Ok, before we get to the main issue, let me list out what I've got.
2007 speed3:
Back in February the car started running real rough, a lot of misfires, and getting some smoke from the tailpipe when shifting. I replaced the spark plugs thinking that would help. It didn't. It got bad enough that I parked it and stopped driving it. About two weeks later I was gonna drive it over to a shop and have them look at it, but the car wouldn't stay running for more than 30 seconds. I started tearing it down a bit and found my spark plugs were coated in oil, and you could see gunk all over the piston through the spark plug hole.
So I got worried, and kept tearing down some more. Took the throttle body off and looked into the intake manifold.
I wondered where this all could be coming from so I looked around and found a little oil around/under the turbo. I also found oil leaking out of the intercooler. Well that basically sold me on the fact that the turbo was bad. Not going to confirm or deny that... I have a bad habit of convincing myself of things and running with them full force lol.
So a friend of mine and I swapped the turbo out with another ko4 that I had from a different speed3 that I had that flooded. We cleaned everything up a bit, and threw another set of plugs in and hoped we could burn out the excess oil since, hopefully, there wouldn't be oil getting in through the intake anymore. So the car started up, but same thing, it wouldn't stay running very long before it would die. It also had a lot of blow-by from the line that connects to the intake pipe near the MAF sensor. So we started watching the AP and noticed that right before the car would die, the fuel pressure dropped insanely quickly.
And that leads us to today. After a lot of reading I thought that I was losing fuel pressure because of either:
I had it running on jumper cables because the battery that was in it was super old and hadn't been charged. Well the car died after those 10 minutes because I took off the jumper cables. I tried to start it again, but nothing on the dash came on. I hooked up the jumper cables and checked battery voltage with the cables connected and it was around 12.7 V I think. After I took the cables off it dropped to 12.1 v. So I knew the alternator was bad.
So I replaced the alternator, got a new battery, and got my ever so hopeful self ready to drive my beloved car again after one more repair.
It didn't work.
Car only ran for about 5 minutes after that, and then died again. It would crank and run fine for about a minute. Checked fuel pressure and there was still a mysterious drop in pressure right before the car died. After replacing the alternator and battery, it threw a p2004 code, and a U code. I have had the u code for a little bit without any other codes, but the p2004 code was new. After several tries to get the car to stay running, it wouldn't start anymore. Fuel pressure on the AP was sitting in the 16-19 range and wouldn't build back up. So I let it sit.
After work today i jumped the connector for the fuel pump resistor, and I replaced the fuel pump and circuit relays. Car started right up and ran for about 6 minutes before it died again. I was able to start it a few times, but each time I started it, it ran for shorter periods. Then it wouldn't start at all again, with fuel pressure sitting in the 16-19 psi range.
The car is also smoking pretty bad out of the tail pipe while running. Very white smoke. Forgot to throw that in there somewhere.
Does anyone else have experience with anything like this? Any help would be appreciated. I just want my damn car back, I havent driven it since February.

- Bad hpfp
- Relief valve on the fuel rail
- Or something electrical
