Every engine requires four basic ingredients to start: sufficient
cranking speed, good compression, adequate ignition voltage (with correct
timing) and fuel (a relatively rich air/fuel mixture initially). So any time an
engine fails to start, you can assume it lacks one of these four essential
ingredients. But which one?
To find you, you need to analyze the situation. If the engine won't
crank, you are probably dealing with a starter or battery problem.
If an engine cranks but refuses to start, it lacks ignition, fuel or
compression. Was it running fine but quit suddenly? The most likely causes here
would be a failed fuel pump, ignition module or broken overhead cam timing
belt.
ENGINE CRANKS BUT WILL NOT START
When the engine cranks normally but won't start,
you need to check ignition, fuel and"http://www.aa1car.com/library/compression.htm".
Ignition is easy enough to check with a spark tester or by positioning a plug
wire near a good ground. No spark? The most likely causes would be a failed
ignition module, distributor pickup.
ENGINE CRANKS AND HAS SPARK BUT WILL NOT START
If you see a good hot spark when you crank the engine, but it
won't start, check for fuel. The problem might be a.
On an older engine with a pump the throttle linkage and look for fuel squirting into the carburetor
throat. No fuel? Possible causes include a stuck needle valve in the carburetor, a plugged fuel line or fuel filter.
There is also the possibility that the fuel in the tank may be
heavily contaminated with water or overloaded with alcohol. If the tank was
just filled might
be causing the problem.
Even if there is fuel and it is being delivered to the engine, a
massive could
be preventing the engine from starting. A large enough vacuum leak will lean
out the air/fuel ratio to such an extent that the mixture won't ignite. An EGR
valve that is stuck wide open, a disconnected PCV hose, loose vacuum hose for
the power brake booster, or similar leak could be the culprit. Check all vacuum
connections and listen for unusual sucking noises while cranking.
as you said you have codes you can check out from codes which part out of this is faulty.and you can get that particular part replaced.
This will help. Thanks please keep updated.please do rate the solution
if helped.thank you for using fixya.
