts more easily now when it's cold outside.
