What if your car dont want to start on cold mor and the code read out was PO171

Hello, is your truck a four-cylinder or six cylinder model? If it is a four cylinder model, then it indicates that there is an engine fuel trim lean code occurring. This could be due to a massive air leak which can also cause a cold start issue. I would check the air box, intake gaskets and related components to see if there are issues here. That code indicates that the engine needs more and more fuel to stay running properly which is because there is too much air present.
