Technical Error Codes undefined

I have punto 55 with marelli 16f ecu, no start, and gives these error on autoboss scanner without any description, anyone knows these numbers????
7101 Undefined DTC
717 Code not received attention
727 Code not received memory


other sensors and coils seems ok when testing, also replaced the crank sensor with no luck.

Never used that scanner. IAW Scan 2 is free and covers that ECU.

The car doesn't start. Is there a spark? Is there fuel (you should see a dribble of petrol onto the throttle butterfly when cranked).

Has any part of the car been removed before the problem occured? I ask this because the most common cause of non starting after a rebuild is failing to put the pip on the crank pulley into the hole in the alternator pulley after replacing the cam belt. In this case, you get fuel and spark, but the spark is 60 or 120 degrees out.

No one changed anything, can this pip fallout and what it looks like cuz it looks like a big pulley like a gear with teeth s ? There is fuel but no spark, thanks

No. Pip is for location only. In theory it can be removed altogether and providing everything is lined up. the timing will be right.

No spark on any of the plugs? Check for 12v to coils.
