Will not start after fuel pump change

I have this van that was not having any problems but suddenly I blew a rear brake line, so I parked it in my yard.

The next day I started it, moved it forward away from my tool boxes and let it idle while I crawled underneath to verify place of brake leak.

As I was under fuel tank I heard the fuel pump intermittently stop running and it stalled. I got up and tried to restart and it would not. So I continued with dropping fuel tank and replaced brake line and replaced fuel tank.

I had it open from inside because in January I replace fuel pump and made a access hole inside van. So I verified fuel pump power and fuel pump was not running and every once in a while it would run and start the van.

Also, if I sprayed starting fluid in air cleaner it would start momentarily.

So mean while the Amazon dealer was mailing me a replacement fuel pump, so today I replaced fuel pump and you can hear it run every time you try to start the way it should.

I verified fuel from fuel rail at engine and I verified spark by a strobe timing light. But it will not start not even with starting fluid,

Does not even try, turn it over and over and still no start. I am dumb founded by a traveling problem.
