2001 Ford F-150 crank no start condition. Between June and August of 2003 my Ford F-150 has been towed in three times and not started at least two dozen times. The first dealer replaced the main fuel relay. The second time it was towed to another dealer and after five days could not reproduce the problem, and I picked the truck up. Two days later the same thing, this time I had the truck towed to my house. A few hours later it started. At this point I'm getting very irritated. After going back thru this whole thing I started thinking it had to be this main fuel relay and decided to do some testing on my own. I work in electronics and so I got a couple tyco relays and a can of freeze spray. The next time this happened I pulled the Ford relay and replaced it with a new one - the truck started right up. The next time I get the can of freeze spray out and cool the relay and the truck starts up. Im finding this to be warm weather related and every time it get hot outside I can plan on the truck not starting after driving a short time and then shutting off. If the truck sits by itself long enough for the relay to cool down it will start I think Ford should come up will a long term fix for this problem instead of replacing relays.
