i have a 92 full size blazer 5.7
i started it up let it warm up
started to drive to work got about 10 miles it started to lose power then died
this truck has never left me standed before
if i use starting fluid it will start so i have spark
no fuel
checked fuse its good
replaced fuel pump relay no fuel
so i droped the tank put new fuel pump no fuel
so i must have missed something
any help what to check now would be greatly apprecated

Does the relay have battery power on orange power feed?
Can you jumper the gray wire with a fused junmper at relay or inline fuse and get fuel pump to run?
Is the inline fuse getting power to and threw it?

Does the relay click with the key on 2 second prime or power gray fuel pump wire on engine cranking?

Is the fuel pump getting power and ground at fuel pump wiring plugin?
