Fuel relay

i have a 1988 Mercedes Benz 260E where is the fuel pump relay and where is the wires loctated

See if you have a plastic shield behind your battery, bellow the windshield, it is under that. Please read attachment for some more info…

thinks for the information

when the car warms up it dies and it will start back up and then it wont start the next day and the fuel pump is good and the relay and fuse is good could the crankshaft position sensor have something to do with this.

How can you check the fuel pump on this system?

and the pressure?
