In an older car, with a carburetor, the engine may be 'flooding'. This can be caused by the choke being stuck closed (clean with some Gumout); carburetor floats stuck (service call for most people); pumping the gas pedal excessively during starting; or fouled spark plugs / bad spark plug wires / bad distributor cap.
In any car built in the last 15 years or so, suspect bad spark plugs or perhaps a defective fuel injection system. A leaking fuel injector will also cause that problem. A defective engine computer could cause that problem or many other problems.
Whats wrong when an 86 ford aerostar keeps trying to start after the engine is running?
It means that there is something wrong with the engine and not the battery
wired up wrong
You need gas in the car or a new engine that has to be fixed in the car.When someting is wrong with the engine, there's something wrong with the car.
Let it set for about 2 hours or push the accelerator pedal to the floor and hold it there while turning the engine over. Rarely do fuel injected engines flood. If they do then something is wrong with the firing system.
If your engine backfires when trying to start and the valve timing is correct, then it could be electronic ignition unit or the pick up that causes the spark to occur with wrong timing.
On an interference engine you can have internal engine damage when you attempt to start it. On a noninterference engine it may not start or it may backfire, or miss, if it does start.
Start with the basics. Is the battery fully charged? Are the battery post clean and tight. If you answer yes to both of these and the engine will not turn over and you hear nothing, suspect the starter, starter solenoid, or ignition switch is defective.
probably a blown head gasket.
Somthings wrong with the engine.
If you mean that the starter keeps spinning after the vehicle starts), the solenoid/relay switch is not releasing. In the START position, the relay spins the starter to start the engine and should release when the key is moved from START to RUN. Probably needs to be cleaned or replaced.
Engine will misfire, or may not start if enough wires are in the wrong place.
