No fuel to engine 1994 f150 4.9 mfi automatic 2wd 2 door single rear after axle gas tank. New fuel pump sending unit & new fuel filter. All fuses under dash good & all fuses & relays under hood good. No fuel coming to engine!? Complete 100% tuneup & ALL fluids changed & flushed & new filters all around. Battery,alternator,starter relay & starter good. If the fuel pump relay is working then current is running to the fuel pump? There is no sound coming from the new fuel pump. When I unhooked the fuel filter hose coming from the engine to the fuel filter there is no fuel coming out of the fuel filter!? If the new fuel pump is not sending fuel to the engine does that mean I have a defective fuel pump or something else? Also the gas gauge is not working either. GOD bless & thanks for any help.

The fuel pump is located inside the fuel tank so you must first remove tank from car. After removing locate the wires going into tank. There is a large metal ring around wires. Remove ring by turning counter clockwise, then lift unit out of fuel tank. The pump is mounted in rubber at the end of fuel lines.

This is a common problem and to correct this problem will require the replacement of the fuel sending unit. The fuel sending unit is inside the fuel tank and has the fuel pump mounted in it. This requires the removal of the gas tank and then the fuel sending unit can be removed from the tank.

REMOVAL AND INSTALLATION Fig. 1: Fuel pump unit

1. Disconnect the negative battery cable.
2. Relieve fuel system pressure.
3. Remove fuel filler cap to release fuel tank vapors. Leave cap off until repairs are completed. Gasoline fuel vapors are extremely flammable. Ensure that fuel is stored in a container that can be properly sealed. Never store fuel in an open container. Store container in a safe place away from heat.
4. Remove fuel tank by performing the following:
   1. Step 1: Drain fuel from the tank into an approved container for storage.
   2. Step 2: Raise and safely support the vehicle.
   3. Step 3: Remove rear stabilizer bar at links, pivot bar downward.
   4. Step 4: Remove hoses and pipes from tank unit.
   5. Step 5: Remove hoses at tank from filler and vent pipe.
   6. Step 6: Disconnect tank unit harness from rear body harness.
   7. Step 7: Support fuel tank and disconnect 2 fuel tank retaining straps.
   8. Step 8: Remove tank from vehicle.
5. Remove sending unit, gasket and pump assembly by turning cam lock ring counterclockwise. Lift assembly from fuel tank and remove fuel pump from fuel tank sending unit.
6. Pull fuel pump up into attaching hose while pulling outward away from bottom support. Take care to prevent damage to rubber insulator and strainer during removal. After pump assembly is clear of bottom support, pull pump assembly out of rubber connector for removal. To install:
   
7. Push fuel pump assembly into attaching hose.
8. Install fuel tank sending unit and pump assembly into tank assembly. Use new O-ring seal during reassembly.
9. Install cam lock over assembly and lock by turning clockwise.
10. Support tank and position in vehicle. Install tank straps and secure with retaining bolts. Tighten to 25 ft. lbs. (33 Nm).
11. Connect tank unit harness to body harness.
12. Connect hoses to filler and vent pipes. Tighten clamps.
13. Connect hoses and pipes to tank unit.
14. Connect rear stabilizer bar to links. Tighten bolts to 42 ft. lbs. (58 Nm).
15. Lower vehicle.
16. Refill tank and install filler cap.
17. Connect negative battery cable.
18. Start engine and check for leaks.

Relieve the fuel pressure at the pump switch located in the passenger compartment under the carpet of the transmission hump on the passenger side. Remove the fuel tank. Turn the lock ring counterclockwise until it's loose and remove the lock ring. Pull the fuel pump/sending unit from the tank being careful not to bend the arm for the sending unit float. Discard the old lock ring seal. Installation is reverse of removal with the following additions: (a)Apply a coat of heavy grease to the new lock ring seal to hold it in place during assembly. Install the seal in the lock ring groove. (b)Install the fuel sender/pump unit into the fuel tank so that the tabs of the unit are positioned into the slots in the fuel tank. Make sure to keep the seal in place during installation until the lock ring has been tightened properly. (c)Hold the fuel sender/pump unit in place, install and tighten the locking ring clockwise until the stop is against the retainer ring tab. - Mazda Pickups Repair Manual
