the car will rotate but it won’t crank and when it does rotate it sounds faster than it needs to be
i went out one morning to start the car and when i did it turned over but would not crank and but it will rotate and when it does it sounds faster than it should be.
My car has 25000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
It sounds like you broke a timing belt for the engine. You will need to have the engine compression tested. If you have low or no compression, then you may have broke the timing belt. The engine is an interference engine and may damage the valves if belt broke when engine was running. Have a trained mechanic inspect the no start in person to verify what the problem is.

If the timing belt does not move as you crank the engine, the belt is likely broken or is slipping on the gears. An inoperable timing belt will prevent the engine from starting. If the belt is moving, just be sure it has not slipped and that the engine is properly timed.
The most common reasons a Dodge Intrepid won`t start are a dead battery, an alternator problem, or failed starter. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
When your car`s timing belt is broken or irreplaceable, your engine will not be able to ignite or turn over properly. This means when you turn the key, you may hear the starter motor engage, but since the timing belt is responsible for operating the crank and shaft, it will not fully ignite.
A squealing noise could be from a lack of tension between the belt and pulleys. Worn belt ribs and a misaligned belt can result from an improper installation that can cause an annoying chirping sound. Timing belts are known to occasionally have a ticking sound as well that can stem from low engine oil or other issues.
When any changes are made to the engine of a car, the ignition timing is adjusted accordingly. If not, you could experience several problems with your engine with improper ignition timing like knocking, hard to start, increase fuel usage, overheating, and reduced power.
Engine Misfiring
The timing belt is responsible for synchronizing the valves and cylinders in your engine. If it slips too far or falls off the pulley system, it may cause one of the cylinders to open or close too early. This will cause a misfire, and a noticeable loss of acceleration.
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.
If your vehicle won`t start, it`s usually caused by a dying or dead battery, loose or corroded connection cables, a bad alternator or an issue with the starter.
It sounds like your engine is seized. If the timing belt or chain has broke then you may have bent the valves and the chain or belt will jam up the crankshaft from turning. The pistons will contact the calves and engine will not turn. Try and turn the engine in both directions.
If the timing belt snaps, there is nothing to stop the pistons and cylinders from colliding. This throws the rods off, and they start to poke holes in the engine block. Eventually, the engine will essentially break in half, and there`s no way to repair it. This is complete engine failure, and will require a new engine.
It is likely that one of your ribbed or slotted pulleys has seized up causing your belt to be unable to spin. It is also possible that there may be a problem with the crankshaft drive pulley.

Car won’t crank when it’s cold and now won’t start at all
ANSWER : Hi there:
Usually this issue is cased by low cranking amps inside the battery. If you’ve recently had the battery replaced, it’s possible that an electrical component that makes up the charging system might be damaged or faulty. It’s also quite possible that the main electrical relay or the starter relay is giving you fits. To know for certain what the exact issue might be on your 1989 Toyota Camry, you should have a professional mobile mechanic complete a car is hard to start inspection, so they can pinpoint the source of your issues and recommend the right repairs.
Car sounds like golf cart when revving and braking; also leaking fluid; sound fades as car warms up
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.
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.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
My car won’t start. Went to lunch came back out and When I crank it nothing happens.
ANSWER : It sounds like what you are describing may be related to a faulty starter relay. The starter relay directs power from the battery to the starter solenoid which then engages the starter when you turn the key. When this is not working properly, you may notice intermittent starting problems including no response when turning the key to start. Generally, when this does fail, it does so very randomly and usually without warning other than intermittent starting. The power from the battery will still power other accessories such as radio, horn, etc., but you may not have any power to the starter.
A faulty starter solenoid will generally produce a clicking sound when turning the key. The starter solenoid is located on the starter and has internal electrical contacts that transmit electricity to the starter. As electricity is supplied to the starter a small gear comes out and engages the flywheel to spin the engine over as you turn the key. When this fails, it may cause a clicking sound and will not allow the starter to engage the flywheel when you turn the key. I would recommend having an expert from YourMechanic come to your location to diagnose and inspect your vehicle.
my car heater gets warm but not hot.the car temp.is fine but i need more heat for the winter.does it sound like i need a new therm
ANSWER : It is possible that the thermostat is stuck open. When this happens, the engine can run much cooler than it is intended to. Running "too cool" can effect fuel mileage, emissions, and heater output. Most modern engines operate around or above the boiling point of water – 200-225 degrees. The thermostat generally opens when the coolant reaches 190-195 degrees. Part of it’s job is to restrict coolant flow so the engine can reach those temperatures. If the thermostat is open constantly, the engine may never reach operating temperatures. Have a certified technician inspect and/or replace the thermostat.
