Question : MY PROTON Iswara Aeroback 1.3 liter
has an intermittent starting problem.
At times, it requires about a dozen
cranks before the engine starts running while
occasionally it starts up on first turn. The car
had already been checked over by various
workshops but the problem persists. Please
help as no one seems to be able to pinpoint
where the problem lies.
Answer : Starting problems are difficult to track down
since most of them tend to be inconsistent in
nature. Some problems, are temperature related,
and you would often hear of vehicles that would
start easily when warm, but not when cold.
Others would start fine for a couple of weeks,
and then start with great difficulty on the odd
The first thing is to determine if the starting
problems are temperature related i.e. are you
experiencing problems starting the engine
before or after it has been running. Problems
starting when the engine is cold normally
relates to the cold starting mechanism and its
associated components, and in majority of cases,
a temperature sensor has failed, fooling' the
engine into thinking that it has already warmed
There are numerous reasons behind hot-start
problems. One is sensors giving false or incorrect
readings. Ignition leads that are in poor condition do not conduct as well when hot, and other
components such the ignition coil may cease
function altogether when warm, if it is faulty in
the first place. An authorized workshop would
be equipped with the tools to make a full diagnosis as to where the problem lies, thus saving
much time and costs in the long run.
