Cultus EFI 2008, Engine goes off itself and doesn't starts

[khalilchauhdry]

Hi everyone,
I'm using Cultus EFI 2008, it have some problems with engine. It runs perfectly even i go on 1000km continuously but in city it creates problems when the engine heated up with AC at its limit level, its RPM goes down even using Petrol/CNG, when i stops it on road side or some chowk or elsewhere with AC running, after 5-6 minutes it goes down and gets off itself. Then it doesn't starts, even i change it to Petrol/CNG or vice versa but in vain, after sometime it goes start.
If i stops the car & turns it off myself then it starts normally & sometimes creates same problem.
,
Also, the car blows huge white smoke while starting and the smoke vanishes when i drive it about 5_6km.
The overall running of car have no problem, even it easily gets upto 130km/h speed.

Your engine cooling system has issues get the radiator and the head gasket checked... Also get you idle control sensors checked..

Leaky injector issue.....or fuel pressure regulator issue

Thanx dear,
But I'm from Vehari city near Multan...
There's no proper mechanic for Cultus.
5-6 electricians have checked it, recommended by diff mechanics but in vain.
The interesting results they give
"Car bech do ty hor ly lo"...

Well dear,
But if the cooling system has issues then why it goes without any problem on highways??
Even 1000km continuously driven??
Problem creats when it turns off itself.
When mannulay turns off and after 10-minutes np problem in starting.
Sensors are also checked by the electrician and he says all ok!

[omersiddiqui5482]

I suggested heating issues die to the white smoke which means that water is inside the combustion chamber.. also one of my colleagues had the same issue with his city while he drove on cng. The problem was in the ECU.

[khalilchauhdry]

Thanx for reply dear,
,
One more thing,
The cooling fan system is direct and when i switch off the fan then start the car it exhausts less smoke and when i start the fan it gives much extra smoke.
Also if i start the car and go on at once then smoke exhausted is less than if i start the car & let it for 5-6 minutes then start to drive.

[omersiddiqui5482]

First thing. Never keep fans on direct.

How come you manually switch on and off the fan. Sir get the car pressure tested and go to someone mechanoc who has a scan tool and who can scan ur cars system.

[khalilchauhdry]

First

That's good,
But what we do when our mechanics/electrician have done this???
& we he knows better than us??
,
Please suggest if you know any good one in Multan area?
Who can scan for errors as well have a good solution for it.
Otherwise mostly are saying that one valve of engine is not working properly so that the cars blows smoke and they suggest to change valves and gaskit.

[omersiddiqui5482]

And how do they know that this issue is due to a bad valve..

Bhai the thing is that cars have been designed after alot of investment and experiments and they are engineered to be what they are from the manufacturer.

Change battery and wire which connects with distributer

[khalilchauhdry]

Change

Brother battery is new still under warranty,
But not resolved the issue!
Wires not changed,
Still original.

[khalilchauhdry]

And

Brother,
How they know, "i don't know"
But one thing they say "Mistri asi wa ya tusi?"
Yesterday One friend said "change the plug,coil wires to Orange wires", if it possible??
,
Now a days its winter and car blows much smoke, which is noticed by everyone & creates tension for me.

[omersiddiqui5482]

is there any suzuki authorized dealership in your area.

Sir this the the problem mechanics dont listen to the owners. What difference does the oranges, red or blue HT leads make?

[khalilchauhdry]

is

Yes dear,
There's Suzuki dealer in Vehari, near to me,
But they are Totally Daaku....
"500 ka kam 5000 mn"
Diff
I don't know,
Just a friend suggested,
So "i was asking you being expert if this trick would work or not"?
,
Thanx for your continues replies!!

[omersiddiqui5482]

I am not an expert sir. I am still learning...

Color of the HT leads don't make a difference of a single penny.

Every dealership does this. But they will have a scan tool and a compression tester. Your basic concern is to get the car scanned and compression tested

Yes,

Thanx for your assistance!
