I have a BMW 318d Tourer, when driving the car tells me doors are open but they are not also when stationary lights are flickering.


check your engine ground. also check for body ground as most computerized vehicles complete the circuits by grounding them. no ground or poor ground will cause the symptoms. could be as simple as cleaning battery terminals

I have a bmw e30 325i it cranks but will not start so what can I do to fix it?


Fuel Pump - can you here the pump (usually under the right hand back seat) running with ignition on?
Fuel Delivery (injectors) - squirt some fuel (just a cap full) into the manifold.
Spark - pull a lead off a spark plug and use a spare spark plug resting on the exhaust manifold.
Crank sensor - Injectors won't inject fuel if the ECU thinks the engine isn't turning. Crank sensor is at the front right lower side and as it gets older, the wire gets brittle and breaks most of the time where it meets the hard end. The connector is under the throttle body and should read 500-600 ohms.

How do I change a fuel pump for a 1997 Toyota corolla?


Late 90's Japanese fuel pumps are generally within the fuel tank. If you first locate the fuel tank and then see if there is an access panel above the tank, within the vehicle's body. If there is, then you can likely remove the panel and then pump assembly from the fuel tank. ALWAYS DISCONNECT THE VEHICLE'S BATTERY WHEN WORKING ON THE FUEL SYSTEM.

If you have no access panel, then you must remove the tank. In order to do that, you will first need to drain the system to relieve weight from the tank. Disconnect the filler pipe and any short breather pipes and fuel pipes.
Then disconnect the tank straps or fixing bolts and gently lower the tank, making sure not to snag or pull on any connecting pipes or wires which may be less visible.
With the tank lowered you will find the location screws or pump location ring on the top. Remove those as carefully as you can. Do not use any method which may create sparks.
Once you have your pump removed, then re-assembly is much the same as disassembly, but in reverse. I would recommend also replacing the rubber gasket on the fuel pump mounting plate as a matter of precaution.

My digital gas gage reads full all the time I have to go by my miles and sometimes that don't work and I run out of gas..how do I fix my problem


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 8470h037.gif
  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).

How do i take my fuel pump out in my bmw 325, i got the rear seat put and the cover on the passenger seat off, i just cant get the pump out


The fuel pump in your 325 is under the rear seat, passenger side. Take the seat out, then pull up the rubber grommet with the wire going through it. Leave the wire alone for now. Peel up the thin rubber insulating mat. It is pre cut by the factory and not glued down. Remove the four nuts (10mm socket) and lift the round plate. Now remove the wire by sliding the plastic plug type housing back and lift the entire plug type housing up. Now, remove the hose clamp and slide the hose back off the plastic tube. If you damage the clamp, buy a new 1/4" clamp at the auto store for .30cents. Now unscrew the steel ring holding the pump in place. Unscrew this ring by tapping the ring with a screw driver and hammer. Remember counterclockwise (off). Now put your finger in the plastic ring molded into the top of the pump and pull up with some force. It is in place with a rubber gasket. Tight, but it will come loose. Be careful not to drop any thing into the tank. On the other side (drivers side) is a float/sensor. When reinstalling, seat the rubber gasket into the hole then drop the new pump/sensor into place. Your tank is like a saddle bag so it has two float/sensors. Time: 25 minutes

How do know if your fuel pump is on the right or left? My Bmw is a 1999 323i sedan.


On something that new, the fuel pump will be electronic and will more than likely be located in the fuel tank. So to reach the pump you will have to drain and remove the fuel tank and it will be located near the center of the tank only accessible through the top of the tank by removing the 6-10 bolts that hold the pump and float assembly on the tank. Take care not to damage the gasket or the assembly.

I need to replace the fuel pump in my 1985 Chevy S10 pickup, need all help. What is the procedures?


EXACT PROCEDURE ! Please Rate Me Fairly for this!! Thank you And Good Luck !!


ELECTRIC PUMP

REMOVAL
  1. Before servicing the fuel pump the fuel system pressure must be relieved. See: Fuel Pressure Release
  2. Disconnect the negative battery cable.
  3. Raise the car on a hoist.
  4. Remove the fuel tank. See Fuel Tank / Service and Repair.
  5. Remove the fuel tank sending unit and pump assembly by turning the cam lock ring counterclockwise. Lift assembly from the fuel tank.
  6. Pull the fuel pump up into the attaching hose while pulling outward away from the bottom support. Take care to prevent damage to the rubber insulator and strainer during removal. After the pump assembly is clear of the bottom support, pull the pump assembly out of the rubber connector for removal. NOTE: Inspect the fuel pump attaching hose for any signs of deterioration. Also check the rubber sound insulator at the bottom of the pump. Replace damaged or deteriorated parts.
INSTALLATION
  1. Push the fuel pump assembly into the attaching hose.
  2. Position the fuel tank sending unit and pump assembly into the fuel tank. Use a new "O" ring seal. NOTE: Care should be taken not to fold over or twist the strainer when installing the sending unit as this will restrict the flow of fuel. Also, verify that the strainer does not block the full travel of the float arm.
  3. Install cam lock over the assembly and lock by turning clockwise.
  4. Reinstall fuel tank.
MECHANICAL PUMP

REMOVAL and INSTALLATION

NOTE: To ease pump installation, rotate the camshaft so the camshaft eccentric is out of the way of the fuel pump rocker arm.

  1. Disconnect fuel lines from fuel pump.
  2. Remove fuel pump mounting bolts and the fuel pump.
  3. Remove all gasket material from the pump and block gasket surfaces. Apply sealer to both sides of new gasket.
  4. Position gasket on pump flange and hold pump in position against its mounting surface. Make sure rocker arm is riding on camshaft eccentric.
  5. Press pump tight against its mounting. Install retaining screws and tighten them alternately.
  6. Connect fuel lines. Then operate engine and check for leaks.
