Ford transit will not start when warm

[salvatoreguzman]

Sal från Sweden here.

I have a housecar that i built on a Ford Transit Turbo 2,5 lit. 1993

Now I have a huge problem with it.

When it is cold or has stood unused over winter it start right away. No problem, but
When it is warm and i have been driving for och while and I stop at a petrolstation It will not start.
I have a trick then, i grind it and pump the accelerator Sometimes it starts but if i have bad battery it will not.

I think I have a electronic fuelpump. I have no underpressure in the tank. Was before.

Please help me.

Sal
