Fuel Pump Issue?
Hey all, looking for some help to diagnose an issue. Over the last few weeks my car will occasionally (seemingly randomly) have issues starting. It will crank a couple of times before stopping. It will usually start after 3-5 attempts. I think the battery is healthy: it's only three years old. I've attached a video showing battery voltage before, during, and after start. No codes (other than P0420 due to downpipe) nor pending codes. It only happens maybe 2-3 times a week, and I drive it quite frequently.
2018 Stage 2 Audi S4 w/ 57k miles: Downpipe, intercooler, turbo inlet, and intake. All from IE.
I recently replaced PCV and spark plugs, but had this issue before I did that work. Any tips on diagnosing would be appreciated!
Other possibly related symptoms:
- the car feels a bit more sluggish than usual
- the engine bay seems a lot hotter than I remember it, but it's possible it's because I am just noticing it for the first time (and have been working on it a lot recently, so I've been under the hood pretty often)
