Help! T3 starting issue

[nikp6]

Hi everyone

Novice here asking for advice

My 1985 1.9 petrol has been running absolutely fine and now suddenly wont start

I carried out some of the checks mentioned in these forums -

Jam jar test from the fuel pump to the carb is empty - no fuel coming out from the fuel pump

Cap of petrol down the throat of the carb and it starts straight away, burns the fuel off then dies

I've check the fuel filter coming out of the fuel tank and it looks clear

I've this morning changed the fuel pump thinking that was probably the issue but still nothing - fuel still isn't leaving the fuel pump and going into the carb

What would be the next thing for me to check/change? The fuel lines all look fine to my untrained eye and the guy I bought it off just over a year ago told me he'd recently changed them all

Any advice would be appreciated. In the end I'll take it to the garage but would be a shame if its something simple

Thank you!

Fuels run back the the tank, should start with a bit of cranking or manually fill the carb float and the fuel pump to help prime better

Did you change the push rod for the fuel pump at the same time as changing the pump? Must be 100mm long .
