I'm still concerned about the fuel quality...if the old gas was stale, and you added fresh gas, you now have sort-of-fresh gas. Or sort-of-stale gas. Either way, these cars are sensitive to misfires- if the engine detects a misfire it will shut off that cylinder until the key is cycled. Too many cylinders being shut off will, of course, not allow the engine to idle. The stale gas will also foul the plugs. I'd really like to see you drain the tank and refill with fresh gas and flush it through the rail too. If not you're getting into a viscous circle of spark plugs in/out/cleaned/replaced/fouled/all over again

Just how old is the gas in the tank? How much fuel was old and how much did you add.
When you get it running do not beat on it with the crazy fuel mix, but personally would fill it right away with fresh fuel. Purging of the fuel rail taking out about a quart would also be warranted as per 55greasemonkey.

If your fuel press. Gauge has a release port on it, get a fuel sample in a glass bottle, lets have a look at it. Should be crystal clear. It should also smell strong but not like turpentine.

Yes , won't be long guys. One thing that did not look right AMG55tech was that the engine loading at 105%. You have worked on these longer than I but is it possible to strip or break the plastic gearing inside of the throttle body mechanism which would be telling the computer the car is running wide open, even though the throttle plate is closed, hence mega fuel and no air and no start, those plugs looked terrible for 10 miles of use, comments!

I personally have never seen it before, but anything is possible. That looked very odd to me too, thats why I suggested to check to make sure the supercharger would spinn freely (locked up supercharger causing extreme load on engine). But that is not the case and his supercharger spins freely. The gears should be checkable by simply moving the butterfly valve by hand. you should be able to hear the mechanism moving inside of the throttle valve and it should move smoothly and have a slight amount of restriction on it due to the gearing and motor. I would assume, if the gears are stripped, the butterfly valve will move freely or flop around with zero restriction on it. Wont hurt to check it.

Would like to see the throttle plate moving with the depression of the gas pedal, just to remove this from the equation. Also while doing this monitor to see % of TPS change. Those Bosch plugs sure were ugly, Need to see the gas sample also as commented on above. If the car had not been running previous I would swear someone has loaded it up with diesel fuel.

Just checked the TB, it will move with some resistance when the key is in the off pos., and you can hear the gears and motor like you normally would. When the key is on, it will fight against you to keep it where it is set. Haven't checked to see if it moves with gas pedal depression yet.
Also, with the fuel pressure tester, I got a sample into a mason jar, and my money says this gas is very well past its due date. Out of curiosity, I tried lighting the mix on fire. Compared to fresh gasoline I had for the lawn care tools (not premium), the fuel from the rail was very very poor in quality. The fresh gas lit easily from the fumes about 2 inches away from the puddle (size of a quarter), and burned for a decent amount of time. The fuel from the car would only light with direct contact to a flame, and made a decent amount of soot from burning it. My photobucket doesn't want to work, so I'll just attach the pictures here.
EDIT: I also wanted to add, the fuel did not at all, smell normal. It almost didn't smell like gas, it had a stale kind of chemically smell to it (Maybe a little bit comparable to turpentine). Hard to describe, but did not smell like fresh gas.

That definitely does not look good, is there a chance you put diesel fuel in the car by mistake. If not \I would hook up a hose from your pressure tester and with ignition on bleed about 2 or 3 gallons out of the system. After this I would put in 10 gallons of fresh fuel then bleed a quart out and try for restart of engine. Just how much gas is in the car, you stated before that you put fresh gas in and some octane booster, so how much was in the tank and how much did you put in. This I would put money on is your issue , how long has the car sat prior to your ownership 1-2 years,

The car does not get driven much, so that is why the gas gets old quick. I usually only keep it around a quarter tank for this reason. If I had to guess, the fuel in the tank (minus what I added), is about 5 months old, give or take a couple weeks. Before I added fresh fuel I would have guessed there to be about 5 gallons in it, and I added roughly 3 1/2 fresh gallons. So total fuel in the car I would guess to be around 3/8 of a tank. And I am absolutely 100% positive that no diesel or anything other than 93 (I don't even use 91 unless I have to) has been put into the tank.
And would it be possible just to turn the fuel pump on through STAR to bleed it from the rail? That would be much easier than turning on the key, bleeding residual pressure, and repeating 1000 times. I could imagine it would take a lot of juice too, so I would keep a charger on it during bleeding.

Okay now we are on to something, gas 5 months old should not look that oily/green but that is for another forum. When you have the tester on the fuel rail with the key on can you not depress the release button near the gauge so in effect there would be little pressure showing because you are bleeding it off through the line that you attach to the outlet on the gauge. Pressure is resistance to flow, with this setup you could get 3 or 4 gallons out in 5 minutes. Drain into a good container. Then add 10 gallons as stated flush a quart out then try to start after removing the gauge.
Also did you get new plugs?

Oops, just noticed in one of those pics that gas does look very green.. It was not at all green, I don't know why it showed up that way, the first pic represents it perfectly. And since I have all of the plugs out ready for replacements, I will go ahead and drain all of the fuel from the car. I am just going to install the bleeder onto the rail and rig the pressure release button so no pressure builds and just goes right into a gas can and then turn the fuel pumps on in STAR, until almost empty(I don't want to run the pumps dry). Then off to the gas station for fresh gas.
On a side note, what am I going to do with almost 8 or 9 gallons of bad fuel??

Drain all the fuel and start fresh. STAR will only let you run the pump for a short time without having to repeat the process,perhaps you can just hit F3 every time. If not, jump the fuel pump relay. When the tank is empty, pour 2 gallons fresh and repeat the process to flush everything.

Offer it to a friend who does not drive a benz! A few gallons mixed in with a full tank in say a Honda or Chev or Ford would not do harm but yours does not like it obviously, too sensitive to misfires and shutting down cylinders. Be carefull when draining fuel, remember it will still burn given the right ignition source, ie the battery charger, it sounds like you get what I mean, good luck
After the fresh gas just bleed about a pint then you will be assured that there is fresh gas at the injectors.
Fresh plugs on the way?

Already drained about 5 gallons through enabling the pumps through STAR. Works perfectly too, did not turn the pumps off once. Took another sample, and it was very similar to the first. I figured I would stop for a few minutes to give the pumps a break.

As far as giving the gas to someone else goes, is there any way I can test it to see if it would even work for them? I would hate to give someone 8 gallons of gas to find out it wont run in their car either..

Already covered, have a shop fan circulating air through two open garage doors. Would hate to see the E blow up from fuel igniting.. I'd blame it on the leaky senders....

NICE!!! Now we're getting somewhere!!! Time for some fresh fuel and get her started up. get some cheap cheap spark plugs to get it running, and once youve got it running and you feel all of that old a$$ fuel is out of there, pull the plugs and put some decent ones in and go from there. Dont bother putting good plugs in just to dirty them up once the engine starts cuz im sure there will still be some crap that will need to flush out of everything.
