my truck starts right up on the coldest days. the problem is if i dont let it warm up to it is high enough it will stall.never while moving.no big deal except it now has to sit for 15 or twenty minutes.sometimes it doesnt stall to i get to the nearest intersection.the honking behind me doent seem to help. i have to let it warm up on mild days even.a mechanic suggested the fuel pump but i am sceptical.i have two tanks and i switch back and forth but no luck.im the only person still sitt a work.every other vehicile i have had ihave been pretty much able to jump in it and go.or at least start it right back up if it stalls.thanks
