Fiat Seicento 900 (1999) - Injection Light Flashing, Engine Spins but Won't Start

Hello,

I have a Seicento 900 year 99 petrol only, and have been trying to get it fixed for a while. But maybe from the beginning.

Some time ago my V-belt started to squeak, so I replaced it with a new one. However, after the replacement, it turned out that it still squeals and was probably not stretched too well. After better stretching, he fired, I managed to drive maybe 100 meters and the car went out. I can't get it running since then.

After switching the ignition on, you can hear about 2 seconds of "hum" from the engine (I suppose it is turning on the fuel pump). When I try to start it, the engine spins but does not start and the injection light starts flashing (it flashes all the time the engine spins).

After connecting to the computer (IAW 16FM.EC) and checking the IAW Scan 2 program, the following errors appear:

MISTAKES:
Lambda probe [Z]
Battery voltage Below MIN [Z]
Injector Break [Z]
Shaft position sensor [Z]
CODE control unit unprogrammed FIAT CODE [A]

but after cleaning them, only:

MISTAKES:
CODE control unit unprogrammed FIAT CODE [A]

Please help. Best regards.

I have exactly the same problem: / except that the light comes on after turning the ignition switch and goes out after a while.

This indicator (when it comes to the injection control, the so-called "carrot") is supposed to work like this, after turning the key it should light up for a few seconds and go out, at this time you should also hear the pump working.
Of course, the indicator "works" like this if there are no errors stored in the central unit.

When replacing the belt, you had to physically remove the shaft position sensor. Check its mounting - distance from the speech wheel and whether you have damaged it during disassembly. You can measure it with a multimeter after unbuttoning the ankle (below the expansion tank

I replaced the sensor with a new one, but it didn't help.
