Hi Richard,
I changed the fuel filter already and also checked distributor cap and
rotor.
One thing I have to say, during wintertime I changed my kingpins and clean
up the complete front suspension , and I must say that the car was standing
in front on 2 axles for about 5 months!!!
so I think that the petrol was at the back of the tank.(Stupid from me I
know).
After remounting the front suspension I put the car in front down and start
the car, it is than that i heard a different noise from the fuelpump!!!!!!

The car can run for 1H30 minutes OK, and than when driving 120KM/h it feels
like the car is on 3 cilinders, like you are loosing power, for a couple of
seconds after this it runs good again.
Yesterday I start the car and when the tachometer is going down to 800/900
TRM the car stops running and the fuelpump was running on /off (a squeeze
noise).

Best regards,
Bart Bonnaerens
