Welcome to the beginning of the E53 Project! This poor vehicle has been sitting for about 3 years because I basically thought it had busted timing chain guides which is a huge job and I was putting it off because I had other stuff going on in my life, but now it’s time to get this vehicle going. Before we jump right into the timing chain project, we first let’s properly diagnose exactly what is causing the no-start issue…

What new fuel pump did you get for this? Trying to pick one is a little more complicated than I expected
You got a friend in me. I'm seeking your mentorship. I have a 2008 BMW X3 3.0SI, that I want restore. I'm located in DMV area.
put a coffee bean in the tank for good luck
Wow, thanks for this. I was able to properly diagnose my X5 by referring to this very detailed video. I am no confident that my problem is the fuel pump wand ill now order the part. Thanks again!
After so much time and no thumbdown
You are the Man with good quality videos
quite a job you did….From Chile I´ve been watching your videos, following step by step….i got a bmw 530i 2004, and did all my work trhough your videos as a begginer, i`m at the point where checking my car i will let you know later how did go. the issue was bad starter and had to open the manyfold and found where the starter was…
I had a similar problem, but for me the fuel pump was fine, but the white(positive) cable does not have signal, and I was in the middle of BAJA, without cel signal, so I just get a piece of cable and connect to the white pumps( +)wire and the other end connected to a fuse on the rear fuse compartment. problem solved I made it to San Diego after 8 hours, without turning engine off
I have a E46 381i and this car had 2 fuel tanks and the main tank that has the fuel pump in keeps running dry and the car dies. The other side of the tank does not pump the fuel back to the mail side… Yet the fuel level sensor is fine as it does show that I have fuel in the tank. Help please
Brown never power on a BMW
??? When you initially found voltage at the white wire (brown is usually ground on German cars) that proved that everything about the relay was working.
Great to see the video back again! Literally lost count of the repairs I need to credit you for!
Wow this man knows his stuff.
So excited when there was no fuel comming from that tube!!
Watching this video even as an e46 owner and still being entertained proves that you still have much to give,please keep making those videos..
You even showed us that clamp kit thanks!!
Another quality video. BRAVO
Cool video I like those style clamps. As an observation you need to leave at least 1.5 to 2mm between the ears when using Oetiker style clamps . Essentially you over tighten them otherwise. Cheers
So good to see you back 50s Kid!
Welcome back Jason. We missed you.
Glad your back, love the videos.
Thank you buddy you’ve awesome trew out my journey !!!! Nothing but Love from Las Vegas
