72 Chevelle cranks but won’t start and has to be flooded but smell no gas
My 72 Chevelle hasn't been started about 18 mths, carb was sticking open like full throttle last time I started it. It sits much more than driven almost 27 years. I got a rebuilt battery, cranking good,, a guy pours gas into my carb to start it and it cranks but won't start, maybe for a partial second a few times. I told this guy i did not want to dry start it after not being started for so long and that was all he did and concluded it was the fuel pump.
I let it set a few days then went to start and still cranks but don't start so I decided to pump it to flood it and I smelt no g

Experienced mechanics share their insights in answering this question :
Gasoline is generally not usable after 3 to 6 months. If gasoline has been stored in the vehicle for a lengthy time, the problem is likely that there is just simply nothing to combust. The volatile components in the gas have evaporated and other compounds in the gas have turned to varnish and gum, possibly plugging up the carburetor. If the tank was drained though and the fuel in the fuel system is fresh, please simply request a no start diagnostic and the responding certified mechanic will pinpoint the cause of the no start condition.

How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
If your carbureted engine turns or cranks but won`t start, there`s not enough fuel or spark. Here`s what could be causing your engine to crank: Bad crankshaft position sensor. Clogged fuel injectors.
Odds are, if you smell gas while cranking the engine, it`s getting fuel. It`s probably not getting spark. Common causes for no spark: Bad crankshaft sensor. Bad camshaft sensor.
First off, when you have to continually press the gas pedal in order for the engine to start, it means one of two things – either the engine is not getting the right amount of air/fuel ratio or it`s unable to ignite that mixture of fuel and air.
Using old fuel in your car can sap engine power, causing hesitation and stalling. The worst case is that your car might not start.
Vehicle Won`t Start or Struggles When Starting
If the fuel injector is not delivering enough fuel to the engine system, this can cause the car to struggle when trying to turn over or not turn over at all (just cranks with no result). This can also cause the engine to stall due to the air-fuel ratio not being correct.
The source of a “cranks, but no start” problem on your Chevy 350 distributor install is most likely incorrect distributor alignment with the harmonic balancer or a mismatched balancer and timing tab.
If you notice a burning smell from the car and now it won`t start, this could be a sign of engine damage. Have your car towed to the nearest mechanic, where a professional can inspect the burning smell coming from the engine. Your insurance may even cover the tow if you have roadside assistance on your policy.
Bad fuel pressure – if your vehicle has as issue with fuel pressure it could lead to a smell of gas.
Car stutters and stumbles—the first sign of a bad fuel pump is intermittent coughing and sputtering that can`t be explained. If you`re sharp, you`ll fix the problem at this stage before it gets worse. Excessive whine from the fuel pump—modern electric fuel pumps will get noisy before failing.
Fuel stabilizer keeps gasoline, especially gas with ethanol (E10, E15), from going bad in a vehicle being stored for a half-year or more. Dry gas is the generic term for an additive that works to keep water in the tank or fuel lines from freezing. (Drygas is the brand name of one such product.)
Longer cranking times are common among older vehicles due to the worn-down components.
To start an engine that has old gas in it, you may need to pump fresh fuel into the system from an external source. You may also need to completely remove the old gas from the tank and fuel lines before trying to start the engine.
If the fuel pump fails completely — to the point of not being able to provide enough fuel for the engine to run, the vehicle will refuse to start. The engine will still crank when the key is turned, but it will be unable to start due to the lack of fuel.
Problem Description. If the engine cranks but does not start, or starts and stalls, the fuses should be inspected, especially the power door locks fuse. The power door lock fuse provides power to a module that sends the Powertrain Control Module (PCM) the “OK to start” signal.
Fortunately (spoiler alert) the root cause of a no-crank is almost always simple. Most of the time it`s simply due to a low or dead battery, or voltage drop through a corroded connection. Rule those out before you suspect the starter itself.
Your car battery contains sulfuric acid. Usually, the sulfuric acid stays in the battery case and doesn`t cause any problems. But if your car battery suffers any damage, the sulfuric acid can leak out, causing that rotten egg odor.
The rotten eggs smell usually indicates that something sulfurous isn`t working properly. That can be harmful. So you shouldn`t drive a car that smells like rotten eggs.
On most modern cars, fuel injectors located in the intake or inserted directly into the engine itself spray a precise amount of fuel during each cycle. If the seals around these injectors degrade, or a leak develops in a fuel line leading to the engine, you may be able to smell gas.
Smell or see smoke when starting the motor
Sometimes the starter will overheat because of continued power being supplied to the starter or the starter motor will not shut off after the car`s engine has ignited. If this occurs, you`ll most likely see or smell smoke coming from underneath the engine.
Strong Odors
If your vehicle`s exhaust emits strong fumes, it could be a sign of a dirty fuel filter. It could mean other damaging issues are at play, as well. Whatever the case, foul odors mean you should have a professional take a look as soon as possible.
Surging Engine
The flipside to not enough fuel is too much fuel and a fuel pump that is going out can send too much fuel to your engine, too. You`ll notice your engine surging when this happens and the surges can make driving dangerous. Surges mean the vehicle picks up and then drops speed. Not good on the road.
The most common reason a pump fails is wear on the pump from improper lubrication or over-use. The best way to explain a failed fuel pump due to wear and tear is to explain what other reasons may have lead to a failed pump: Most fuel pumps are lubricated by the fuel in the tank itself.
This is important – if the starter motor sounds like it`s turning over, as usual, your issue is probably the battery. If the engine cranks but doesn`t start, it could be having trouble producing a spark, getting fuel, or creating compression.

The car crank but won’t start
ANSWER : Hi there. This does sound like an issue with the wiring. If the check engine light is coming on every now and then this means that when it does not come on there is no power to the computer. This can be the wiring harness issue or an ignition switch problem. I would have to test for voltage to the computer when the problem is occurring to be able to find where the issue lies. If you need assistance, a certified YourMechanic technician can be dispatched to your location to inspect your vehicle’s non-start issue and suggest any necessary repairs.

ANSWER : Hey there thanks for writing in about your 1998 Honda Accord. This could be a few things. A faulty ignition switch, a failing crank sensor, or possibly other faulty sensors could be the cause. To have this taken care of, consider having a certified technician, such as one from YourMechanic, come to your car’s location to diagnose and repair the hard start issue.
Why doesn’t car start after running out of gas girlfriend ran gas out of car now won’t start plenty of gas in tank doesn’t sound l
ANSWER : Fuel pumps rely on liquid gasoline for cooling. Consequently, it is recommended to keep the fuel tank at least 1/4 full to prevent the fuel pump from overheating. If the pump is run to the point of being dry, the seal on the impeller can overheat and get damaged. Even if the pump subsequently runs, as you report your does, it cannot develop enough suction to pick up fuel due to the seal damage. That is possibly what has happened in your case but it should be confirmed prior to replacing the fuel pump. In your circumstance the recommended service is fuel pump replacement but if you request that, the responding certified mechanic will do enough tests to confirm that there is no other possible explanation for the failure. There is a quick and direct way to determine if the problem is lack of fuel. Procure a can of "starter fluid" from any department store. Using the material cautiously (it is highly flammable; keep away from flames or sparks), introduce some of the fluid into the intake of the engine while you engage the starter motor. If the vehicle starts and runs briefly, then you know for sure the problem is fuel starvation of course almost undoubtedly caused by the pump failing. Fuel pump replacement can be accomplished in the field, right at your location, if you desire that service.
my 2003 saturn ion won’t start. it cranks but won’t start.
ANSWER : Hi there:
If you checked the oil and determined that there was no oil in the car, it’s quite possible that some internal engine components have seized up; which means there might be serious engine damage internally. Before you attempt to crank it again, please contact a professional mobile mechanic to complete a car is hard to start inspection; so they can pinpoint what is the source of your issues before it causes more damage.
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.

ANSWER : Hi there. It sounds like you have a failed starter. However, without proper testing there is no way to be 100% sure. I suggest having the battery tested first with a digital battery tester that provides current voltage, cold cranking amps, and state of health. Also inspect for corrosion on the terminals and cables as this will cause excessive resistance and not allow proper voltage/amps to the starter. Other possible failures could be in the wiring harness, relay, fuses, or communication network. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a car does not start inspection.
Car won’t start, can smell gas, started 10 min later.
ANSWER : Hi There,
This is likely related to your EVAP emissions system and something called a purge valve solenoid. 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. When this is not working properly, you may experience the gas pump shutting off prematurely causing it to take a very long time to fill up your fuel tank. This is due to the excess fuel vapor that is present when the purge solenoid is not working properly by releasing these vapors. The gas pumps at the fuel station have automatic sensors on them (for safety reasons) that shut off automatically when too much fuel vapor is present. I would recommend having an expert from Your Mechanic come to your home to take a look at your car to diagnose your EVAP purge solenoid.
