Problem to start up car without Start Gas!

[JonasGranlund]

Hello!

a few hours ago I stopped my car for 10 minutes, after that I tried to start it but it refuses to start at all.

I bought some start gas and let a friend hold it against the airfilter, then it started immediatly and also died as soon as we removed the start gas.

I think it depends on that the car dont get any gas but I dont understand why, I have looked at the fuse for fuel pump and also for ignition/fuel and both are ok.

Could it be the immobilizer that dont work properly to the key or is the immobilizer going through ignition or will it turn off fuel pump and leave ignition on?

Answer from 9ff in Germany:

We know this kind of starting problems. Most times the reason is a broken fuel pressure hold valve. Its position is inside of the fuel tank in the pressure line 10 cm away from the fuel pump. The car needs it to hold the fuel pressure in the lines between engine and pump. If it is broken the fuel in the lines on top of the engine becomes hot and goes from liquid to gas. Then engine can not start any more before it is cooled down.

Check the valve and let me know.

Hello!

I got help from 9ff to fix my problem, since my car also have been hard to start when it has been warm they adviced me that there is a pressure holding valve in the fuel tank and when that holding valve cant hold the pressure in the fuel line to the engine the fuel will vaporise from the heat when the engine is warm.

After I fixed this problem the engine started immediatly.

Im a really happy camper now :)
