Hi: This is my second message to this board. After shutting the engine off, after 20 minutes, it is impossible to restart my car... I have to wait until it cools down completely. I have checked the electric circuitry, all wires / igniter / distributor are ok. I have changed the fuel pressure valve, since we thought we had vapor block.
I am running out of ideas. If fuel and sparks are all right... what is missing? Air? Is there a special air source I have to check that may run or not when the motor is hot? Can I still have vapor block in the gas conduit coming from the tank?
