7.3L Loss of power, lights and low MPG

It can be intermitten. I'd get a new one and try it. It's pretty much a one handed job anyway. 10mm bolt holds it in and it shouldn't be too bad. Also, I don't know what kind code reader you are using, but not all code readers will show diesel codes. I notice alot of posters on here hop right on board with, "It's the CPS" or "Check your valve cover gasket wiring." I say change it because that's what sounds logical to me. Not because I want to feel like I'm contributing by making you chase your tail. Good luck.

OK still no new CSP, the PT on my rotator cuff is killing me. I did go see a friend he had a superchip reader from his 7.3L so he read mine. I had a p0344, he tweaked it a bit and it ran better on the way home. He told me to try it and see how it liked the new program. At least now it somkes a bit, I am thinking the low sulphur diesel is killing me.

I will drive it tomorrow to my physical thearphy.

The P0344 code is most definitely your CPS. Mine went last week, and the black Cps for the 7.3 is only $35 out the door at O'Reilly's. I've put about 600 miles on since, and no problems. Takes 30 minutes, and that's taking your time.

so ive got the same problem and it only when it rains i went through 4 cps's before i just dodn't worry about it. i heard somewhere that it may have something to do with the water running down the side of the windshield and down the fire wall and dripping on the back of the ecu???? i don't know though
