Q: Car wont start, lights come on have new battery and altenator. When we jump start it itll work for a bit then die out.

asked by on

Car wont start, turn key and lights turn on, turn it to on and it dies. Battery is new and has a new alenator. When we get jump started itll run a little then just die.

If the engine is stalling immediately (almost runs but dies) typical causes for such immediate stalling are a faulty mass airflow sensor, faulty engine coolant temperature switch/sensor (typically at cold start only), faulty camshaft or crankshaft position sensors, worn spark plugs, wires or defective ignition coil(s), inadequate fuel delivery or pressure (clogged fuel filter, injectors, faulty fuel pump or pump circuit), contaminated or old gasoline, defective throttle position sensor, faulty idle air control valve, leaks in the EGR system, intake vacuum leaks, and so forth. If you request an engine stalling diagnostic the responding certified mechanic will get this resolved for you promptly. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
