  post locked   2014 Cadillac ATS 2.0 - High Pressure Fuel Pump Failure  

Cadillac ATS 2.0 135,000miles currently. My high pressure fuel pump essentially had a catastrophic failure. The, i guess bracket(?) part that gets bolted to the engine has cracked and broke in half along with at least one if the mounting bolts to shear off. Any chance some metal shrapnel is in my engine now? Thats what i was originally told, but from what i’ve seen it seems like a small chance.

Otherwise what i’m hearing is to check the cam follower(?) and possibly the cam next to it. Thanks in advance for any and all help!

Nothing got into the engine.

I'm more concerned about what actually broke. Was it part of the head or was it a replaceable external part?

I hope the picture upload works. What is circled in purple is what has cracked in half and i currently have it home with me. The bolt circled in green is the bolt that has sheared off. so right where it attaches to spray into the engine. my apologies if i'm hard to understand this is my first vehicle and i'm learning as i go. Thanks. if you need any more clarification ill try my best!

That won't cause any problems. That is the end where the cam drives it. The fuel comes out the threaded end.

It has a gasket and an O-ring so the broken pieces could not get into the engine.

So all i would need to worry about is getting a replacement fuel pump in there? Am i correct in saying there would be a Stainless steel line connecting to it? Theres a line we were originally thinking was the issue and it was stating it would need replacement if it was ever taken off. Thanks

I don't know the condition of your line or why you would have to change it.

If you plan on replacing this yourself you have to be EXTREMELY careful bleeding off the pressure as there is over 2000 pounds of pressure in those lines.
