[W126 Coupe] Help-Easter Sunday- I am stuck in library Parking Lot with 89 560 SEC

[Dick Spellman]

Hi Jack:

Possibly the fuel pump relay as well.  Very simple to test.  Bring a 
short piece of wire, 2 inches or so and trim the ends.  Should be lamp 
cord gauge such as 18 or 16 ga wire.  Make a horse shoe shape so that 
you can jumper across the two terminals in the fuel pump relay socket.

Steps would be pull (un-plug) the relay, then place the jumper across 
terminals n and n.  Try and start the car normally with no foot on the 
gas.  If it works, drive the beast home and order a new relay.  If it 
does not replace the relay and move on to other suggestions.

Good luck,  Dick
On your 89 SEC the relay should be located at or near N16/3 as seen in 
the service manual photo below.  The two sockets you need to jumper are 
directly opposite each other.  I do not know your socket configuration 
so someone else will need to chime in.
