Hi,
Just joined site today and was hoping someone may be able to help me with my Seicento 899 Spi 1999.
I took it for a drive and was sitting in traffic and the radiator fan came on. This was all fine as the engine didnt overheat and I got to my destination. Re-started the engine and came home absolutely fine. Went to use the car a week later, it started and chugged really badly with black smoke from the exhaust. Normally it revs up when starting from cold and then settles down.
I checked the plugs and they were all black as though the engine was getting too much fuel and not enough air. The air filter is clean and there was no obstruction in the piping. I took the top off the Spi unit and there was fuel entering the throttle body as normal. After trying to rev the engine hoping there may be a blockage let the engine idle, then I heard a popping noise coming from the injector/throttle body, the fuel stopped flowing and now it wont start at all! Only when you release the ignition key you get a spray of fuel from the injector. I removed the fuel inlet pipe from the side of the Spi and fuel comes through from the pump on turning the key. The plugs are wet but the engine just doesnt fire!
If anyone could help would be very greatful. Many thanks in advance!
