Technical No fuel comin thru? mk2 uno start

[Alex22]

Yes my uno "start" won't start lol!

i was driving on dual carriageway when suddenly i had no use of the throttle, the engine just slowed and slowed and now the thing won't start

the timing belt is correct and there is spark, but apparently no fuel....
confused

if the fuel pumps in the same place as a uno turbo, then check the wiring on the fuel pump under the car on the drivers side just infront of the rear wheel. or turn the key to just before the engine turns over and listen for the pump to "prime up", it'll be a buzzing sound.

failing all that, u might have a blockage? or even ur fuel gauge might be dodgy and be reading fuel there but ur actually empty

Dunc

 

[Alex22]

will check them now dude cheers
errm well it happened just after i'd put in £10 fuel so i doubt it empty

Ok, let's get some facts:

What year is your Uno?

Does it have SPI or Carburetor?

WHEN did the problem occur (i.e.) at night/ daytime/ ever since it's got cold or wet?

Does your airbox have the metal foil pipe connecting it to the exhaust manifold?

Are your spark plugs getting wet when you try and start the car? Can you smell petrol in this situation?

If your Uno is SPI, then it sounds most likely to be fuel starvation. Either your fuel pump has failed or you have a blockage somewhere. This will be confirmed if your spark plugs are dry even though you've continually tried starting the car.

If your Uno is carburetor fed, and this problem has occured in the past week ever since we've had some cold snaps then it could well be carburetor icing. Conditions at night are just perfect at the moment for freezing up a carburetor and causing the symptoms you describe. Thing is, carb icing will go away once the car is brought to a stop and the heatsoak from engine warms the carburetor enough to melt any ice blocking the jets. It will then come back once the car is driven again!

A bit more info. and we should be able to narrow down the problem for you.

L reg so a 92 i think?

SPI

WHEN did the problem occur (i.e.) at night/ daytime/ ever since it's got cold or wet?

early afternoon but i had been driving it all morning and it was running perfectly, having just had headgasket replaced on the weekend (day of break down was a weds)

Does your airbox have the metal foil pipe connecting it to the exhaust manifold?

Yes it does... wassat actually do?

If your Uno is SPI, then it sounds most likely to be fuel starvation. Either your fuel pump has failed or you have a blockage somewhere.

i went and turned the key just a moment ago and there was no buzzing sound from the fuel pump so its not working i take it.
i started the car but it just coughed and died straight away.

Dad has looked at and swapped around fuses and relays and everything worked as it should so it shouldn't be related to those....so maybe a blockage but how can u test a pump failure? and is the pump in the uno the same as in the Cinq sporting?

found the prob... was duff pump ah well
