If you're the type to let your car perennially run on or near empty, you will likely run completely out of gas at some point. In many cases, the long walk to the gas station is the hardest part of this embarrassing situation, but sometimes you could also have a difficult time restarting the car even after you put more gas in the tank.obd2 scanner
1. Replenish the tank with a minimum of two gallons of gas to get you to the next gas station. Place the gas cap back on before you attempt to restart the car.
2. Pump the gas pedal a few times to help get the new gas moving through the system.
3. Turn the key to the "on" position to prime the fuel injectors if your vehicle has a fuel injection system (skip this step if it does not). Wait a few minutes.
4. Turn the key all the way to restart the car. You may have to hold the key in place for a few seconds before the car turns over.
5. Wait a few minutes and then repeat the process if the car does not restart after the first attempt. If after five attempts the car does not restart, allow the car to sit for at least an hour before trying again.
6. Tow the car to a trusted repair shop if after an hour it still does not restart.

How to diagnostic Airbag Codes for a BMW X5
For automakers, safety is a priority, and according to the Insurance Institute for Highway Safety, airbags significantly increase automobile safety. Every new car, including the BMW X5, comes with airbags. If your airbag warning light comes on, or you think there is something wrong, you can check them by plugging in an airbag scanner tool. The tool will give you a numeric code that corresponds to a specific airbag or seatbelt malfunction in your car.
Fault Code 2
Both airbags and seatbelts are considered part of your BMW X5's Supplemental Restraint System, so some of the codes your scanner tool prints out may deal exclusively with seatbelt problems. Others, like fault code 2, relate to the airbags. If the scanner gives you fault code 2, it means that the driver's side airbag ignition circuit is defective. This code will sometimes be tripped when other parts, such as the steering wheel, are repaired, so a qualified person will need to check the circuit wires to verify the problem.
Fault Code 5
If this code comes up, it means that the airbag ignition circuit on the passenger side is defective. As with fault code 2, your BMW X5's circuit connections and wires will need to be checked. This should always be done by a professional or an experienced person to avoid injuries or damage to the vehicle.
Fault Code 19
Sometimes your warning light will not go off, or it fails to come on when you are sure there is a problem. If you check your SRS system and see fault code 19, it means that you may have a faulty warning lamp. Check your light by turning your BMW X5 key to ignition-lock position 1. If the lamp lights and goes out after a few seconds, it is not faulty. If the lamp stays lit, you may need to code your airbag control unit.
Fault Code 73
Getting this fault code when scanning your BMW X5 means that your airbag squib wires may have short-circuited. The circuit wires to specific numbered pins -- 1, 2, 3, 4, 10, 11, 13 and 14 -- should be checked for short circuits among themselves. As always, mechanical work involving electrical circuits should be done only by an experienced person or qualified professional.

Ways to Increase Fuel Mileage on a 4.3L Vortec
The Chevrolet 4.3 V-6 engine used in a number of trucks and vans throughout the 1980s and 1990s. Among the larger V-6 engines produced, the fuel economy often suffered in exchange for impressive torque and horsepower. Making these engines more efficient is simply a matter of adding a few bolt-on accessories, though it is unrealistic to expect the fuel economy of four-cylinder engines or hybrids.
Air Intake Upgrade digimaster 3
The first and most obvious way to improve the fuel economy of your 4.3 V-6 engine is by improving the quality of the air that the engine consumes. This can be done by adding one of two products, both widely available at any local auto parts store. The first is a simple high-flow air filter, which installs in place of the stock paper filter; the second is the replacement of the entire intake track with a cold-air induction kit. Both improve fuel economy, though the cold-air induction kit does so significantly more than the basic high-flow air filter, as is reflected in the price disparity between the two parts. Expect to pay upward of $300 for a cold air induction kit, and less than $50 for a high-flow air filter (as of 2011).
Exhaust Upgrade
The installation of a catalytic converter-back exhaust system works best when installed in tandem with a cold air induction kit. By limiting the restriction of air within the engine, the engine is made more efficient. As a by-product, you will also notice a significant improvement in the throttle response and power of the truck or van. Under normal driving conditions, the additional 20 or so horsepower gained with the modification will translate into at least 1 to 2 additional mpg in fuel economy.
Throttle Body Spacers Creator C110
Throttle body spacers, when used by themselves, have a negligible effect on the power and fuel economy of the 4.3L engine. However, when used in conjunction with modifications, can significantly improve fuel economy. They do this by increasing the volume of air taken into the intake manifold, as well as spinning the air to help further atomize the fuel-air mixture. The throttle body spacer by itself may only add 1/4 to 1/2 mpg in fuel economy, but used with the exhaust and air intake upgrade, can improve fuel economy by as much as 1 to 2 mpg, in addition to gains realized by the intake and exhaust upgrade.
Computer Programmers
Engine management computers are designed to work with a broad range of variables. Taken into account is the lowest possible octane rating of fuel available nationwide, which is generally 87 octane, as well as a broad spectrum of air densities to account for the different elevations in which the vehicle is likely to be operated. Using a computer programmer allows you to fine-tune the engine of the vehicle to the exact specifications of the area in which the truck or van is usually driven, as well as your preferred octane fuel. Using a computer programmer can increase fuel efficiency by 2 to 4 mpg, depending on driving conditions and your driving habits.

How to diagnose the BMW Head Gasket?
Despite the fact that BMWs Creator C110 are among the best engineered cars in the world and the company is a leader in many aspects of the automotive industry, many of the cars it produces can suffer from head gasket problems. This is caused by a few factors, namely the fact that BMWs often appear to have water pumps, thermostats and radiators that don't last long. There are some things that can be done to prevent a warped head gasket as well as signs to look for if you think you have a problem with the head gasket.
Causes
A failed head gasket is generally cause by an overheating engine that, in turn, causes the head to warp. If the head warps, the head gasket cannot properly seal the head to the block, allowing coolant to mix with the oil inside the motor. An engine will overheat for a variety of reasons. If the water pump fails on a BMW, it will stop circulating coolant from the radiator into the motor, causing potential overheating if the problem is not caught in time. If the thermostat fails, then the fan will not turn on and cause overheating. The least likely possibility is a failed radiator core, though this does happen as well.
Identification obd2 scanner
There are several signs that a BMW has a blown head gasket, such as if the temperature gauge shows the car is routinely running hot. If the low coolant light comes on, even after topping up the coolant, it's leaking somewhere. Another way to tell is by opening up the engine's oil cap and inspecting the oil. If the head gasket is blown, the oil will mix with the coolant and the oil will have a brown, milky appearance. If white smoke comes out of the tailpipe even after the car is warmed, there is a good chance there is a problem.
Prevention/Solution
There are several things you can to help ensure your BMW motor does not suffer from a blown head gasket. It is recommended you change the water pump every 60,000 miles or so and replace the thermostat if there is any sign of the motor running hot. Though radiators are expensive, it's a good idea to replace them every 100,000 miles or so. It is also possible to upgrade to an aluminum radiator on most cars as well as a better engineered aftermarket water pump. It's also a good idea to periodically have the coolant flushed and replaced.
What Happens if the Head Gasket Is bad?
If the head gasket blows on a BMW, fixing it is labor intensive. The head gasket itself is usually a $200 part, but removing the head takes many hours. Most shops charge around $1500 to properly fix a head gasket.
