Now that the temps are dipping below freezing at night, I'm starting to have probs starting the car first thing in the morning.
It takes like 5 or 6 cranks to get it started.

When it's warm(been driven), it starts right up.

When it's not below freezing, it'll take like 2 or 3 cranks to get it going first thing in the morning.

Are there any adjustments I can make to fix?

 

You *could* mess with the idle mix but thats just masking the problem which is cold atomization. Probably your injector diffusers or clogged injectors.

 

If the Water Thermosensor has a low voltage reading w/key to on or a reading at 5 volts then this could be your problem. And you want a voltage reading at pin 3B as well or that could lead to too little gas being injected upon start up.

 

what should the voltage at pin 3B be when the car is cold, and what should it be when its hot?

 

Pin 3B is the start signal and the voltage at that pin should not vary whether the engine is cold or warm. In an ideal situation it should read about 10 volts or so as the battery voltage is pulled down some when starting the car.

 

I'm with satch. Check the voltage for the thermosensor, and then stick your head under the hood and inspect the condition of the connection between sensor and harness. It's right underneath the alternator, attached to the back of the waterpump. Sometimes the pins remove themselves from the connector itself. Not having good connection there will definitely make your cold starts harder...
