My truck will not start.
My truck was starting fine and then began to make a crunching scraping noise in what sounded like the drivers side. However it would start. Then after a few times it stopped starting when I turn the key and I am met with a very low gear sound almost like a low hum. It has a brand new starter and solenoid because it was having trouble starting a few weeks ago but the problem was solved by wiring around the ignition and installing a start switch which I would push after inserting and turning the key to make the truck start.
My car has 372494 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
From the description of your symptoms, it sounds as if you may have damage on either the new starter or the ring gear on the engine side that is driven when the stater is activated. This can be checked by removing the starter and looking at the teeth on the starter and on the ring gear on the engine which you will be able to see once the starter is removed. Consider hiring an experienced technician like one from YourMechanic who can come out for a closer look to offer a more personal diagnosis of your no start situation.
How to Identify and Fix Common car Problems ?

The most common reasons a Ford F-150 won`t start are a dead battery, an alternator problem, or failed starter.
If you only hear a single click as you try to start the car, it could be an electrical problem with the starter solenoid or starter relay. A faulty or corroded starter solenoid tends to absorb the electrical current meant for the starter motor.
won`t start and there`s no clicking noise, the most likely cause is a problem with your vehicle`s starter system. It could be a problem with the starter itself—such as a loose connecting wire or blown fuse—or it could be that a component in the system has worn out or needs replacing, such as the solenoid.
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.
Some other typical reasons engines fail to start include:
Low or discharged battery. Corroded or loose battery cables. Starter motor relay failure. Ignition switch failure.
The ignition relay is one of the most important electronic relays found on modern vehicles. It is usually located in the fuse and relay panel beneath the hood, and is responsible for providing power to the vehicle`s ignition system, and some of the fuel system`s components.
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won`t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.
Why won`t my car start but the battery is good? If your car won`t start but the battery is good, the most common cause is a faulty starter – though it could also be to do with your fuel. You may have insufficient fuel to get the car going.
If you don`t hear clicking when you start the engine, the problem may be a dead battery. If you hear clicking, but the engine doesn`t crank, the starter might not be getting enough electricity. Using your owner`s manual and a voltmeter, you should be able to test functionality.
The most common reasons a Ford F-150 engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
If there is no sound when you turn the key, but the lights and accessories work, it could be the stater relay or starter solenoid. However if there is no sound at all, not even a click, it`s probably your battery.
Clicking when starting usually means the starter motor pinion gear is crashing into the flywheel due to a depleted battery that doesn`t have enough “juice” to spin the engine.
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.
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.
The crankshaft position sensor monitors the position and speed of the crankshaft and other parameters that play an important role when starting the engine. If the crankshaft position sensor is having a problem, the vehicle may have intermittent starting issues or not start at all.
Car suddenly stalls while operating: One of the most common symptoms of a failed ignition relay is a car that suddenly stalls while operating. If the ignition relay shorts, burns out, or otherwise fails while the engine is operating it will cut off power to the fuel pump and ignition system.
Usually, a blown fuse just causes a minor car electrical problem, like backup lights or interior lights not working, not being able to use your radio, losing a turn signal, or some of your climate control features not functioning properly. In rare cases, though, a blown fuse can mean that your car won`t start.
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 can be hard to determine if you`re dealing with a battery or an alternator problem.

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.

I changed the fuel pump and truck ran great for 3 days. Now after 3 days, the truck dies. It will start running for a few minutes, then dies like before.
ANSWER : Hi there, thanks for writing in. I’d be happy to help. It sounds like you should disconnect the connector to the fuel pump and inspect it for any signs of getting hot. The female connections may be too loose on the fuel pump and lose contact after running and getting hot. If there are indeed any signs of problems, then I’d suggest replacing connector and adding dielectric lube to pins before installation. This should solve the problem, but if you continue to experience issues, feel free to reach out to us for help again.

I parked my truck for 5-10 mins. Tried to turn it on, now it wont start, called a tow tow truck 15-20mins later my truck turned on
ANSWER : It is very likely that you have a powertrain control module failure. This can happen often on many GM vehicles. I would recommend having the powertrain control module tested and replaced as necessary in order to resolve this issue. After the powertrain control module is replaced, a reflash procedure will be required so that the vehicle can relearn all of its primary engine data. Once the reflash is completed, your vehicle should no longer have this issue.

Truck won’t start in morning. 2nd day now. Battery seems good.
ANSWER : Since the symptoms changed when you touched the battery terminal, it leads me to believe you may have a poor connection and the main battery terminals. If they are badly corroded or have any small cracks, the terminal may be too loose on the battery. You can rule out the battery by removing the connection to the vehicle then testing the battery itself. If the battery is good then reattach the terminals, tighten them and see if you are able to wiggle them on the posts. If the terminal still moves, replace the entire cable. You can cut the terminal ends and replace them, but you will never get as perfect a connection as replacing the whole cable. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at the loss of electrical power situation and run tests to offer a more personal diagnosis.

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.

My 2011 truck does not start all lights on dashboard turn on like normal but it will not start and it started showing a advancetra
ANSWER : Hi there. If you are able to turn the key and the engine cranks over; but won’t ignite, the issue will be caused by an ignition or fuel system component failure. If you are unable to crank the engine over, this is due to either the ignition relay or the starter itself. You might benefit from having one of our mobile mechanics come to your location and complete a car is hard to start inspection.

My truck died while driving. Now will start, but dies when I push brake. If I start in neutral, I can put in drive and go but dies – 2003 Ford F250
ANSWER : Hello – your symptoms suggest that once your cold start features are no longer needed – engine warming up – there is an air "leak" that ruins low speed running. Causes could be a leaking exhaust gas recirculation (EGR) valve, or leak in the air intake. A failing fuel pump relay (burned contacts) could cause similar behavior, contacts become hot, then won’t pass enough current to run the pump. Failing pump can also act this way – gets hot and fails. I recommend a starts, then dies 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.

Security light flashing. No crank no start. After truck sits with battery disconnected,the truck will start and run. Is it the BCM
ANSWER : Typically when the battery has been disconnected for an extended period and is replaced, an error code will be triggered in the ECU of the vehicle and disable the ignition system. This is done as a security feature; but tends to be a major inconvenience for car owners. The only way to resolve this issue is to have a professional mechanic complete a check engine light inspection, so they can download the stored error code, clear the code and verify that the car will start. If this is not the problem, a more in-depth inspection will need to happen.
