It's behind the dash, on the passenger side. Open your glovebox, squeeze the tabs on either side in, and let it hang straight down. It's a bit difficult to reach, but if you're nimble and limber you can.

If it's not a relay, it might be a bad ground...

ThunderbirdSport302 Thanks, Now a question.

At the fuel pump relay:
The yellow wire should always have 12 volts.
The red wire should have 12 volts with the ignition switch on.
The pink/black wire should have 12 volts when the relay is picked.

The electronic control provides the ground to pick the relay, but it only picks it for 2 seconds when you turn the ignition switch to run.
To keep the relay picked continuously so you can trouble shoot, ground the fuel pump test pin at the self test connector.

I can ask the location of the self diagnosis connector

The self test connector is in the vicinity of the windshield washer reservoir.

Here is a pic of it http://img.photobucket.com/albums/v648/Loaded87IROC/001-20.jpg

friends, I need know where is located the "ECC POWER RELAY TERMINAL5"

follow the flow of wires from the relay fuel pump under the carpet till the ECU.
check the ground connections and test voltage.

hello friends, on this occasion I can tell you that after testing the car and found the problem.

the injectors do not work, and the fuel pump. I think this is deve problems in the electric system. (ECC POWER RELAY)

you have had similar problems.

this information will be grateful lot.

Hello, good day

Friends, I can tell I've done some testing to Cougar. specifically to the fuel system (ECC Power Relay, Fuel Pump Relay, Inertya Swich and fuel pump.)

When testing the fuel pump independently, I found that this was defective and was replaced by a new one.

The relay swich are good and the inertia works.
But here's the problem. Only reach 5 volts to the fuel pump and it needs 12 to run.

The ignition module works, but not the injectors.

The yellow board "check" will not start.

Are any of you can guide me?
I think it can be a ground resistance or burned off.

any of you can tell me how to test the bridge connector on the self test?

Many thanks

Pablo.

Yesterday I make a KOEO test at my mercury cougar, and this are the result:
15-code: EEC permanent Read Only Memory (ROM) test failed. and / or battery powered EEC Keep Alive Memory (KAM) test failed.

I Decided today to test the voltage and ground conenector ECU Pin Outs "ECC-IV EFI-TC," And This are the result:

•
EEC-IV Wiring Information

Pin No

1    OK   Keep Alive Power   Battery +12V
9    OK   Mass Airflow Sensor Ground   0 Volts
16    OK   Ground   0V
20    OK   Case Ground   0V
22    OK   Fuel Pump Relay   +12V Ignition On, 0V Engine Running
37    OK   Ignition Power   12V with Ignition On
40    OK   Ground   0Volts
49    OK   HEGO Ground   0Volts
57    OK   Ignition Power   0Volts Off, 12V Ignition On
60    OK   Ground   0Volts

if you have similar experience or have the technical information needed to "life on" the mercury.
appreciate your words.

and with kind regard to all you.

cuogar diagnosis "SD10 ECC IV" => not work.

I buy a mercury sable SD9 ECC IV and not work. but close the fuel system.

Engine 232''stays in the car ... but a controlled is changed.

My idea is to buy and build a mega squirt (ECU programmable)
this megasqirt control (injection, distribution, feeding and other qualities.)

if you gone through something similar or know the problem will thank you a lot.

ciao

is a risk and an interesting project.

the keep alive memory, code 15 will set after the battery has been disconnected, if it's there and battery has remained connected there is a wiring issue or problem in the EEC... I've never seen a code 15 prevent engine from running...

You mentioned mass air, there is no mass air on a 3.8 through 1988...

If the fuel pump pin on the EEC test plug is grounded the pump should run, if not you have a relay, wiring or maybe fuse link problem...

Does the car have spark from the coil??? If not it has no iginition pulse and the EEC will not activate the fuel pump relay...

the mercury have spark from the coil.

the fuel system in the plug and was positive.

I used snips to make an access pannel in my trunk so my fuel pump can be swapped in 10 minutes without removing the tank. Works great. I was able to change the pump in the parkinkg lot at work one time when it went bad, with minimal tools.

Forgive my irrelevant post ^^^. I'm posting from my phone and didn't see the other two pages where the pump was already changed.

is not at all unrelevant. is interezante operation. but would rather put a gas tank fuel pump independently.

ECC-IV definitely is defective

Thank for your help's
