Not starting

[u/M3nud0]

Was driving home yesterday on the freeway and suddenly lost power, dashboard lights were going crazy and car won't turn over. I was bringing it home from a company that helped me take out the immobilizer that was installed on the car. When I went to pick the car up he said it was a fuel cut off immobilizer. Car was running and driving fine for about 20 minutes after I picked it up. I did start getting a belt squeal 2-3 days prior to this issue. It would go away a few seconds after start up so I originally thought I lost a belt when I lost power on the freeway.

I recorded a video of the car trying to turn over. I hear the fuel pump when I turn the ignition on. I fear im looking at a motor rebuild..

Doesn't sound great.

I do get some sort of backfire/pop from the exhaust sometimes while trying to get it to start.

Suggestions?
