Today my 924 died at a gas station, ran great before but when i went to start it after fueling it would stumble and run like absolute garbage but at higher rpm it would run fine.

After some investigation i found the fuel pump relay was repeatedly turning on and off at rpm below 2500. Causing the crap idle. Then it just stopped working all together
No fuel pump no stumbling, nothing.
After manualy powering the fuel pump, and checking if fuel is at the injectors the car still doesnt start or even stumble

I think it might be the pickup in the distributor causing the relay to not engage and it to not have spark but idk

Anyone have similar issues?

Sounds like you might know where the issue is.

Check the LT voltage at the coil - 12v
Then check the coil is working by popping a spark plug on the end that goes the distributor cap
Then put back together and check for a spark at one of the plugs
If no spark then likely it's the condenser/contact or CIS if later.
