At the top of the forum page find the link "buy parts". Click on it and enter your car's year. Proceed as if you are going to order a fuel pump relay.
In the search bar, type in "relay". From the results, choose fuel pump relay. What you will get is pricing. But also a picture of your relay. Now find your fuse box next to the brake master cylinder. Open and look to the top left corner. For reference, too, the tall but square relay next to it is your wiper timer relay. Replace this if your wipers loose the intermittant feature. And the yellow relay nearby is the rear window defroster relay.
Have a great day.

Fuel pump relay and OVP relay missing in 86 420SEL

Owner had it hauled to the shop yesterday with the complaint that it would not crank and both fuel pumps have been changed out. He mentioned that he thought someone may have sabatoged it and looking around the fuel pump relay and the OVP relay is missing. Thankfully he has a parts car I'm going to go get the parts off of here in a little bit.
