    1982 528e Fuel injectors not firing

    So I have a bad habit of buying broken cars... So 1982 528e 160k miles, sat for over 4 years because of no fuel issue.

    I discovered fuel pump wasn't turning on(broken ground on pump assembly) so replaced and converted to single walboro 255, car now has excellent fuel pressure during cranking. Pump does not seem to prime, only gets power during cranking.

    However still doesn't run, I worked my way up to the fuel injector rail where I discovered both pins are receiving voltage during cranking but I dont think any voltage without cranking.

    tested different injectors but the pin never grounds so it doesn't work.

    I've replaced all 3 relays, including main, fuel etc. Main relay gets 12v from battery.

    Car WILL run on starter fluid confirming that there is spark.


    So what procedure should I attempt to get the fuel injectors to properly fire?

    I'm thinking bad ECU but wouldn't I have spark issue as well?
