I have a 2000 7.3 and it will just stall at a stoplight and when you go down the highway it cuts out and the service engine soon light comes on but I took it in and even though the light was on there was no codes showing on the computer.
If this is a cps problem will it show a code?Also could this be a fuel filter problem and thats why there is no codes?
Also my door locks wont work right it acts like there isnt enough voltage for them to work but the truck starts just fine?

 

Where did you take it in to? If the SES light is on with the engine running there is a code. If it's only on when the engine stalls and goes out as soon as it fires it's acting like it's supposed to.

Codes or no codes I think the cam sensor is the logical place to start.

You could try resetting the GEM module for the doorlocks.

 

i second the cam sensor.

gem mod for the door locks?? a superduty glitch???

 

Grasping at straws...figure it's cheaper than replacing switches.
