i have a 2003 7.3 powerstroke driving it today check engine light came on. 30 miles later stopped and when we cranked it back started running rough like on four cylinders. took it to advance with the light on had the code reader put on it and nothing showed up and couldntget the computer to clear the code that they couldnt find either. came home top seed 45 and took forever to get there. if anyone has any advice please let me know i will try anything not to take it to the dealershi and get ripped a new one. thanks.
 
Check with your dealer before you buy a CPS. They had a recall on this.
 
I carry a spare in my glovebox with a 10mm. I'm thinking the PO may have already replaced it. At the very least I might be able to help somebody on the side of the road with it one day.
 
Sometimes when cps goes out it won't run at all check injector harness they go in each value cover gasket there's a plug in on the outside and inside the gasket mine came unplugged under the value cover it was running on 4 cly plugged it back in and wire tied it back and that was 3 years ago you can use a temp gun to see if one header is not firing
