Luke came and replaced starter yesterday this morning car is not wanting to shut off its starting itself back up, evythng flashing

Starter replaced yesterday by a mechanic Luke. Check engine light still on. I tried to shut the car off and it was sounding funny like it was trying to start back up. So i turned the key a tad and it started up on its own. Then everything started flashing and the hyundai symbol in the middle of the dash kept coming up then switching back to ny gas mileage. I tried cutting it back off and it did the same, smells like rubber is burning so i just shut it off and took key conpletely out. Im not sure if something was left unhooked or something. The starter was just replaced yesterday afternoon

Hi there. What you are describing is very odd as being a symptom of a starter replacement. In most cases, if there is continued electrical problems or warning lights that illuminate, it’s due to a trouble code that was either not reset after a repair was completed, or the code is caused by something different that was not replaced or repaired.

Common reasons for this to happen:

Low fuel pressure, dirty or defective fuel injectors, or broken fuel pump: The fuel pump is responsible for transferring fuel from the tank to the engine.

The most common reasons a Hyundai Sonata 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.
If the vehicle randomly shuts off while driving or stationary, there is usually an issue with the engine. Typical patterns here are issues with the ignition system, mixture preparation or fuel. A known error here is that the vehicle was refueled with the wrong type of fuel.
The alternator helps to manage the supply of electricity by recharging the battery. When there is a bad alternator, your car will shut off while driving. This primarily happens as it affects the power supply. Alternator issues will make the engine lose power.
Possible causes of a power failure could be either bad battery connections, a bad ignition switch, or a bad alternator. What you need to do is check your vehicle`s power sources.
Connected to the battery is the alternator, which works to generate power for your vehicle`s electrical components. When you have a brand-new battery but still can`t start the car, the alternator might be the issue. Cold and damp climates may increase wear on an alternator, causing it to fail.
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.

ANSWER : Hi there. What you are describing is very odd as being a symptom of a starter replacement. In most cases, if there is continued electrical problems or warning lights that illuminate, it’s due to a trouble code that was either not reset after a repair was completed, or the code is caused by something different that was not replaced or repaired.

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.

My car shuts off while driving and then turns back on multiple times or shuts off after driving and car turns off.
ANSWER : Hi there. Check the alternator and make sure that the wiring it connected tight. Check the battery cables and make sure that they are tight and clean. Look for any loose ground wires to the chassis on the vehicle. If everything checks out to be working correctly, then the PCM may need to be replaced as it may have a battery disconnect condition. If you need further assistance with multiple functions shutting off, then seek out a professional, such as one from Your Mechanic, to help you.

Since the starter was replaced in 2014, is it possible that the starter needs replaced again as car is not able to start?
ANSWER : It would help knowing the model of Mercury car you have for more specific advice. It would be uncommon for a starter to only last less than two years. I would have the starting system diagnosed by a trustworthy technician to make sure you do not have a bad cable that is not getting enough power to the starter.

Car will not crank after putting in a new starter. Forced starter to start up and engine starts but stalls out. Will the security continue to cut off fuel while force starting?
ANSWER : Hi there. Forcing the starter to engage to make the engine run without the ignition engaging the starter will continue to keep the security on. This is a safety feature that keeps people from stealing your vehicle. I recommend replacing the ignition switch and checking the wires to make sure that they are all tight and clean. If you need further assistance with diagnosing your ignition problem, then seek out a professional, such as one from Your Mechanic, to help you.

My car want start and when it do it shut down and want start until 30 minute or so. Now it want do nothing
ANSWER : When a car turns and won’t start, it is called a "crank no start". When this occurs, the first thing you need to do is see what is missing. All internal combustion motors need spark, fuel, injector pulse and camshaft timing to run. If one of these is missing, you have a crank no start. Diagnose the car and see what is missing.

The GM 3.8l motor has been installed in Buicks, Pontiacs and Chevrolets for decades. Particularly during the 90’s and early 00’s, these motors have used an ignition module with three coils mounted to it. This module is prone to just this type of failure. When it gets too hot, it quits working. When it cools off, it starts again. It can also display intermittent no start conditions. This is a pattern failure on this particular motor. Before I would ever replace the module, I would check for spark and injector pulse. If it just lacks spark, I would check for a crank sensor signal and replace the ignition module.

Before we get too far ahead of ourselves, do a few tests first:

Check fuel pressure. If there is none, check the fuse and the relay.
Check for injector pulse with a noid light. If this is missing, I would suspect a crank sensor. It could be a bad Power Control Module (PCM). (PCM’s are very rare to fail. I have never changed a PCM on one of these cars.)
Check for spark with a spark tester. If it is lacking spark but has injector pulse, suspect the ignition module.

If all these are present, I would take a compression test of all the cylinders. If camshaft timing is off, several of the cylinders will have significantly lower compression. Also, camshaft timing won’t start sometimes then not others; it will either start and run bad or it won’t start at all. It may sound like it is trying to start, but it won’t start.

If all of this sounds to daunting, I recommend booking a car is not starting inspection with YourMechanic

Good luck!

2005 Chrysler 300C changed battery and alternator. Car started, ran, and then battery light came on. Shut car off and wouldn’t start.
ANSWER : Hi. There is a couple of things that could be wrong here. The battery or alternator that was just installed could be defective. Theses parts need to be tested for proper operation. There also could be a fuse, fusible link, or wiring for the battery or charging system that is blown or broken causing the battery light to come on.

The codes that you have will cause the car to shut down, run rough, or not start at all. The crankshaft sensor and camshaft sensor should be replaced. I suggest having a certified technician from YourMechanic come diagnose the charging system and check engine codes to help you proceed with correct repairs.

My car stutter starts, but only after driving it for a few minutes.
ANSWER : Hey there. This may also be caused by what is called the fuel pressure regulator. This is a unit that helps to maintain the fuel pressure at the proper level. When this is not working properly, the fuel pump may be pumping properly, but the fuel may not arrive at the fuel injectors at the proper psi. When this happens, this can cause a lean fuel condition which may cause the car to hesitate, misfire, or stall. If you would like to have an expert pinpoint the issue, a certified professional from YourMechanic can come to your car’s location to inspect the hard start problem and confirm which repairs are needed.
