On the firewall behind a plastic cover. This relay was defective and had a tech bulletin in the past.

The fuel pump relay is located on the passenger side in the engine compartment.

switch it with a relay that works, like your horn relay or simulate the relay with fused jumper with 12 volts from your battery. 87 on your relay is your out to the fuel pump. putting 12 volts to the point of contact where 87 would be should start your fuel pump.

The EEC Power and fuel pump relays are behind the computer on the passenger side under the dash. The relay on the blower bracket is the fuel pump.

The 1987 Honda Accord fuel relay switch is attached to the fuel injector pump. The fuel injector pump can be located on the top of the engine near the back.

the fuel pump relay should be on the pass. side inner fender there should also be a in-line fuse there too.if your fuel pump is not working,check the fuse and your grounds too.

it is located on the firewall on the passenger side

I have an 87 4runner and i had a similar problem turns out that the starter relay sends power to the fuel pump you might want to try replacing that relay

For testing purposes only you can jump the fuel pump relay (#30 and #87).

on a Mazda 626 there is a fuel pump relay check to see if you have a power signal from the relay to the pump, if so make sure there is power to the pump.

Fuel pump relay is located under the hood on passenger side bolted to the firewall a few inches below the windshield. It is black and has wires going into it.

You can swap it with another one. Many of the other relays have the same part number. Being a GM, the fuel pump is probably at fault, it is seldom the relay.

I have read that on an 87 GT its under the driver seat.

If you have a 4 pin relay marked in clockwise rotation as 87-85-30-86 jump the terminal sockets corresponding to 30 and 87.For a complete understanding of how relays work, view the first 4 videos on this site.

Fuel Pump relay on my 87' Camaro 305 TPI is located underhood on the right side of the firewall, its the second relay of the 3 or 4 in a row

you need to check the icm in the distributor it has the power to the fuel pump that goes through it on start up. As long as the relay and fuses are good.

connect 30 and 87 jumper wire if pump kicks on then it's your your standing on the driver side of vehicle it's the relay towards the front bumper (5 prong)...

The fuel relay often goes bad on these and shuts off the fuel pump and the spark. The relay is found in the black box in the right rear tire well.

The electric fuel pump is in the gas tank.

Fuel pump started making lower sounding noise when priming and wouldn't prime after a while. Let is set over night and it primed once and ran it for an hour, but didn't prime the rest of the day. Did this same thing for 3 days, but now it never primes. Checked fuses and swapped relays and tried to jump pin 87 to 30 and still would not prime. Testing the fuel pump relay socket I get strange readings on pin 87, which I believe is the input pin from the battery, pin 30 is output. When I tested the AC relay socket I get 12V on pin 87, but get strange readings like 25V sometimes more on pin 87 on the fuel pump relay socket. I know what a job it is the replace the in-tank fuel pump, I replaced it 4 years ago. This time it has a full tank of gas. I'm almost sure the fuel pump has gone bad but want to fix the cause of the problem this time. I don't want to ruin another fuel pump and these readings are worrying me. Any ideas?

there is no shut off switch on a 87 prelude. If you are having fuel delivery problems check fuel pump relay, fuel pump and both fuel shutoff solenoid valves on carbs if prelude is carb and not fuel injected
