Buckeye Charly Posted November 18, 2010 Share Posted November 18, 2010 Florida Temp at 45 deg or below, eng spins strong but will not start until temp is up to 50 deg or higher. After sitting overnite, initial attempt will produce about 1 sec of running then dies out and will not start again until it's warm out. Just got it out of the shop yesterday. New Fuel Pump, new Ballast Resistor, new Idle Air Sensor, TPS checked and cleaned, all fuel lines checked, new fuel pump then removed and shop checked for pressure (OK). Drove it yesterday, multiple starts and stops all day with ambient air temp around 70 deg. PERFECT. Let it set last nite and this morning with temp at 39 deg, no start (except the 1 sec run). Will let it set until later this morning when it warms up to 50 deg and yep, it will start I betcha! Any ideas? MAP Sensor? TPS voltage?, ????? I am ready to put a 4 sale sign on it. Too bad since it is a good straight truck, new paint, 5 spd, good glass, fiberglass topper, but I don't need a gray yard ornament! :help: Quote Link to comment Share on other sites More sharing options...
