2001 156 2.0ts

Not Happy alfa 156 2.0ts will not start and no code key light

2001 2.0ts turns over but will not start.No code key symbol lit.Connect to MES says code u1600, error as Fatal !!
Battery will not hold a charge and have tried to jump start in the past which has always worked.
Car hasnt been used much if at all in last year.I just jump start it or trickle charge just to move around front drive

Search of posts usually has code key light on fault.Mine is opposite??

Car is worth few hundred pounds as spares or repair if that
Is it time for car heaven

Trying with a properly charged battery would be the first thing to do.

Continuously jump starting isn't the greatest idea as it is quite easy to kill ECUs.

U1600 is the Engine ecu isn't receiving the start authorisation from the code box. The code key light on the dash is powered from the immobiliser box under the dash. So most likely the immobiliser box isn't getting power if you don't have the code light on the dash.
I'd start checking the fuses and relays and the plugs to the code box. But as David said make sure you have a properly charged battery for starters.
