Dan Lund Posted November 29, 2019 Share Posted November 29, 2019 97 explorer 5.0, no start cold unless starting fluid is used. It will then start and run fine. Once it gets cold it won't start again without starting fluid. Quote Link to comment Share on other sites More sharing options...

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. Quote Link to comment Share on other sites More sharing options...
CoolScoop Posted December 1, 2019 Share Posted December 1, 2019 (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, 2019 by CoolScoop Quote Link to comment Share on other sites More sharing options...

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.

theDuff Posted December 2, 2019 Share Posted December 2, 2019 How are the plugs? Spark plugs that are very worn do not like to start in the cold. Quote Link to comment Share on other sites More sharing options...
