Usally they have a fuel gauge tester. They hook it up and it sends ohms for e or 1/4-1/2-3/4 and full. The pump my not be alined properly because you buy the pump seperately from the sending unit. Then they go togeather to be installed. Before taking anything apart find a shop with a fuel gauge tester with the sending unit and the float is sticking.

This sounds like it could be one of two things.

1) Damaged fuel tank sending unit connectors can be serviced by splicing in a new wire harness connector. The new connector can be obtained by ordering the fuel tank sending unit wire harness and cutting off the connector.

ACTION: Splice the new fuel tank sending unit connector to the existing wire harness.
Refer to the following procedure for service details.

2)The electronic instrument cluster (ETC) fuel gauge may intermittently show an increase in the fuel level or display circuit open †CO. This happens when the fuel tank level is above 12 full. The condition is caused by either an intermittent high resistance contact or an open circuit internal to the fuel sender unit.

ACTION: May need to replace fuel sender assembly.

Let me know if you need more instructions.

The Data Communications Link (DCL) is a wiring system that allows the sharing of information between the Electronic Engine Control System (EEC- IV), the Message Center Control Assembly (MCCA) and the Cluster Control Assembly (CCA) located in the electronic instrument cluster panel by using a common link (DCL).

The EEC-IV system transmits the following information through the DCL to the CCA and MCCA:

Engine rpm.
Engine coolant temperature.
EEC-IV malfunction indication.
Fuel used.
The CCA transmits the following information through the DCL to the MCCA:

Fuel level.
Odometer.
Speed pulses.
Cluster display temperature.
Battery voltage warning.
Oil pressure warning.
English/Metric mode.
Vehicle in Accessory/Run (ACC/RUN) mode.
Engine temperature warning.
Charging system warning.
There are two EEC-IV, DCL strategies. One covers the 49-state application, the other covers California. The California strategy uses the EEC-IV system to transmit Malfunction Indicator Lamp (MIL) information to the MCCA. The MCCA uses MIL information to generate a CHECK ENGINE warning in the event of an engine sensor failure.

In the event of a DCL failure, an alternating message of CHECK ENGINE then CHECK DCL is displayed on the MCCA.

Always check the fuses and relays first. If those check out, then check all the wiring and connectors. With a vehicle this old, it isn't uncommon to find wires that have frayed/broken/burned, and/or connectors that've worked their way loose.

If everything checks out, then suspect the computer. But don't just replace it. Check the input/output wires to see if the computer is actually accepting inputs and giving outputs according to spec. If not, then the computer is bad.

Welcome to 2CarPros.

The CO indicates Circuit Open. There was a technical service bulletin put out years ago regarding this issue, and it was related to several Ford Motor Co vehicles.

Here is the TSB. Take a look through it. I feel confident it is relevant in this situation.

ISSUE:
There may be erratic Distance-To-Empty (DTE) and fuel gauge readings, or circuit open "CO" displayed in the electronic cluster with two (2) top/bottom bars highlighted. This is caused by fuel sender card overprint material and/or an intermittent connection between the spring and contact on the sender card.

Welcome back:

Yes, the tank needs removed. Here are the directions:

1987 Lincoln Continental V8-302 5.0L
Removal and Installation
Vehicle Powertrain Management Fuel Delivery and Air Induction Fuel Pump Service and Repair Procedures Removal and Installation
REMOVAL AND INSTALLATION
WARNING: Do not smoke, carry lighted tobacco or open flame of any type when working on or near any fuel related component. Highly flammable mixtures are always present and may be ignited, resulting in possible personal injury.

CAUTION: Fuel supply lines will remain pressurized for long periods of time after engine shut down. This pressure must be relieved before servicing of the fuel system is begun. A valve is provided on the throttle body for this purpose. Remove the air cleaner and relieve system pressure by using Rotunda pressure gauge tool T80L-9974-A or equivalent and drain the system through the drain tube.

Removal
1. Place vehicle on hoist-Do not raise.
2. Depressurize fuel system as previously described.
3. Remove fuel from fuel tank by pumping out through filler. Use care to prevent combustion from fuel spillage.
4. Raise vehicle on hoist.
5. Disconnect supply line and return line fittings and vent line at the right and left hand side rear axle frame kick-ups.
6. Disconnect electrical connector forward of tank.
7. Disconnect and remove fuel filler tube.
8. Remove fuel tank support straps and remove fuel tank to bench.
9. Remove any dirt that has accumulated around the fuel pump attaching flange so that it will not enter the tank during removal and installation.
10. Disconnect the supply line and return line fittings and the electrical connector.
11. Turn the fuel pump locking ring counterclockwise with the tool and remove locking ring.
12. Remove fuel pump and bracket assembly.
13. Remove seal gasket and discard.

Installation

1. Clean the fuel pump mounting flange and the fuel tank mounting surface and seal ring groove.
2. Put a light coating of heavy grease (Cl AZ-i 9590- B or equivalent) on a new seal ring to hold it in place during assembly and install in fuel ring groove.
3. Install fuel pump and bracket assembly carefully to insure that filter is not damaged. Be sure that locating keys are in keyways and seal ring remains in groove.
4. Hold pump assembly in place and install locking ring finger tight being sure that all locking tabs are under tank lock ring tabs.
5. Secure the fuel pump unit with the locking ring by rotating clockwise with tool until ring stops against stops.
6. Install electrical connector.
7. Lubricate fittings and install fuel line fittings and tighten to 13-20 Nm (10-15 lb-ft).
8. Install tank in vehicle, and tighten straps.
9. Connect electrical connections to fuel sender and fuel pump wiring harness.
10. Lower vehicle.
11. Install filler tube and attaching screws.
12. Connect vent line.
13. Lube fittings on right and left side of vehicle at kickup with light oil. Install fitting finger tight, then tighten 1/4 turn more.
14. Install a minimum of 38 liters (10 gallons) of fuel and check for leaks.
15. Install pressure gauge Tool T8OL-9974-A or equivalent on the fuel charging assembly fuel diagnostic valve and turn ignition key to On position for 3 seconds. Turn ignition key Oft and back On for 3 seconds repeatedly (5 to 10 times) until pressure gauge shows at least 241 kPa (35 psi). Check for leaks at fittings.
16. Remove pressure gauge, start engine, and recheck for leaks.

I checked 1986 and 1988 for location thinking it may have been a mid year production change, and nothing. The 1986 is the same and 1988 changed to an integrated module with the body style and engine change.

Have you checked under the hood in the power distribution box? Also, check to see if there is an EEC relay under the hood in the relay/fuse box and switch it with another relay with the same part number.

Let me know what you find.
