Question about 1984 Mercedes-Benz 190
Have had the fuel pump relay replaced (Could this burn out in two weeks?)
It starts but then drives for 30 secs (or it could be ten minutes or twenty minutes) and cuts out when driving say 20 - 25 miles per hour.
When I try to restart it starts ok but the rev counter drops immediately and it cuts out. This can happen 15 times before the start will be maintained and then it can happen slowing for a traffic light five
My mechanic is stumped. Lizzie in London
You could have a defective fuel pump, when they go bad they can draw enough current to fry the relay contacts, so I would suggest you test how many amps the fuel pump is drawing, I have fixed this very issue of repeated relay replacements, it was always the pump was shot.
