Technical Starting, problem or not ?

[Djordje111]

When I am starting my uno for the first time of that day, something strange hapens to me. Directly afther the motor is started the whole car begins to shake and quake, and short afther that it turs off.
Buth when I start the engine, and it it starts shaking I pres the gas pedal, hold it for the while and let it up, and there is no more shaking at "0 gas position"
Is this a problem or not ?
Another thing that wonders me is a oil preasure. Short afther I pres the gas pedal for some time a oil preasure indicator levels on almost 4/8 bars. Is this Ok, or not?
And one more stupid question, from a stupid man: What is a normal temperature ow wather in my engine ?

P.S. Sory on my bad english, and stupid questions.
I wana learn something

No, I don't think any one of those is a stupid question and the English is fine!

A stupid question would be, why didn't FIAT put a V8 in the Uno... Or a worse stupid question is something written in TXT-speak (not English) about "ur a losr"...! It happens on other forums.

I don't think the first problem is too bad and can be safely ignored as you have worked out a special technique. It's a diesel, isn't it? Maybe one of the glow plugs is not pre-heating correctly? It is possible to remove them (similar to spark plugs) to inspect - quite often, problems are easy to see (the end blackened or burned away). Other times the wiring is the problem - quite a common FIAT problem in general... As I said, something to look at when you have time maybe?

If this is a petrol engine, then there are frequently special steps to take with starting - even the handbook says to 'depress accelerator slightly'. I think that the handbook also says to use the hand throttle control to adjust the idle on the diesel engine. I think that later diesel models may not have this (next to the steering column).

The oil pressure should read at about half of the gauge (the 4 bar that you mention?) when the engine is at 2000+ RPM when cold, dropping as the engine warms up. I'd say that anything above 2 bar would be fine with the engine hot. At idle, the gauge may fall to about 2 bar when cold, and depending on the condition of the pressure gauge sender (!) sometimes almost 0-1 when hot. The oil pressure gauge sender is not very accurate, particularly when hot, so as long as the light doesn't ever come on, things are probably OK. In fact, 4 bar pressure is good news, nothing to worry about!

Water temperature should also be near the middle of the gauge - 90 degrees C is normal. 70 degrees C is OK, especially if outside air temperature is cold (near 0!). If the gauge reads 100 degrees, don't be too alarmed - the pressure in the system raises the boiling point to 120 degrees C so there's an extra safety-margin. Listen to make sure that the radiator fan runs at about this temperature.

If the temperature gauge reading is low (e.g. 60 degrees after a five kilometre drive) then the thermostat has probably stuck in the open position (quite a common failure). The worst thing is that the heater will be weak It's also not good for the engine to run cold, as condensation water will not be dried-out of the oil, and the fuel will not be vapourised so well and the engine will be less efficient. It's worth the price of a new thermostat in my opinion. Others may disagree...

Cheers,

First Alex I want to thank you on your great post. Some people say that there is no stupid questions, just a stupid answer. I realy do not beleave in this. Ofcourse there are stupid questions, buth I must ask them. I am so to say musician, and few mounts ago I didnot knew anything abouth cars. Buth I have a large progres, now I knew that a car has 4 wheels
And my english- its bad, and sometimes I feel you would not understand me, and sometimes I dont understand all of you people, all those strange words and parts Buth I will manage it somehow.

You brought a smile on my face. Because as you said in your post that with my engine(Yes its a diesel engine, as they said to me on this forum its a rare engine) is everything ok. I hope so

My glow plugs are conected with metal pipes, and I could take them of, buth I think that afther that I will never sucess in putting them back on old place, so I will let il someday to a mehanic.

So I should not be woried for the oil preasure. It changes in time. Buth the light on a bar never comes out, i am a hapy man

You said: "The oil pressure should read at about half of the gauge (the 4 bar that you mention?) when the engine is at 2000+ RPM when cold"
haha I cannot measure that, because I do not have RPM mether. Is this litle thing posible to put on my car ??? its wery useful for changing transmision. Or I should listen to the engine, like an old and expereanced driver

Wather temperature- So it should not be to hot,and also engine should not be to cold. Is it ok to start the engine, and than to wait few minutes for motor to warm up, and thar to drive it ???

Hi Georg,

The glow plugs are probably not the items you mentioned that have the metal pipes - those sound like the fuel injectors. Glow plugs have electrical wires.

2000RPM is about the revs you would be doing driving in town, in fourth gear - 60km/h = 2000RPM, at a guess! Most tachometers attach to the ignition system (coil and spark plugs) which a diesel engine does not have. So, it might be difficult to fit a tachometer - it would have to be designed for the diesel which usually means an extra sensor and wiring. You are probably best to rely on your experienced ear that you mentioned - when you are a seasoned driver!

Water temperature - it is best to start up and drive the car, rather than to leave it running to warm up. This is because it would take quite a long time to warm up when it is sitting 'idling', whereas it will warm up faster as you drive. But drive moderately - not maximum power When you have driven for about 5km, the temperature gauge needle should be at least one-third of the way across the gauge. If not, then either it is very cold outside (say, less than 5 degrees C) or the thermostat has stuck-open and should be replaced.

Sorry I probably use difficult words but I try not to - let me know if anything else doesn't make sense?

Hi Alex

Glow plugs, fuel injectors- I have shuffled it

anad the 2000RPM problem. You mentioned fourth gear. My uno has 5 of them so I supose should drive up to 60 km/h with a 5 speed and that is 2000RPM... ? Anyhow, it is suppose thereabout normal engine speed, not to hard not to slow, some middle ?
So the tachometer is hard to build in, ok I will forget ih and recline on my ears


And finaly wather hm so it is bether to turn on the car and drive it, (not maximum pover ) few kilomethers.
I have tried it today my neddle moves, so the thermostat is OK ? I hope it is

And again sory on stupid questions.

EDIT: And sory on much smileys, I am a quite hapy person

djordje kazi mi na srpskom sta te tacno muci, mislim da sam i ja imao takvih problema sa mojim unom i kazi mi koji model una imas????

[Djordje111]

aahahah na kraj svijeta pa na naseg cojeka naletih.
Vidi, muci mene hiljadu problema sa ovim unom. Neke sam vec rijesio a neke nezna odakle da pocnem. Model una je 1.3 dizelas 87ma 45 konja.
A problemi, kao sto rekoh mnogo ih je, nego nemogu da samram toliko ljude ovdje na forumu, vidim ionako slabo su voljni za pomoci pocetnicima.
Danas sam mijenjo remen klinasti jer je skripio i cvilio mnogo i stalno je gorjela lampica da se akumulator ne puni. Novi remen je stavljen i ne skripi vise nimalo, ali lampica i dalje gori, drug mi kaze da su cetkice na dinami pokvarene.
A paljenje, problem sa paljenjem mi je najgori. Ujutu had je motor hladan. Udjem ja u kola okrenem kontakt, sacekam da se izgasi lampica ze grijace, zaverglam auto upali, zatrese se i izgasi. Pa onda opet tako nekoliko puta. Posle 5,6 pokusaja situacija napreduje: zaverglam on se upali radi par sekundi pa se tek onda zatrese pa izgasi. E tad ja zaverglam i kad se upali dodam gas, al on se opet izgasi, i tako par puta, i onda odjednom primi gas i ja drzim gas pola minute, i pustim, i vise se ne gasi. Ovo bude jedino ujutru kad se prvi put pali auto. Posle kad se motor agrije, pali bez ikakvih problema, iz prve ma ko metak.

Inace imam i problema sa curenjem ulja, moram mijenjati dihtung na karteru, ali mislim da u ovoj nedodjiji nema da se kupi za moje auto, no nisam jos provjerio.
Eto to su moji problemi.

Pozdrav
Djordje

Znas kako ja na prvi pogled ne bih mogao tacno da ti kazem sta se desava.
Znam coveka koji radi samo fiatove modele, (IPAK JE OVO SRBIJA ) pa cu
da ga pitam o cemu se radi - to je prvi model una jel` tako?
A za lampicu od akumulatora, moj drug je iamo slican problem sa njegovim
uno jeste da je njegov uno 1.7 dizel ali fiat je fiat i ne verujem da je nesto preterano velika razlika! Poveri da li je alternator nivelisan lepo sa kaisem jer se desava da se alternator pomeri i da kais ne nalegne lepo!!!

Zaboravih da te pitam gde zivis???

Zivim u Republici srpskoj - Visegrad.
Sto se alternatora tice, kazem ti prije par dana sam mijenjao klinasti remen. Mislim ja sam pomago a drug je mijenjao, on je automehanicar naravno.
Remen je kupljen iste velicine kao i prethodni, i jedva smo ga nabacili. Alternator se otpusti ali za badava, nemoze pomocu klizaljke da se jos pomjeri, to jeste vec je vio da tako kazem na nuli, i remen kada je stavljen, sam od sebe je bio zategnut,tako da ga pomocu onih klizaca sa kojima na kojima stoji alternator, nije se mogao vise zategnuti. Znaci ostao je na nuli.

Danas sam takodje otkrio da se zadnja lijeva felga grije ko luda, ovaj jaran mi kaze da to rucna sajla ne otpusta, i da ce srediti to za 5 minuta.
A problem sa paljenjem je jos uvijek aktuelan.
EDIT: Da radi se o unu kecu

In English please???????????

 

[Djordje111]

In English please???????????

Sory for this, we are still talking abouth the same problems that I have(cold engine starst hard...etc). Its easyer to talk on serbian because its our mother tongue.

Is we alowed to talk on other languages here, or we must stay on english.

 

[antsuno2]

theres no problem, its all about sharing each others problems and experiences with our uno's, i wouldnt be able to help you with your problem not understanding serbian, you could pm him Ant!

 

[Djordje111]

Ok. Kuzman86 asked me to explain my problem on serbian, because I can explain my problem closer. He did not gave me any solution, he only asked what type of engyne I have and what problems. I said That I have problems, with cold start,

 

[Djordje111]

I will continue later, musto go

I said That I have problems, with cold start, problems with creaking belt(buth I have fixed it, put a new one), also I have problem with my aku charger, when I start my engine, aku lamp stil burns. I also have problems vith oil, it goes out of engine,
I must change some of these

And something like these i had

buth I have changed it,and the creak iz gone.

My uno realy needs lot of reparations
