It out. Will keep driving like this for a few days and see if I keep having problems. Was planning to pull my tune anyway as I understand there may be a new software update I should get before I install my FMIC. What software version are you running shockin?
I have 2.42 I believe

@ Shockin330i

Weird how that is happening, mine has 12k miles and I have only (Not tune related) experienced long crank a couple times. I hope you get your situation resolved.
Well you at least have to take off the canbus. but if you feel like something is wrong its always best to take tunes off.

But just because it doesn't for some reason, doesn't mean that the HPFP is failing.

I don't think its the hpfp. Weird thing is my car use to always prime when unlocking. Now I noticed that it doesn't do it at all. I'm going to let my car sit for about 10 hours or so today and see if it fails to start again. I'm going to take the car in anyway and have them update the dme again and maybe get the 2.44
