From a post a bit earlier: "He indicated that the old injector ended with a letter B.".
Very interesting. The parts list shows the injector is supposed to be ????-9F593-B but mine has the same injectors found in the 1.5L but now discontinued. The injectors they replaced yours with are the current 1.5/2.0L injectors for many 2023 model year vehicles. It would be nice to get numbers from as many failed injector vehicles as possible.
That is the fuel rail part number it looks like.
Very possible that "B" is now a "C". Modifying the suffix when a part is upgraded is usually the norm.
Taken on the passenger side. The direct injection fuel rail is below the intake passages on the head.
Yes it is odd. There is no part listed at all for item 9F593B. It may have been removed to prevent re-ordering a part Ford is in process of replacing.
This may be slightly off-topic, but are there any other serious potential issues with the Nautilus? The overall reliability of Lincoln is relatively low, according to what I've seen. I love the Nautilus, but before I jump in I'd like to know if there might be any additional surprises.
There were some dead battery issues reported for the Hybrid early-on, but we haven't heard much lately, so that may have been an initial batch thing. Some Reserve and Black Label models (Hybrid and non-Hybrid) had noises from the rear that were caused by shocks that needed to be torqued or replaced. Again, that issue seems to have faded away after numerous early reports.
One thing to know is that the reliability of Changan Ford is relatively high. In fact, quite high in their market. The quality of build has been a thumbs up for all that have reviewed it, both consumer and professional.
Hi Guys! Update on my issues. I understand the new fuel injectors are working. They installed them yesterday and I see they drove it about 3 kms. (2 miles). My sales guy said that the engine sounds as it’s running normal now. I did get a couple of faults sent to my Lincoln Way app … service engine soon and drive train fault that are still staying on my app. The latest issue is now they found the 12V battery failed the test and now have ordered a new one. They told me when I picked up the Nautilus on May 3 that they had tested the battery and it passed then. What has changed in 2 weeks for this to happen. ( of course battery is on back order with no ETA). So there it sits in the service lot awaiting the next issue to come up.
That's mostly good news. The 12v battery might be just them covering their backs. I cant imagine the battery has gone bad that quickly even if it was drained by a problematic system. Ill bet it had a bad cell or 2 and voltage at some point dropped a bit low and they reverse charged. Might have happened during service if they ran a software update or just had accessory mode on for a while. The BCM should stop it from dropping but a bad cell might drop too low even before that.
The replacement service # will be the C suffix . The BA is the enginnering # which is installed on the vehicle after the cutoff date. Every part installed on a vehicle has an engineering # printed on it. The parts available to replace those are the service part # they are rarely the same number. In this case the BA = the C.
