Alfa romeo 1991 164s
again !?!
She turned on for about a week , yet 3 days ago she stopped

Im leaving work and again the starter is working but the engine isn't starting
I put in the gallon of gas thinking that was it (nope)

Since then I tested the fuel pump its working only with direct current
And the main coil has power on both sides
Also changed the crankshaft position sensor
And both relays next to the coil (112,113)
Swapped both computers with the ones from my parts car a 1991 164l
Oh then my radio I put from my parts car also stopped.working

You say the fuel pump works only with direct current. I am assuming that means you are feeding the pump 12V directly, not that you are using 12v DC as opposed to AC. Sounds like a bad fuel pump relay. Should be that one by the left headlight with the red stripe through it.
