definitely what I was thinking, although I'm leaning to another issue as the HPFP is pretty new. I think less than 30K if I remember the milage right when I replaced it

When I hear of hard start and/or rough idle with the 2007-2010 Cooper S models, the first thing that comes to mind is the HPFP...

Find out where the fuel smell is coming out from - tailpipe or engine bay or somewhere under the car. You may have a loose, broken or cracked fuel line that the main pump is pressurizing, but not providing adequate pressure for the high pressure pump, which would likely trigger the computer to deny spark, high pressure pumping or injector triggers, or even spark. Get under the bonnet and check all the fuel connections. do so with an assistant trying to start the engine, so you can detect leaks. (On my non-Mini9 daily driver, there is a hose going from the firewall to its fuel rail that periodically needs its clamps tightened and less often the hose replaced. On one occasion, I found the hose, a good quality brand, had a lot of tiny hairline cracks that oozed fuel.)
Try starting it with a little applied throttle (your foot lightly on the gas pedal) to eliminate the chance that it might be a throttle body issue. No throttle might allow fuel to be injected and a very rich condition resulting. The air flow sensors would also sense air NOT moving through the intake, which would trigger the computer (or confuser as AvE would call it) to deny start.

No new codes
since this started I noticed the battery seemed to be dying so just at the last resort I tried jumping it which didn’t work, and charging it over night which also didn’t help.
I think my next step will be checking fuel stuff, like filter, pump, hpfp

Hey everyone! I moved my car into the garage the other night, started final and drove it around my house into the garage. The next morning I go to start it it won’t start. Video attached shows how it acts every time you go to start. I also smell gas after trying to start it. I’m going to try and diagnose more today but figured I would get the ball rolling if y’all have any ideas.
no there are no new codes on the car (old codes that are from other issues I’m slowly working out)
as far as how it ran before and previous issues please refer to this post: https://www.northamericanmotoring.co...il-issues.html
I would have to double check but I don’t believe there are any new codes since I had made that post
The other codes I talked about are mostly voltage codes which is now making me this a possibly votlage regulated issue, could this have anything to do with the starting issue?
any help is greatly appreciated, thanks in advance!
