Hey Guys I have a 1992 Mercedes 600SEL that I just Imported from Japan Sharp Car With all the gadgets and Rust Clean but I have no power Steering !!!

Check The power steering fluid is good and no leaks one Shop told me I need a power Steering pump the new one is about $1600 so I found the used one for $150 after 5 hours of labour its the still same problem but now it maybe feels even harder to steer or maybe I am just pissed of the shop that told me to replace it... and on top of that I boosted my car this morning and reversed the polarity by accident and created a small spark and now my ABs ASR light is on and my speedometer doesnt work

Any Thoughts or help from you guys would be kindly Appreciated

Thanks in Advance

George
