So first off I'd like to say i just joined DF so bare with me a bit. Anyways on to the dodge...I just got the truck not to long ago, never gave me a problem till now. Just past few days its been gettin colder and past couple mornings i have had some really hard starts. I first noticed it when i hit the command start then walked out a few minutes and the truck was still tryin to start itself. I shut off the command start and tried myself...no go. She would whirl over no problem but would fire a couple cylinders and then die. I finally got her going after givin her a little gas, ran perfect all day after that. (figured the command start may have just flooded her)

Then this morning she did the same thing again except i didnt use the command. She would not start until i gave it some gas but i also had to hold my foot on the gas til it warmed up a bit cause it wouldnt idle on its own. I am thinkin TPS? but i have also been told could be the cam and/or crankshaft sensors? Thanks guys any help is appreciated.

If it runs good once it starts and warms, cam and crank sensors are probably OK. I would be looking more at IAC, and TPS.

Hey thanks...yea i just got out of the garage...im pretty sure my TPS is good, after looking around i figured it was the IAC valve like you said, i think cause its cold it just needs to be cleaned out or i might have to buy a new one, and if thats not it i'll also replace TPS hopin its one of the two. They are both farely simple/cheap fixes so im not to worried. Thanks again!

Throttle Position Sensor. Drivers side of the throttle body, throttle shaft turns it.

Either no spark or no fuel. I am willing to bet on the fuel pump. How many miles on the truck?
