Once it gets cold it won't start again without starting fluid. Similar issue on my '95 F150 with twin tanks...on the front tank, she would stumble and sputter to life on a cold start and after warm up, it would re-start fine. Rear tank it would start fine cold or warm...check your fuel pump, I am guessing it is starting to crap out on you. Share this post Link to post Share on other sites
CoolScoop 69 Report post Posted December 1 (edited) If it runs rough until it warms a little after you get it started, try replacing the idle air control (IAC) valve. Edited December 1 by CoolScoop Share this post Link to post Share on other sites

That was the first thing I went after when mine started acting up...no difference. Front fuel tank was weak....damnedest thing I ever saw. Share this post Link to post Share on other sites
theDuff 27 Report post Posted Monday at 11:14 PM How are the plugs? Spark plugs that are very worn do not like to start in the cold. Share this post Link to post Share on other sites
