Car stalling and dying

ANSWER : You should have the check engine light and engine scanned to see if the engine may be running lean due to low fuel pressures or clogged injectors. You should also have the mass airflow sensor cleaned and checked for proper readings and replace if not within specifications. The vehicle runs richer in colder weather and may be the reason for not stalling. You should clean injectors, clean throttle body and idle control valve then clean mass air sensor and relearn idle.

ANSWER : The initial failure was likely caused by a sudden fuel system (e.g., failed fuel pump) or electrical (including ignition) faiure. Prior to performing diagnostics be sure you have a fully charged battery that passes a load test. Then, confirm that the engine immobilizer system (security system) is not activated thus preventing the car from starting. If the starter motor is not functioning, check for power to the starter motor when the key is held in the "start" position. If there a large voltage drop at the starter motor or no power at all, you may have a faulty ignition switch but you do have to check out the entire starter circuit, which includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch and terminations. On the other hand, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. If you desire that a certified mechanic resolve this, please simply request a no start diagnostic and the responding certified mechanic will get the problem diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.

ANSWER : It is very possible that the engine has been damaged beyond repair. Usually when the oil light goes on and the vehicle is low on oil, especially when a loud noise is heard right before the vehicle died, it is very likely that the engine is blown and would require replacement in order to continue driving the vehicle. I would recommend having the vehicle checked with a no start inspection. Consider YourMechanic as this service can be completed at your home or office.

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

ANSWER : Hello there. This is a common fault as vehicles age and gain higher mileage. The most common faults for this type of symptom are the MAF sensor, spark plugs, coil, fuel pump, vacuum leak, or a wiring fault. In order to pinpoint the faulty component, it would be best to have a technician look at the car in person to let you know what’s going on. A mobile technician, such as one from YourMechanic, will be able to diagnose the stalling issue and perform the repairs required.

ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

ANSWER : Hi there. Usually when you shift into reverse and engage the brake it will cause the engine RPM to drop; as it’s creating a load against the transmission and the engine. If the engine stalls, it may be caused by a faulty idle control valve, bad O2 sensors, or clogged fuel injectors.

In regards to the "pan", we’re not sure what you are referring, so it may be a good idea to contact one of our local professional mechanics to complete a battery inspection to determine what’s going on with your 2010 Ford Focus.

ANSWER : A failing torque converter clutch solenoid is a common item to cause this sort of concern, but there are other parameters that must be looked into as well. A large vacuum leak can cause the engine to stall once the speed comes back down to idle, this is usually accompanied by a car that is difficult to start.
