04 E55 amg w211 put in new fuel pumps now I'm having other troubles

I APOLOGIZE FOR MY BAD GRAMMAR* as actually using my voice to text seamless thread in a hurry on my way home just driving the car truly apologize for any inconvenience hope everyone understands I just LOVE this car more than ANY 1 that*I have ever had l, and I've had*over 60 cars seamce 1996.



Okay guys, I would**greatly appreciate any help I can get from ANYBODY here.

* *I have a 2004 E55 AMG Mercedes that sat for about two months,* because I lost a part (the lid/top) to the fuel level sender unit. I finally got it all back together. I put new fuel pumps,*new fuel level sending unit with new filter and everything in it during all this. Also a new pigtail for the wiring harness. All of it.

* * Anyhow I got it all back together and proceeded to try &*start the car, it took about 7 trys turning it over before it finally started. But when it did in deed finally start, it acted as if*it wanted to start but wouldn't.* Once it did finally start it would only run for a few seconds then die, (Personally guessing the hard to start problem was just air and the fuel lines) sounding as if I was on the throttle then off and on and off*ect... but I was not hitting the gas at all, then It would die. ( again thinking that part was just air in the lines from changing out fuel pumps ect., but I want to be as detailed as possible in my description of this problem.)


After that, It started to run smoothly at idle.*but once I tried to do anything except idle I.e. drive it or even rev the motor AT ALL,**It would hesitate ENORMOUSLY hard,*and act*as if it would die if I did not let off of the gas.

So when I finally got to try to test drive it thinking it may just need to stretch it legs after being cooped up in my garage for the past 3 months, when I would give it ANY more than 1/4 throttle**it act like it was going*to die/stumble, kind of acting as if somebody was covering the air intake COMPLETELY then pulling their hand off once I let off the gas.

* * * *So I drove it VERY ridiculously easily for around*30 miles,*it could*get it up to highway speed, (very slowly) but it just wouldn't go like it should,**If I gave it more than 1/4 throttle or down shift it would stumble/ try to die.


* * THE OTHER PROBLEM is that*it's not throwing ANY check engine lights or codes or anyting,*it hasn't fully died*at all durning all of this.**I have checked most of my sensors related to this,*they are all seeming to read good, cleaned my throttle body,*reset throttle position sensor, cleaned map sensor*and took off the*intakes*thinking it may had been*a leak on the intake, so I put in new gaskets and checked all vacuum lines for leaks.*


* Now*this*is*the part that is really confusing me and or making this problem hard for me to figure out or diagnose, since it is not throwing ANY check engine Lights or codes..*though*I am slightly hampered to*only*having the use a*Dash Command app to check for codes*with. But it (Dash Commander) is*saying that everything is A-Okay, even though I cant give it*any more than that 1/4 throttle*or maybe even less without it wanting to die.

* *I will try to post pictures of*the Dash Commander screen while running and maybe even a video exactly what it is doing while it's running,*if I can figure out how to do so.*


Please let me know if there's anything else that I need to post, or if there is any information I may have left out, that you all could use/need to know*to help me with this situation.


Again I apologize to Those who tried to help*me when I first posted this thread. I apologize for my grammar & that I am not the best literary person in the world by any means.*I am just a pipe welder / want to be euro mechanic.


Hopefully everybody can get past my* horrendous grammar etiquette*and*help me get my baby back on the road. Thank you to everybody for all of your help.* I am a huge fan of the MBWORLD Forum in EVERY way. This is definitely the best sight I have ever encountered,*the people in this* forum are awesome and very knowledgeable and or helpful.*I very possiblely wouldn't still owen this beautiful piece* of automotive*artwork if it weren't for the people here. So again thank you ALL for EVERYTHING!


* * * * * * * *THANK YOU ALL!* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *DOUGLASS M.* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * ENRIQUEZ.* * * * * * * * * * * * * * * * * * * * * * * * * * * * *
