Q: Ignition key not working - 1987 Mercedes-Benz 420SEL

A certified technician from YourMechanic can replace your battery (https://www.yourmechanic.com/services/battery-replacement) at your home or office and get you on your...
Q: Car will only start after being jumped - 1991 Mercedes-Benz 420SEL
Answered by David
If this is a fuel issue, it's likely the check-valve in the fuel pressure regulator not holding pressure during shutdown. This valve keeps a low pressure in the fuel injection system for faster starts. If faulty, the fuel pump has...
Q: Car running sluggish then dies - 1988 Mercedes-Benz 420SEL

Trusted by thousands of happy car owners



Very impressed with the quality of work. Ned was on time and on budget. There were no surprise extra costs. Ned even helped me out with my other car, even though I didn't have an appointment for the other car. He took care of all of my car problems and he even found me a coupon for an oil change. I will be using this service again.



I have to say I am totally satisfied with the service performance and Bernard is quite professional offering details of the work which was completed. I will definitely utilize your service in the future and will recommend to family and friends.



Ben was great. He arrived early, completed the work quickly & cleanly, and was quite amiable. I didn't have to leave my home and got the maintenance completely with ease - 5 stars.
