2004 Screw won't start_sometimes
 

Hey guys about a month ago my truck would not start. I turned the key, everything on the dash lit up like it was suppose to but when I actually tried to crank it there was nothing. The anti-theft LED did not flash rapidly or anything. After a few other tries it cranked. I also tried my other set of keys and it still gave me a no crank condition. I finally took it to the dealership( under my extended warranty). They cleaned the battery posts and checked it.
The dealership actually replaced the starter I guess thinking it was the cause.
Well a week ago it did it again just when I was trying to get to work. I tried several times. Everything lit up like it was ready to crank but nothing happened. It says nothing. I had it to to the Ford dealership down the street.
When they first looked at it cranked.They have had it a week and everytime they tried it it cranked. I'm puzzled and they are too. I have it back now and I guess we'll see what happens. Anyone seen this problem or have ideas?????
Hate to be somewhere and have to deal with this crap:help:
