No spark

I have a 1987 Audi 200 C3 with the MC2 (2.2 turbo 10v), and I’m dealing with a no-spark issue that seems related to the fuel pump not running. Car was working fine in march, then it was left for 1 week and after that tried to start it again, didn't have any spark.

Symptoms:

• Engine cranks normally
• No spark at all
• Fuel pump does NOT run when ignition is turned on or after cranking it.
• If I manually bridge the fuel pump relay, the pump runs fine, still no spark.

What I’ve checked/replaced so far:

• New spark plugs
• New spark plug wires
• Battery is good
• Ignition coil has +12V
• Distributor (cap/rotor) is OK
• Hall sensor was checked by electric, so should be good
• Grounds seem good
• Fuses are all good
• ECU has power

What could be the issue?
