Greetings Diesel Lovers!
Ok, kinda stumped on this one.....I've had Several W-210s, all diesel. My current one is a '96 NA motor with the edc pump. I had a fuel leak at the shutoff valve, just like Every car I've had, pulled the valve, replaced the orings and life was good! On my way home, one of my fuel lines popped off due to the clip breaking and Completely filled my system with air! Trailered it back to my shop, fixed the fuel line issue and FINALLY got all the air out and running Perfectly. Life was good! While putting everything back together, I soaped it all down with Simple Green to hose off All the diesel that covered my bay. Drove it to the DIY carwash and gave Everything a good cleaning under the hood.....just like I've done Dozens of times. Pulled out of the diy wash and went through the drive through wash to clean up the rest of the car.....still good. Got through the wash, went to pull out on the street and NO PEDAL Response!! Limped it around the corner, checked everything I could think of and got towed back to my shop.....again.
So it was throwing a hard code for the EGR circuit, (i think po-403) and as Soon as it's cleared, it pops Right back up. I have dried every connection as well as unplugged & plugged back in Every connection under the hood....electrical And vacuum! Still no pedal response At All. I pulled a throttle servo off my '99 to see if the pedal servo was the cause, and didn't change Anything!! Just to be clear, it will Touch start and idle like a New car! It just Won't do Anything Else!!
I'm Stumped!! What can cause a Complete lack of pedal response?? ANY input would be Greatly appreciated!!
