Well Scott, that depends alot on what year your truck is. It could be your cold start sensor or various other sensors. When it comes to sensors, it's really difficult to find out which one is working and which one isn't, without a computer. Are you getting any check engine lights? Is your truck carburated or fuel injected? If it's fuel injected, I would probably take it to a dealer for that one. Unless you have your own diagnostic computer.

It has to be something with your cold start sensor. But i'm a stranger to electronic sensors and all that. I wish I could help.

I'm still learning the ropes but the truck is 5y/o and u have put in a lot of stuff but 1) have u changed out the fuel filter 2) any contaminates in u'r fuel?
R u in 1 of the states that might be switching to that ethyl alchol additive?
Is u'r fuel line pressure up to snuff?
