Hi all maybe u can help. I've got an uno turbo 1372 ie. Car doesn't want to start. Installed a new computer box and airflow metre thinking they are faulty. Did check all wiring as given in diagrame and all seems fine. Please help! Did check if injectors are giving a pule and it isn't pulsing. Don't know what to do nor how to fix it.

Check for spark.

If no spark and injectors not firing, will almost certainly be the TDC (aka crank) sensor.

Hi Fingers99

Thanx for the reply!

We did check. Spark is there but injectors isn't pulsing. Seems that there is no signal going to the injectors, do you think that can still be caused by the sensor.

Thanx Bernadette

No.

Best guess -- and I've no experience of Uno Tubs -- is a wiring issue of some description.

I think the Punto GT has a similar ECU & etc. Might be worthwhile cross posting there (or PM a moderator) as there are not that many Uno Tubs here.

did you check for a pulse with a digital meter as these wont register the pulse as they aint quick enough to register the voltage change check with a dial one or maybe if you have another fuel rail connect it up see if it letting fuel through has it been stood for a while cause injectors can sieze if left mine were or check the plugs are wet with fuel and is the fuel pump working can you hear it from the rear of car near the fuel tank

Hi guys, thanx for the replies. Managed to sort out the problem. Wiring on the fuel pump relay and injector relay was the same as the Haynes manual but yet did not work. Sourced another signal cable to the injector relay. Seems to have sorted out the problem.

Regards
