The following are instructions for removing the fuel pump resistor from its original mounting location on the lower right front body rail as shown in Figure 1, and replacing it with a new fuel pump resistor and cover in new location shown in Figure 2. The new location is on the front of dash sheet metal (3) at the rear of the engine compartment, inboard or to the left of the alternator (4). The passenger or right side windshield wiper arm (5) and stop (6) are called out for reference purposed only. 1. Turn the steering wheel to the full right position. 2. Open the hood and disconnect the negative battery cable. 3. Remove the diagonal brace (1) from over the windshield washer solvent reservoir by removing the two bolts (2) that attach it to the radiator support and the one bolt (3) that attaches it to the strut tower. Refer to Figure 3 4. Remove the two plastic push-in retainers (1) that attach the windshield washer solvent reservoir (2) to the radiator support (3) and the one nut (4) that attaches it to the strut tower (5). Refer to Figure 4. 5. Reposition the reservoir for access to the area rearward of the battery. 6. Raise the vehicle on a hoist. 7. At the right front wheel opening, remove the three screws that attach the inner fender splash shield to the front fascia at the wheel opening and the two screws that attach it to the bottom of the fascia. Refer to Figure 5. 8. Reposition the inner fender splash shield (1) to access the fuel pump resistor (2). Refer to Figure 1 at the beginning of this procedure. 9.

Fuel pump relay is located in the front of the trunk. Turn ignition switch to START position. If engine starts, go to next step. If engine does not start, go to FUEL PUMP RESISTOR (3.5RL) . 2. Turn engine off and ignition on. Measure voltage between ground and PCM 12-pin connector terminal No. 4 (Green wire). If battery voltage is present, go to next step. If battery voltage is not present, go to step 4). 3. Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral, until radiator fan comes on. Allow engine to idle for at least one minute. Turn engine off. Disconnect vacuum hose No. 21 from vacuum manifold. Apply 8-12 in. Hg (27-40 kPa) vacuum to Manifold Absolute Pressure (MAP) sensor. Start engine and run at 6500 RPM with no loads and transmission in Park or Neutral. Measure voltage between ground and PCM 12-pin connector terminal No. 4 (Green wire). If less than one volt is present, fuel pump relay circuit is okay. If one volt or more is present, substitute a known good PCM, then recheck. If symptom or indication goes away, replace original PCM. 4. Turn ignition off. Disconnect PCM 26-pin and 12-pin connectors. Disconnect fuel pump relay 4-pin connector. Using a fused jumper wire, connect fuel pump relay connector terminals No. 2 (Red/White wire) and No. 4 (Green wire). Turn ignition on. Measure voltage between ground and PCM 12-pin connector terminal No. 4 (Green wire). If battery voltage is not present, go to next step. If battery voltage is present, replace fuel pump relay. 5. Remove jumper wire. Measure voltage between ground and fuel pump relay 4-pin connector terminal No. 2 (Red/White wire). If battery voltage is present, repair open or short in Green wire between PCM and fuel pump relay. If battery voltage is not present, repair open in Red/White wire between fuel pump relay and FUEL PUMP fuse No. 22 (20-amp), located in underdash fuse/relay box. FUEL PUMP RESISTOR (3.5RL) 1. Fuel pump resistor is located in the left corner of the trunk. Disconnect fuel pump resistor 2-pin connector.

FWD Notes Removing And Installing Fuel Pump CAUTION: To remove the Fuel Pump (FP), the fuel tank may only be filled to a maximum of 3/4. Empty fuel tank if necessary. Recommended special tools and equipment 3087 wrench for tank sensor VAS5190 fuel siphoning device Empty fuel tank Observe safety precautions. Observe rules for cleanliness. CAUTION: Observe safety precautions when disconnecting the battery. Disconnect battery Ground (GND) strap with the ignition switched off. CAUTION: Secure Ground (GND) wire of VAS5190 to a blank portion of the chassis. Pull cone piece -2- from shaft piece -1- of VAS 5190. Using insulating tape, apply a mark -arrow- on hose at length a = 1465 mm from end of suction hose. Remove fuel filler cap from fuel filler tube Screw shaft piece -1- of VAS 5190 fuel siphoning device on to fuel filler tube of fuel tank . Now slide suction hose as far into fuel tank until the mark applied earlier -arrow- stands on shaft piece. NOTE: If using a siphoning device without shaft piece, proceed principally in the same manner In this case, apply a mark -arrow- on hose at length a = 1400 mm from end of suction hose using insulating tape. The suction hose is inserted correctly when the marking applied earlier stands opposite the lip of fuel filler tube. If the hose can only be inserted with difficulty, smear it thinly with engine oil. Never use lubricants containing silicon. Drain fuel tank through fuel filler tube. Carefully remove siphoning hose. Removing Sedan: Remove luggage compartment lining. Push forward the right backrest of rear seat, if necessary. Avant: Remove left 1/3 backrest. Remove left side trim in luggage compartment and dirt tray. All: Remove cover for connector flange (arrows). Release and disconnect harness connector -1-. Disengage electrical harness connector -2- and lay it aside. CAUTION: Work on the fuel system must only be performed when engine is cold. Fuel system is under pressure. Before opening system, place rags around the connection area. Then release pressure by carefully loosening connection Mark and disconnect fuel supply line -1- and fuel return line -3- (press release tab). Disconnect ventilation line -2- (press release button).
