Check the timing belt.
Whats wrong when an 86 ford aerostar keeps trying to start after the engine is running?
The engine will not start. Need a scaner to scan engine, to see whats wrong.
First you need to give a little more info.Will engine crank or not, is engine getting fuel.
engine has bad intake valve,
vapor lock
Timing needs adjustment is the most likely cause.
Your question is sort of backwards, perhaps you meant what causes engine failure? Engine failure causes...the engine to fail. If someone told me their engine failed I would take it to mean that it stopped running, or wouldn't start.
Why my infiniti QX56 doesn't want to start, the service engine light is on? is it because i stayed without gas, or whats causing for it not to start. A tuneup has been done..
A. No fuel B. No spark
Check the battery and the connections to the engine.
It's lean. You have to figure out why.
You probably have a little oil seeping into the combustion chamber while the engine is off. Once you start the engine, this oil is burned and causes the smoke you see.
