Four problems related to ignition have been reported for the 1999 Ford F-350. The most recently reported issues are listed below.
I havea 1999. 5 Ford F-350 diesel crewcab dualley truck. On 05/15/2007 while driving on the freeway noticed a loss of power. I got off freeway, and truck was idling erracticly and roughly with loss of power. The next day truck started up like normal. I test drove the truck, and same symtoms occurred. This time the check engine light came on. I changed the cam positioner sensor (cps), and reset the computer. I test drove the truck with no problems I had before.
I was driving and my truck stalled before getting to a complete stop. I was about to reach bumper to bumper traffic. Luckily there was grass on the right hand side and I pulled in there to avoid hitting a car. Had to go over the sidewalk. After turning off, I tried to start with no luck. After 10 minutes I tried again and it started. A little down the road same thing happened, it stalled. Happened like 2 more times until I got to work. Called my mechanic and he stated that the cps usually goes out and he bought one for me. Installed it and it worked. Just waiting for the next time it happens as I have read these things give out all the time.
Prolonged crank/no start.
April 2nd of 2004 driving at 30 mph and coasting to a stop sign the number 3 spark plug blew out of the right side cylinder head of my 1999 Ford F-350 with a v-10 engine in it. Ford in kingman,az. Installed a reconditioned cylinder head that had a spark plug blow out of it and a steel insert was the fix for that cylinder head. I was given a reconditioned head with the insert in it and told by the Ford mechanic in kingman,az. That it is just a matter of time before it blows another spark plug out or sucks the steel insert into the engine. I sinserly hope I'm not 100 miles from anywhere when this happens again. I also hope it's not going to happen on the way to the hospital trying to help someone. This is a vast problem and can easily be researched on the internet by simply typing in "Ford v-10 ,spark plug". Ford knows this is a casting problem with the aluminum heads having only 3 thread count in each cylinder hole holding each spark plug in.
