d turbo now wont start

[bufter]

My brother went to the d turb earlier to go and get juice and failed to start, not even a flicker. turns over fine but wont fire. No smoke out the exhaust either. The fuel lights been on for a day but not at the bottom of the guage

I jumped in it yesterday and had to pump the fuel balloon thing 3 times and it went fine...

Once they get low on fuel does it just not prime to the pump? As if i block off the return and pump the balloon, after 3 pumps it gets tight. When I unclamp the return it goes soft again.


Is it just hella low on juice or is the fuel running back somehow?

cheers
