Truck will not start

[James Crow]

I drive a 2001 GMC Sierra 1500 sle Z71 4wd 5.3 with 197k I was leaving work the other day and I lost all power my truck it sounded like a bad exhaust leak mixed with a fluttering sound I’ve replaced the fuel pump, fuel filter and crank sensor, has a new 130V alternator installed earlier this year, optima red top battery, the truck refuses to start and I’m running out of ideas and need help before I take it to a shop and drop a crap load of money into it before school starting next month

Does it have fuel pressure at the rail?

 

Do you have spark at the coils/plugs??

 

Will it run on brake cleaner??

 

Without a scanner hooked up, it's hard to see what all the main sensors are saying.
