Pls scan the car first, that direct connection to ignition might have caused it to have difficulty operating at closed loop, the engine's computer might be trying to make it enter close loop, thereby increasing the fuel trims.

Pls get the car scanned first before throwing parts

Good evening boss, I was working on a car today Corolla 2009 with a 2zr engine. Before accident, the car was starting fine without problems. During the course of repairs engine had to be removed. After the repairs engine was replaced everything was put back in place except for the airbags they were yet to be replaced because of funds. Here is the problem, I have spark, fuel, compression, at times it will do as if it wanna start but it won't start after a very long crank. No fault codes present In the Powertrain ECU. I'm just stuck as I don't know what to do, though the engine sat outside the car for about a week.

I really appreciate everybody's contribution, the fix was just a new set of spark plugs on all 4 cylinders

KINGreignn:
I don't know of any manual way. I use high end tools to run it.

I hope to save enough to buy one, what brand will you advice sir.

KINGreignn:
re-sync it back or else your car won't start.

Is there a manual way of doing it without scantool. As the scan tool I have is more like a generic one, it can only scan and clear codes for powertrain and see live data from the computer

AutoMoTech:
To check without removing valve cover you need a scope sir.
Best way to confirm timing is via a scope.

Sir Keh, I be small boy ooo, wanti6to learn from boss like you

AutoMoTech:
Confirm timing is correct...
Presence of air, fuel and spark at wrong time, d engine will never run.
Let us start with confirming ignition timing is correct.
If timing is correct , then lets check the sensors responsible for letting the computer know when to fire the ignition and injectors... These are the Cam and Crank sensors... Confirm they work as they should

Is there a way of checking it without a scope and without removing the valve cover

KINGreignn:
Was the ECU removed from the car at anytime?

Yes it was removed and returned back to the engine until it was fully re-installed because of theft.

Just take it to an electrician, it's normal, it's just a blown fuse

I think the check engine light on a 2004 sartun vue model is green. It means to use palm oil for the engine oil.

Go for a scan first.
It might need just to be recalibrated.
As the Corolla if that year model uses an EPS.

AutoMoTech:
Lwkmd. Like seriously? Bros and U dey talk dis thing confidently o...

Forgive my memory, I just got it clearly now. I'm being confused with duty cycle of electric motors as their speed is controlled by the percentage duty cycle and forgetting that injectors duty cycle varies the amount of time it will open, thinking it only controls rotary related components. I agree injectors are pulse width modulated.

09094566504

Inception:
It is PWM (pulse width modulated)

Injectors are not pulse width modulated, they are more like mechanical switches like that of relays.

First, I would like to see and know the value of the resistors added to it and how the modifications were made. Resistors will surely limit the amount of current pulsing the injectors. Thereby causing incomplete opening of the solenoids in the injectors. It might actually affect the spray pattern, whichever way it will still spray fuel. But what bothers me is will the new spray pattern allow for complete combustion that won't affect the engine's performance at higher RPM.

Get the car scanned first. I guess it has issues engaging gears. Has it been worked on before.

Phedam:
Hello guys,
I use a 2007 model VW jetta.
I just noticed some days back that while accelerating, my car suddenly jerks violently.
Let me explain better, If the car is at, say 40km/hr and I start accelerating,
when it gets to like 60 it stops increasing speed and starts jerking violently,
if I take my leg a bit away from the pedal and move at constant speed (60km/hr) for about 30 seconds
and then accelerate again it will respond to the acceleration until I get to like 80km/hr and it jerks again.
and the same cycle occurs at 100km/hr.

Please is there anybody with an idea of what can be going wrong with the car.
Responses will be appreciated.
Thanks

Get the car scanned, I can sense gear issue, it has difficulties engaging gears.

Perfecttouchade:
greetings chief, I have a BMW 316i....it won't start while attempting to start until the mechanic go to the bonnet and pass a little fuel through one small hose then it will start after 2 attempts, serviced the nozzles, change fuel pumps,coil as well but no difference, I got a rewire to work on it and after working for some days, it went back to the hard starting ish...kindly help with solution

The issue might be along the fuel line, check fuel pressure, check the fuel regulator.
When does it do hard start, is it when you want to start it after long hours of sitting or when few minutes after you stop the engine to restart??

BlackSeptember:
Remove oil from Saudi Arabia and you will find out that they are more primitive than Afghanistan.


There is no Muslim nation that became successful without natural resources. Their citizens don't think rather they slam their head on the ground 2hrs knocking out that which will spur their thinking

Go and remove it, mtcheew

NokiaN8:
please can I get a half tokunbo engine of E36 in Ilorin? please post the oics and ur number

Boss the best is to come to lagos

chiboy1116:
and u think this said Turkish company make all their stuff ? Even BMW doesn't make all the stuff used in their cars.

I no disagree, at least they are designed by there engineers

This list is incomplete, no BMW at all

ugkk:
No car manufacturer in the world produces all components needed in a vehicle itself

At least they design there engine, electrical system, car structure and write there programmes themselves.

imiski:
And Nigeria has innoson but we cannot help it grow. I tire for this country

As if innoson produces the vehicles themselves, they only assemble components collected from other manufacturers

samintegrity:
Same exact issue with my 05 accord.

Transmission won't shift pass 2nd gear, though still managing till am able to get a new one.


Now lately, it goes off just too frequently, sometimes when I put in reverse.

As a matter of fact, whenever I start in the morning to head out, it goes off like 4 times before it normalizes ..


Funny thing though happened yesterday,

I was driving, and the speedometer got to 40, it went off while I was on the main road oo showing the battery sign,

I put it off, tried to restart then no way, it didn't indicate the battery sign in dashboard, and also no light indicated on P as well.


I managed to pull over, left it and went for service.

Came back to it later in the evening, was able to get it to start again.

But then it went off like 3 times again.

So I start, put gear in 2 and fire all the way down to.my compound.


Observation: The driving belt was replaced abt 2 weeks ago but now losed, and its even half way on the power steering roll.

Observation 2 : the Rewire said the alternator doesn't charge as it shd, maybe due to bell

Any idea what the problem could be.

Check the tension in the belt. Diagnose the charging system.

timifakay:
Here's my #1 scanner. Nah dash them dash me sef, if I pull out others for a car, the car owner's 'this thing' will not be the same again. The best scan tool is a sound mind, which you can not buy.

Well done sir can I contact you privately sir.

autologic:
Honda doesnt provide such pids ,beside the type of fuel pump design is not duty cycle type but pure direct 12v actuated by PCM via relay
Diagnosis this type of issue will require scoping the current waveform of the fuel pump amperage draw for volume test and performing pressure test with appropriate pressure transducer, analysis of this test and amperage waveform will tell such precise story ,however this is beyond DIY but advance diagnosis .

The pressure transducer, Is it sold here in Nigeria, one that can be interfaced with any kinda scope??

Sir, with all due respect, get some one to help you write up your advertisement sir. It is not comprehensible sir.

Actually sir ,I think scanners like this are only limited to the Engine control module.

Awolowo86:
I used this one.
Or am I doing something wrong?

I don't know any, but you can go for a scan, and provide details of the car and the kind of issues your car have.
