Once started truck runs fine. Always started fine during hot weather. Now that it is 17 in the morning I need to restart it 4-6 times before it continues to run.
Sounds like the cold start solenoid. It is designed to keep the engine running at a set RPM until it reaches a specific engine temp.

The cold weather wreaks havoc on everything. I am thinking that the cold weather and your octane rating are not getting along, hence no error codes. Have you tried fuel drier and or octane booster?Since the truck starts when the temperature gets warmer, I would look at octane as the culprit. Try some octane booster and see if that helps. Let me know. Hope this helps.
Thanks;

check your tail pipe for a "clog" engine not breathing correctly.

You may have a problem with the contacts in the ignition switch (not key part), when you crank the engine a signal is sent to the fuel pump to run, when it starts and you let off the key another set of contacts keeps the pump getting power Through a relay), these are known as crank and run modes.

If this happens only when the engine is cold or cool, I would suspect a coolant temperature senor that has lost its calibration.
One way to check would be to have the engine controller scanned when the engine is cool then cold.
The coolant temperature should be the same as the intake air temperature. If the readings are not close to one another, change the coolant sensor.
The coolant temp sensor controls the fuel mixture when the engine is cold, normal or hot.
Good luck, let me know.

Hello there:
the way you are describing it it is sounding like the fuel filter is started to clog and might need to be replaced.
you may also want to look into a tune up i.e spark plugs and wires and rotor cap and air filter ect ect ok?
best regards michael
