Turns over but won’t start.. 2001 Chevrolet Blazer
So every day when I first start to crank my blazer, (2001 Chevy blazer 2wd, 2door, 4.3) the motor will turn and turn but not start. If I spray starting fluid through breather and try to start it will crank and run until I cut it off. If it sits for a couple hours it will do the same thing, wont start til I use starting fluid. Rarely sometimes it will crank the second time without fluid. I've changed crank sensor, new battery, cap and rotor, it has ngk iridium plugs, new wires, checked fuel pressure which is at 62, new fuel filter, pump does engage when key is turned. I have fuel, spark, co
Experienced mechanics share their insights in answering this question :
Hello – your symptoms and diagnostic efforts still make me suspect that there isn’t adequate fuel pressure when you first try to crank it. The fact that it sometimes starts on the second effort reinforces this. If the fuel check valve/fuel pressure regulator is allowing the fuel pressure to completely drop overnight, the fuel pump has to run longer to bring pressure up to where the injectors actually deliver fuel. Leaving the fuel pressure gauge attached overnight, so that you can watch fuel pressure on first startup will provide guidance as to whether this is the case. I recommend a hard start inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
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 Chevrolet Blazer won`t start are a dead battery, an alternator problem, or failed starter.
The most common reasons a Chevrolet S10 won`t start are a dead battery, an alternator problem, or failed starter.
An engine that is hesitating to accelerate is most likely dealing with a fuel/air mixture that is too lean. Engine`s that are running inefficiently will begin to show signs like hesitation which will only become worse over time.
Reasons a Chevrolet Blazer Heater Isn`t Working. The most common reasons a Chevrolet Blazer heater isn`t working are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.

If the car cranks when you turn the key, but the engine won`t start, it could be because fuel isn`t getting to the engine. One potential reason for this could be dirty fuel injectors. Over time, the fuel injector nozzles can become clogged with rust, corrosion or debris.
When your engine cranks but won`t start or run, it could mean your engine is having trouble producing a spark, getting fuel, or creating compression. The most common causes are problems in the ignition (for example, a bad ignition coil) or fuel system (for example, a clogged fuel filter).
Bad Alternator
If your car won`t start, but your battery is fine, chances are you have a bad alternator. This is another charging system issue, like a dead battery, that won`t let you start your car.
This hesitation while accelerating can be the result of a number of issues, including something like a clogged fuel filter or even a broken fuel pump. Sometimes, something could also be wrong with the transmission.
Trouble accelerating can come from a few different engine issues. These include, but are not limited to, dirty fuel injectors, low fuel pressure, and restricted airflow. A problem with the mass airflow sensor, throttle position sensor, or engine speed sensor can also cause a car to have difficulty picking up speed.
Across almost all models of cars and trucks, the number one cause for a vehicle`s heater to stop working is a faulty or broken thermostat.
Car Heater Not Blowing Hot Air: A Bad Blower Fan Motor
Either it`s not getting electrical power or, more likely, the motor itself has simply burned out. A blower motor in an older vehicle is likely to burn out over time, and may need replacement.
Here are some of the most common causes of why air doesn`t flow out of your vehicle`s vents: Your air intake is clogged, meaning that air isn`t getting in from the outside at all or isn`t circulating properly. There is a blown fuse in the ventilation system. Electrical issues such as a bad relay.
A Bad Crankshaft Position Sensor
The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.
With a cranking system, symptoms are divided into one of three possible troubleshooting categories: Click — No-Crank (solenoid clicks but starter doesn`t crank) No-Click — No-Crank (solenoid doesn`t click/starter doesn`t crank) Slow Crank (starter cranks, but engine RPM slow to start vehicle)
Leaking Injectors will cause:
Hard Starting. Poor Emissions. Oil thinning, which can lead to catastrophic engine failure. Hydro lock, which can lead to catastrophic engine failure.
If rusting is the issue, you can bypass the bad starter solenoid wire. To do so, use a 12V wire to directly provide current from the car`s battery to the point where the starter and solenoid connect. You`ll hear a click sound indicating that the connection is made. Now turn on your ignition system.
The battery can be fully charged but still not be able to start the vehicle if it is failing or has a dead cell. Other likely issues are the fuel pump, ignition switch, battery cables, starter, or a clogged fuel filter.
In that day, a cranking, no-start condition could easily be diagnosed by testing the available spark at the spark plug. If there was no spark, we touched a test light to the coil negative terminal to determine if the distributor contact points were switching the coil on/off (see Photo 1).

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.

Car won’t turn over. No lights come on when I turn it. Can’t even lock my doorsvor push the seat up or back.
ANSWER : Your probably correct, it sounds as though your battery is done. But it also sounds like you have charging system issues. I’m not sure that fixing your battery and charging system will solve the problem with the car shutting off, but it’s possible that it will and it’s a darned good place to start. By contacting Your Mechanic, you can have a technician come to your home or office to check out your car and help you figure out what to do next.

So I have a hyundai sonata se push to start. My car won’t turn on, power is working, I push tof start but it won’t crank. I don’t
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.

Every 3-4 months, my car won’t start. It does turn over though.
ANSWER : If your battery is weak or has bad connections to the battery, then you may have problems starting the vehicle intermittently. This is due to low voltage to the starter which is taking all the power, while the electronic ignition and the electric fuel pump get cut short. This will cause the vehicle not to start.
You may think the vehicle is turning over okay, but the starter is taking in all of the power just to turn over the motor. You should get the battery and it’s cables checked, as well as the charging system, for any problems by a qualified mechanic so they can diagnose the problem and do any repairs needed to prevent this problem in the future.

Car started with a jump start earlier today, but won’t start now despite turning over.
ANSWER : It’s possible that when you jump started the car the first time that an electrical relay may have been damaged. This is a very rare situation, but has been known to happen on some GM products like your Chevrolet Avalanche. It’s also possible that an ignition system component like the crankshaft position sensor or relay may also be faulty which wouldn’t be related to the battery. The best thing for you to do is have a mobile mechanic come to your home and complete a car is hard to start inspection, so they can pinpoint the source of your truck’s issues.

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.
