my poor car |
|
|
Please I need information on my Nissan altima 1995 GXE manual
transmission. I bought this can January 2004 and by April of that year
it developed engine problem such that I had to change the engine
completely and after then it has been okay till about 3 months ago.
The problem is that when you start the car and you drive it around for
about 4hrs and you stop it, getting it to start again always prove
abortive except you leave it for let say 8 to 10 hrs then it will
suddenly start again.
From our diagnosis so far I have changed the distributor and ignition
coil. My auto mechanic has tried another fuel pump but the problem
keeps repeating itself.
Any hope?

with any problem, it's always best to start with an assessment of what
the problem is and *when* it occurs.
1. It only happens when the car has been driven and fully warmed up.
2. The car will only start after it's sat long enough to cool off.
3. Something is getting hot enough to cause a short or other condition
that prevents the car from properly starting until it (the part) cools
off.
Hence, it MUST be something related to starting a hot car.
There's only a couple of things that it can be and I'm surprised that
your technician hasn't started diagnosing that.
1. Throttlebody, either dirty or butterfly valve stuck closed. (e.g.
sensor is bad).
2. Too rich fuel mixture when hot starting. (see above).
3. Mass Air Flow sensor dirty or faulty.
Did your technician check the fuel pump assist or just the fuel pump?
Many cars have a second in-line pump that assists the fuel pump to
maintain pressure from the tank. These are usually located further up
the fuel line from the pump. If it goes bad, you can (actually will),
lose pressure, and the engine will run erractically..especially under
heavy accelleration. It can also cause starting problems because
there isn't enough pressure maintained. |

Hi Steve,
thanks for the reply. My auto technician only change the fuel pump and
the distributor, however I will get him to check the throttlebody, the
mass air flow sensor and the fuel pump assist hopefully that should do
it.
regards.

It is sad *you* have to teach your mechanic what he should do...
Shouldn't it be the other way around ? ;-)
Maybe you should try some other mechanic for a change ? |
