Civic 07 hybrid dont start ( u1204 u100)

its a 07 civic hybrid with 272 xxx miles.
About 3 weeks ago i was driving and the engine died, i turn on again and its drove until 12/31/2019 when i was driving and died again, but, at this time, dont turn on. I had to wait 40 minutes, drove 5 minutes and died again. I thought that the problem was the fuel pump, changed it and let the car parked and running about 30 minutes without issues, after 1 minute driving the car shut off and dont turn on. After 2 hours i tryed a couple of times and this thing turn on again, about 40 seconds later, turn off... Next day the car turns on but after 5 seconds turn off... And now, the engine dont crank. Fuses at engine and dash are ok. When i try turn on i can listen a "click" coming from the engine fuse box (like a relay)... When the car was running i got the following codes:

​​​​​​U 1204
U 0100


Any suggestions ?

...google your codes.

They tell you what to look at, and it's not fuel related, so not sure why you replaced the pump.
