6/21/22 Update:
I’m back in the saddle again!
Just a few days after my Bronco returned home, 3 local friends and I conquered the very same trail where the fuel pump failed.
A detailed ride report is posted here, including the trail map and over 30 photos and videos.
6/13/22 Update:
The vehicle was out of commission for 10 days (1 day for trail recovery + 9 days at the dealership for repairs). Replacement of the fuel pump and fuel pump control module were covered under warranty (N/C), and replacement of the wheel speed sensor that got pinched was not covered under warranty ($176, my total cost).
The Technician thinks the Bronco's fuel pump is a good design, and this was likely just a random part failure (i.e., infant mortality) that also led to a failure of the control module.
Details of the repairs and costs are documented here.
6/10/22 Update:
Repairs are complete, and she’s back home again!
6/9/22 Update:
Fuel system repairs are now complete, but wheel speed sensor must also be replaced.
6/3/22 Update:
Fuel pump failure confirmed. Covered under warranty. Parts have been ordered (ETA TBD). Loaner vehicle was provided.
6/1/22 Update:
The trail recovery was successful; now being serviced by local dealer. (Photos of the recovery here.)
5/31/22 Original Post:
My Bronco (2.7L) died today, deep into a remote trail… about 4 miles into a 10-mile-long trail with steep elevation changes, tight turns between narrow groups of trees, and deep mud holes.
That’s it below… hood up, exactly where it died, going down a decline with 21 degree pitch, trailing behind @kodiakisland's Bronco.
For background, @kodiakisland and I were scouting potential trails for the next NWA trail run on June 14th, and @kodiakisland had briefly stopped for a photo, so I pulled up behind him with my foot on the brake. When the engine started to lug, I put the transmission in neutral, engaged the electronic parking brake, and then put the vehicle into park, and it immediately died.
Numerous attempts were made to get it to re-start, but the engine appears to be starved for fuel. The first thing I checked was the fuel pump fuse (Fuse #4, 30A, in the Under Hood Fuse Box), which was fine. The tank was 3/4 full after being topped off this morning with half a tank of regular unleaded before departure. No signs of water in the fuel tank. Popped the cover off the air filter housing and confirmed that the air filter is not clogged or otherwise blocked. The battery is fully charged and alternator is functioning well (i.e., both confirmed by meters on the IP display, 12.4V on battery, 13.3V with alternator charging under load at speed). The starter fires continuously like normal. The crankshaft turns smoothly, and the engine tries to fire, and sometimes does for one stroke, but then dies again. I also disconnected the battery and waited 20 minutes before retrying, but the results were the same.
My instinctive guess is a fuel pump failure (possibly infant mortality; 2,490 miles on the odometer), based on other recent threads posted on the forum, but I haven't had a chance to pull any Diagnostic Trouble Codes (DTCs) or study the Technical Service Manual (TSM) for other possible problems. The vehicle is well beyond cell phone coverage, so it is unlikely that any DTCs would have been uploaded into the Mothership’s tracking system. If it's a fuel pump failure, that is going to present a difficult trail-side fix, because the gas tank will have to be dropped to access the pump.
Unfortunately, it's also going to be difficult to tow out for recovery, because of the aforementioned difficult trail access.
So the bad news is we pulled my Bronco off to the side of the trail and temporarily abandoned it deep in the woods this afternoon, and it is sitting on the trail side all alone in the dark tonight.
The good news is I hitched a ride home with @kodiakisland (Never wheel alone!), got some great photos, and saw three deer today!
