Got a fuel feed pressure fault but it's been coming up for months. Cruise just stopped last week
Customer reply replied 4 months ago
Not a water in fuel problem. New filters, new fuel.
Thanks for the update. The most common cause for cruise control failure are faulty clutch or brake switches. If the wiring or switches have failed it will disable your cruise control functions. I would also test all your fuses and check your relays as well. If you have no other fault codes 4 speed sensors or throttle position sensor, etc. Then check your Clutch and Brake switches for proper operation. Most shops would just plug a laptop in and be able to watch switch status whether engaged or disengaged live right from the laptop. Let me know the results. Please remember to take a moment to write my answers as that is how the site credits my time for helping on the site. Five-star ratings in bonuses are always greatly appreciated.

Thanks. My truck is an automatic by the way.
Thanks for the update. That would mean that the TCM or transmission control module communicates with the engine ECM and can affect Cruise. Speed sensor signal is also important. If your brake switch is okay and wiring is okay then it is best to have the scan tool connected to be able to monitor switch status for much easier troubleshooting.
