Will not start

wont start sounds like it is out of gas has gas, also only codes are for evaporator sensor
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
The code related to the evaporative emissions control system relates to controlling the fumes in the fuel tank. When this is not working properly this can impact starting of the engine and the running condition of the motor. Your car has a small purge valve called a purge solenoid in the Evaporative Emissions system that controls the venting of fumes from the fuel tank as these fumes build up inside, particularly when you are refueling the car with gas. The EVAP system prevents fuel vapors from the fuel tank from escaping into the atmosphere. The EVAP system collects and temporarily stores the fuel vapors in the charcoal canister. The charcoal canister is filled with activated carbon pellets that can absorb the fuel vapors. When the engine is running, the fuel vapors are purged from the canister and burned in the engine. The vent control valve (solenoid) controls the flow of outside air in and out of the charcoal canister. The vent valve is controlled by the engine computer (PCM). Normally the vent valve is open. It closes when the engine computer tests the EVAP system for leaks. If a leak in the EVAP system is detected, the Check Engine light will illuminate on the dash and the trouble code related to the problem will be stored in the engine computer. When an air leak is present in the EVAP system, the MAP sensor will not be able to determine the air density, and the MAF sensor will not be able to determine the volume of air, entering the engine correctly. This will lead to an over fueling situation or an under fueling situation depending on the size of the air leak and engine operating speeds and load. This may eventually lead to catalytic converter problems as well as misfiring problems. I would recommend having an expert from Your Mechanic come to your location to diagnose and inspect your vehicle.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common reasons a Pontiac Vibe won`t start are a dead battery, an alternator problem, or failed starter.
The most common reasons a Pontiac Sunfire won`t start are a dead battery, an alternator problem, or failed starter.
This usually means the battery is bad and incapable of handling a huge request for power to crank the engine over. Headlights begin white and bright, when you try to start the engine, they dim to nothing or almost nothing then as soon as you let go of the key, the headlights QUICKLY bounce back to white and bright.
The most common reasons a Pontiac G6 won`t start are a dead battery, an alternator problem, or failed starter.
Blown Fuse

If there has been a surge, a fuse that controls the fuel pump, the fuel injectors, or another component that`s vital for your car`s functioning, it may be the cause of your car`s failure to start. Unlike most of the other problems, this is one that you can check yourself, if you want.

The most common reason cars don`t start is a dead or faulty battery. Even though most cars run on gasoline, they all require electrical power to function. The starter that cranks your engine to start requires an electrical signal to fire. If something`s wrong with your battery, your car engine won`t turn over.
The most common reasons a Pontiac G5 won`t start are a dead battery, an alternator problem, or failed starter.
Hard start symptoms and starter failure may NOT be caused by the starter, but could actually be caused by the crankshaft position sensor. If your vehicle is experiencing one or more of these symptoms, the crankshaft sensor may be at fault.
Why your car struggles to start but runs fine. There are a number of reasons why your car might be slow to start but runs as-normal once it gets going. Causes can vary from weather conditions to battery health, wiring issues, starter motor concerns and fuel-pump health.
Can you jump-start a car with a bad starter? Most of the time, NO, you can`t jumpstart a car with a bad starter unless you repair it. When the battery is dead, jumper wires or boosters are employed. You use a second battery to provide the necessary electricity to start the car.
Insert your ignition key and turn it to Accessory (or press the start button once without pushing the brake pedal). Press the Lock button on your remote car starter. Within five seconds of turning it on, turn your key back to the “off” position (or press the start button again).
The most common reasons a Pontiac Grand Prix won`t start are a dead battery, an alternator problem, or failed starter.
So can a bad starter drain your battery? The short answer is: Yes, it can. It could also drain the battery even faster if you repeatedly try to start your car with a faulty starter. A faulty starter is also one of the leading causes of battery overcharging.
Starters do wear out or fail over time. However, they usually have several warning signs that they`re on the way out, and mechanics may ask you about them if you take your vehicle into an auto repair shop. Your answers will help them diagnose the problem.
Pontiac Vibe Reported Problems: Oil leaks from the valve cover gasket are common. Replacing the valve cover gasket is not too expensive. Another common source of the oil leaks is the timing belt tensioner located in the drive belt area, at the back of the engine. Watch these videos to see how it looks.
Fuel pump failures tend to be sudden and unpredictable, with few symptoms to warn the motorist that trouble is brewing. And the higher the mileage on the vehicle, the greater the risk of a fuel pump failure.
Unfortunately, if the starter motor has completely gone there`s no way to get your car going again. However, when a vehicle doesn`t start, it`s typically to do with the battery`s insufficient voltage to start the motor.

Fuel pump engages. Batery good, alternator good volts, jump start helps when wont start. Temp does not matter. Intermittent?
ANSWER : Hello. Thank you for writing in. There are several reasons your vehicle may only start when jump starting. The first and most common is a build up of resistance that is causing you to need a boost of voltage to get the engine started. This may be due to poor battery cables, a bad ground connection, a poor starter solenoid, and a couple of other issues. The first thing you want to do is perform a visual inspection of the starting system. Make sure there is no corrosion build up in the battery cables. You can also check the resistance across these wires and make sure you have a solid connection between components. You then want to make sure the starter solenoid is doing its job. It is responsible for taking the small amount of electricity sent by the ignition and turning it into a huge electrical charge that is strong enough to push over the engine with the help of some gear ratios in its favor. Do some more testing, and stick to the basics before assuming its something seriously complicated.

Vehicle won’t start, once it’s jump started it only stays running until you turn it off, then it work start again without jumping.
ANSWER : Hi there. There could be two problems here. It is possible that your battery is bad and will not take a charge from your alternator while driving. In that case every time you shut your car off you will not have enough juice to start it again. Inspect your battery – it should have at least 12.5 to 13 volts to start your car, if it doesn’t you will need to replace the battery. The second problem could be that your alternator is bad and not charging your battery, in this case you will need to replace your alternator. Both the battery and the alternator can be tested in your car. If you would like to have the car checked for you, a certified professional from YourMechanic can come to your car’s location to diagnose the starting problem and proceed with repairs.

Cranks over start than dies
ANSWER : Hi There,
The idle air control valve is a small valve on the engine’s intake system that reads the air intake as it comes into the motor. This is controlled by the car’s ECM which uses this information to make adjustments to the air/fuel ratio depending on various inputs such as outside air temperature, intake air temperature, load and various other things. As you accelerate, your car’s engine is receiving a much higher dose of fuel than when at idle and conversely, when you let off the gas pedal, there is a sudden change in this fuel supply as a result of your foot letting off the pedal. When this happens, the job of the idle air control valve is to bring this deceleration down to a slow and smooth idle rather than suddenly cutting off the fuel supply causing the motor to die. When the idle air control valve is not working properly, this cause a disruption in this process resulting in the engine not being able to idle properly. I would recommend having a professional come to your location to diagnose and inspect your vehicle.

Why does my car struggle to start every 4th to 5th time?
ANSWER : It sounds like your starting issues may be linked to a problem with air metering or fuel delivery. A clogged or malfunctioning idle air control valve may show some of the same symptoms you are describing. The idle air control valve can be stuck in a cold start position which may work well if the car has been sitting a few hours, but as the engine warms up there must be a regulation in airflow. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look at your hard start situation and offer a more personal diagnosis.

When I start my car it doesn’t start after the jump start it started but later it didn’t and the battery was last replaced on 9/2012
ANSWER : As you may know when jump starting the car, the battery power provided is being supplied form the other car you are using to jump your car with. If the car does not start following the jump, this would suggest your battery may be dead and needs to be replaced. If the battery was last replaced in 9/2012, it is most likely time for a new battery as that is a decent amount of life for a battery.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
