I have a ef hatch with a d16y8 swap with a chipped p28 ecu, the other day I was merging on to the high way and when I stepped on the gas my car completely shut off and died. I checked under the hood and noticed my battery fused was blown I replaced it and it ran enough to get me home. The next day I went to turn it on and notice the lights was dim so I pulled the terminal off the battery and the car died needless to say I replaced the alternator after replacing that I turned it on and boom limp mode, I noticed the fuel injectors for cylinder 3-4 are not pulsing while the car is idling, I already replaced a bunch of fuses, fuel pump and tried other ecu’s and nothing is working, ohh and another thing the ecu I was running doesn’t prime the fuel pump and theres no check engine light when I turn the key, I’m assuming the alternator was loose and spiked the voltage and killed my ecu? any help will do!

Was the swap stable? As in it's been running fine for a few weeks/months?

-with that many issues, dim lights, missing injector pulse, a blown master fuse, other, I'd look through the wiring harness.

it sounds like something is short circuiting, drawing too much current and blowing the fuse.
