I have an 02 f250 diesel after turning key off truck it keeps running for about 10 sec.
at idle, its dies after 10 sec or if I give it throttle any ideas on the problem? also engine light came on with code 1690 wgs so replaced after testing. it was good for about a week
then same code any help?

 

does it have a turbo timer on it?

 

or your fuel shutoff solenoid?

 

shutoff solenoid shouldn't do the ten seconds then go off. i'm gonna say turbo timer

 

no turbo timer on truck, thanks

 

does it have a remote start installed? if its not that then i have no idea what else it could be??

 

^thats a good one! I wonder if there is indeed a remote starter installed.

 

no remote starter may be computer problem?

 

Can you get a video of this? I have been avoiding this thread for a few days because I have no idea what could cause this... When you turn the key off the PCM and IDM stop getting power, once that happens, no more fuel...

Only thing I can think of is leaking oil or fuel into the cylinders, but hitting the throttle should have no effect on this...

Kinda got me stumped!

 

Does the rig have PATS?
