1.6 16v palio weekender injector light keeps flashing

[varesecrazy]

So it can't be cam timing then ?

very unlikely as it would not run well at times..

 

[Pieter groenewald]

Sometimes it runs right somtimes it doesn't I have raplaced the complete throttle body , ingnition coil, lamda sensor, air sensor and its still the same and a nother thing is that the fan starts running asoon as I switch the ignition on don't know what that can be

I don't know about that engine/ECU but on many MPI cars the radiator fan will come on immediately if the engine temperature sensor is faulty. A faulty engine temperature sensor is also a likely cause of over-fuelling.

The Palio engine is the common Fiat 1,6-16V used in many other models, like Marea, Stilo, Brava/O etc. etc.
Change the watertemp. sensor like I said before, and see what happens.

 

[Pieter groenewald]

I did change it now and the fan stil starts when I put ignition on and still injector light stays on

 

[Pieter groenewald]

I see on my thermostat housing there are 2 sensors I changed the one the thakes the plug with 3 points and next to him there a other sensor aswell by doesn't have a wire attaced and I can't find I wire aswell so I don't know

 

[Pieter groenewald]

And will it make a defrence if there's a thermostat in or not ?

 

[Peter Pick-Up]

A good working thermostat is necessary.

 

[Pieter groenewald]

But can it be if the thermostat is removed that it has something to do with the fan running from the start and the over feuling ?

 

[Peter Pick-Up]

No.
Somebody meshed up with the wiring.
Find a good workshop and have it fixed first.

 

[Pieter groenewald]

Ok I'm taking it to a guy monday he siad to me its the cam timing that's not right that's why the sensors is mulfunctionig can it be ?

 

[Peter Pick-Up]

Wait and see.
No cure, no pay.....!!!

Disconnect the battery and make sure it is FULLY charged. When you reconnect it, it may reset the ECU to default settings and 're-learn'. Some vehicles do, not sure about Fiats. Some vehicles have a ECU reset method, maybe the Fiat specialists can advise. I had the over-fueling problem, (plenty black smoke, no power), caused by the ECU keeping the injectors open all the time. The ECU also operates the fan. Have the ECU bench tested if possible or try a 'loaner', like call a friend. If the ECU needs fixing or replacing it will cost plenty.....several thousand Rand.

I took it to the guy today that kar pulls A LOT better he said the cam timing where out and he sit it right but the injector light is still on and still over feuling what can I do now ? Fiat charging me R6900 for new computer box but how do I now if its the ecu?

 

[fingers99]

Code read. The car is OBD2 compliant, any twerp with a code reader should be able to do it. Post the codes here.

 

[Peter Pick-Up]

The Palio Mk1 ( until 2002) is OBD1.......

 

[Pieter groenewald]

I book the car at people doing wiring and computer boxes so hope it will be fixed after this otherwise I must take it to fiat

 

[Pieter groenewald]

Do u guys think that It can be the computer box (ecu) that's broken ??? And can the ecu be repiared or must it be replaced ?

 

[Peter Pick-Up]

That's very unlikely, but anything can be fixed...

 

[Pieter groenewald]

That's very unlikely, but anything can be fixed...

Peter what do u think can be the problem ?
