Anyways, I gave it overnight, removed and replaced the fuel relays and unplugged/plugged in the Fuel Pump. Still not starting. It is wierd because it was fine yesterday (at least the idling was) and now it is turning over, but no starting. Starting to sound more and more like a fuel issue. Fuel Filter or Fuel Pump. I'm calling around to see where I can find a fuel pump, as for the fuel filter I am looking to amazon. I posted a link to a Mann-Filter Fuel Filter, but it doesn't say if it comes with the fuel pressure regulator or not. Does anyone else know about these things?


I figure I might as well change the fuel filter anyways since it has never been changed to my knowledge, and I have driven it almost 50k miles. As for the fuel pump, I am looking to see if I can get a used one cheap from a dismantler and replace it to see if that fixes the issue.
The shraeder valve is under the cap at the top of the fuel rail on the left side of your photo.
It's that little tit that is sticking up on top of the fuel rail.

Here's a Youtube video

Have a fire extiguisher handy incase you don't have a tight seal.

Shit...Now you scared me. Oh well. I have to do what I have to do. Let's hope I get a tight seal.

lol. Fuck that. Anyways, I am waiting on my dad to get home so that he can let me borrow his car to go down to harbor freight and pickup a gauge to check the pressure. Now, like I was stating yesterday, the engine was idling rough but was still running until it just died and didn't want to start again. This may sound like a stupid question, but would the car have a failsafe mode for the pump, essentially turning it off after a while if something isn't working correctly? Reason I ask is, if the car shows no pressure at all, could it be that the car has shut off the pump, or would it be safe to say that something (fuel filter, fuel pump, fuel relays) are done? I ordered a fuel filter from Amazon after searching online for results on that Mann-Filter brand. I also ordered jack stands (25 bucks, can't beat that price) so that I can jack it up safely on my inclined driveway. I am going to use Cinder blocks as Chocks behind the rear wheels and hope for the best. IF it turns out I have NO pressure whatsoever, should I purchase the fuel Relays FIRST before doing anything else? In other words, go from Fuel Relays -> Fuel Filter -> Fuel Pump? I found some cheaper pumps online for as low as $120.00.

I tried turning it on right now, and no dice. I sprayed carb cleaner and that started it up, so at this point, it seems to be a fuel issue, not an air issue.

crush - as in an accident... in case of an accident, the fuel related circuitry is being cut off at the battery terminal as part of the airbag deployment sequence.

you are not there - the BMW does not have a fuel trigger switch a la Ford... i set off that trigger once in my Ford Crown Vic by running on the shoulder rumble strips... nothing like that in your car

Ahhh. Crashed as in a wreck, not software crash. Gotcha.

So the fuel gauge read no pressure.

No pressure on Shraeder valve - YouTube

Then, just to ruin my mood, the thread for the schraeder valve broke.

The pin is still there. The thread is hollow so it is vulnerable but not leaking as long as you don't touch the pin. Still need to fix it, but it isn't damaged and appears good enough to keep for now.
