Is the MIL indicating and prior to replacement of the parts concerned, was there any trouble codes?

Did you test the fuel pressure before and after replacement of fuel pump?

No I did not because I could not see anything except advertisements on the links you provided.

What do you mean by expired parts? Never heard of the term for automobile parts.

The video is of no help because it is taking me more than 2 hours to donw load and hangs.

Seems the injectors are not firing or you have a fuel pressure problem. Test the fuel pressure first. Perform a leak don pressure test to ensure that there are no leakages within the system.

Have you checked for trouble codes?
