Difficulty Starting In The Morning
Good day everyone,
Bought a 2008 LR3 V8 HSE, 150K miles last November via auction. I've had to work on the air suspension (front drops with 24-48 hours) and also I've been chasing some lean and rich codes (P0174 & P0175). Asides that, it drives well and is in decent condition.
In the last 3 to 4 weeks I has required a few attempts to get the engine to start. Normally it would start the first time without trouble. Now I have to try once or twice before it gets going. Once I do get it to start though, it is fine for the rest of the day. Next day, the issue comes up again.
I'd like some advice on what are the likely causes for this so I can fix it please. Thanks!
(I am going to try adding a video I took some weeks ago when I experienced this issue. I hope it can be viewed)

I tried to attach a video I took of what happens. I dunno why it's not uploading. Perhaps I'm missing something. But anyways, here is a link to the video

Hopefully you can view it this time. Thanks.

Almost sounds like a defective check valve in the fuel pump, causing the system to bleed down. So then you are, in essence, priming it every time you have to start it. If it was recently started there is still residual pressure so it starts easier. Just a guess though, but thats what is sounds like.

Also, out of curiosity I have experienced the vehicle stalling at times while moving. Typically after some, shall we say, 'spirited' driving. If then I need to slow down to a crawl or stop at a light sometimes it goes off. So far anytime it happens it always starts again but it is bit worrying. Could the stalling be fuel-pump related? Thanks a once again.

Well I cant say its the fuel pump for sure, it could be any number of things. But poor starting and stalling do sound like fuel related issues. If you have ANY codes, we need em. It could be something like a loose EVAP hose which is causing a large vacuum leak, etc.
I had a bad fuel pump a couple months ago, turns out the pump was fine but instead a wiring rubbing through since the day it left the factory. Just a matter of time before it corroded enough and failed. So ya never know sometimes. Its a pain figure out random issues.
