well recently my 2001 7.3 has be acting weird, somedays if its cooler then other,about 45 or below and the truck has been sitting 24hours+ it doesnt want to start, i wait for the WTS light to go off,and it cranks but sounds like its loosing power,and then i crank it again and it starts fine,no probs;but there is a good amount of white/grayish smoke, ive been thinking its the glow plugs,am i right?
