i have a 2003 f350 super duty xl 5.4 litre engine, my problem is that when the truck is in the power position and u press in the clutch the engine starts and when driving each time i change gears the starter engages, ive swapped out the ignition cylinder, ignition switch, starter relay, and the clutch safety switch im having a difficult time figuring out this problem and any help
would be greatly appreciated thnx.

 

I'm not sure of what you mean when you say the truck is in the power position.


Can you interrupt the circuit from the ign switch to the clutch safety switch or the starter relay and see if you can isolate where the relay is getting it's feed while driving?
I believe the wire feeding the clutch switch is a red/light green wire. A test lite would be helpful to confirm which wire is feeding the switch before the pedal is depressed.
Once you can determine where the feed to energize the starter relay or starter is entering the circuit while shifting you can separate the wire/interrupt it and you should be able to determine if the feed is before or after that point. The factory diagram is not too helpful for gasoline engines with manual trans.
I will try to stay on this with you , maybe 2 heads will be better than one.

 

by power mode i mean auxillary power i think the position where u can run ur stereo n all the other things like that in ur truck just before u turn the key to start

 

could it be sumthing to do with an aftermarket cd deck in the truck?

 

I don't know if the cd deck is related to the problem, but I can tell tell you , late model Fords with computers don't like aftermarket add ons. What if you temporarily disconnect the cd deck and see if that has any bearing on the problem?

 

ya im going to try that the next time i can wrench on er n its not the shifting thats the problem its just the clutch that engages the starter everytime it is depressed.
