I have now gone thru 2 fuel pump relays on my 99 ml 430 , 160K,
The dealership wants $130 to dinog. but from what I am reading the wiring problem seems to be the issue.
My ml will not start in the morning due to the power draw all nite...which drains the battery. So I pull the relay and the car starts. This is getting old real fast.
what is the cheapest way to fix this issue. I can imagine I have the only ml with this problem and the dealership should know this is a problem.

The 20amp fuse is warped alittle but not blown , which is next to the Fuel pump relay. The relay is very warm to the touch when pulled.

The vehicle performs ok when driving.

fuel guage , when vehicle is sitting in a slight angle in my driveway will NOT show correct fuel level. I have to turn the vehicle off at a light and then restart to bring level up to correct postion. This is an intermediate problem.

Thanks
