my 420sel suddely loses power
 

it has 115k,good shape,just got it.sudden loss of power.first time i coasted to a stop and it started right up ran fine.second time loss of power,i banged on fuel pump relay and it started and continued to run till i got home.it starts up fine runs fine so i dont think fuel pump,but relay may be bad.does this make sense,especially as i banged on relay and car resumed working.ive ordered a relay,but old one is tight in there,any hints on getting it out

yes they can stick when they get old.I would replace it,buy two and carry a spare,cause EURO parts makes them now.

relay should just pull out?or is there another way to get it out?

got it out,thanks
