Well guys, Im having issues with my 7.3l Diesel. I was driving it Sunday night from around 4-9pm and around 9 o clock i heard a loud bang followed by smaller bangs coming from the engine compartment. Truck Jerked back and forth a few times till i came to a stop and it sounded like it was struggling to stay running. I immediately shut it down to stop further damage. When i heard the bang it sounded like a belt broke and kept hitting the top of the hood. "the loud bang from the belt breaking, and the smaller bangs when the belt continued to hit the hood". I got out and inspected the belts found nothing. All the belts are fine. Started the truck, Heard a loud knock, revved the engine to 2k and it sounded like complete ****. took my foot off the pedal and the truck was struggling to stay running. I shut down the engine and called for a tow. The tow truck driver came got the truck, towed me to my local ford dealer and dropped it off. I get a call from ford after telling them exactly what happened and they tell me everything is perfectly fine. Injectors are perfect, fluids are fine, sensors are fine also. They can't find ANYTHING wrong. I don't know what to do. I know the truck is NOT fine. What should they look for? Its weird how it was running horrible for me after running it for 5 hours. And the next day its perfectly fine. Is it something internal? What should i do! Please help i want my truck back!!!


Thanks for the help in advanced.

Did the dealer run any diagnostics on it? They should be able to at least hear the problem. Maybe check for a bent pushrod, check fuel pressure, check HP oil pressure/duty cycle, check valvecover harness connections, check for DTCs. Cheers!

Dealer said they checked everything, they spent 4 hours running test on everything they could think of. Found nothing. They called me before saying the manager and service manager are going to take it for a long ride and see if they hear anything. Im just nervous its going to cause more damage if its something serious....

Sounds like the CPS , a very random acting misfire which can give all of us that terrible gut check .
When mine acted up ,it would buck,hiccup,cutoff and occasionally display a cel and then restart perfectly .Not much fun .
Have you replaced the CPS ?

Not that i know of, How much is a CPS? If its not that expensive i will have them replace it just incase.
