Armada fuel pump faulty connection
Summary of the thread
The 2023 Nissan Armada is experiencing engine issues, including failure to start, stalling, rough running, and increased fuel consumption, with a check engine light indicating fuel pump errors. The initial suspicion is a defective cable or plug connection causing intermittent power delivery to the fuel pump. A similar case revealed that a faulty connection at the fuel pump was the cause, which was resolved by tightening the bolts, suggesting that checking and securing the fuel pump connections could be a potential solution.

Thanks for the quick response! Fuel injector, you say? Interesting. The error code specifically points to the fuel pump, but I know those codes can be misleading sometimes. Did your error code also indicate a fuel pump issue, or was it something else? Any further detail would be a help.

You know what? It WAS the fuel pump on mine, you are right! My mechanic said there was a faulty connection, so he just tightened the bolts. I would definitely get it checked by a workshop though!

You were spot-on. I followed your suggestion and had it checked at a workshop. Turns out it was indeed a faulty connection at the fuel pump, just like you described! They charged me 95€ to fix it. Thanks for steering me in the right direction; really appreciate the help!

Sounds familiar! I had almost the EXACT same symptoms on my Armada. Check Engine light, rough running, stalling… the whole shebang! Is it possibly the fuel injector?
