1999 b2500 low fuel pressure
I have a 1999 b2500 that is hard to start and backfires through the intake. I'm trying to narrow it down between a fuel pump or injectors. I already swapped the relays and no improvement. I am getting only 20 psi at the rail running and not running. It will not hold pressure when you turn the key off. I'm thinking pump really, but I want to be sure as most of you know, money doesnt come easy. Any help is greatly appreciated

Yes, it will be the pump.
Heads up on cheaper pumps, they do have warranties and they do honor them, but better to get a good pump(motorcraft) than to have to swap out cheaper pump in 6 months.
Yes, electric motors tend to fail as "no start", but that is just the motor part, the pump impeller could be loose on the shaft or there is a crack in the lift line inside the tank so fuel is just spraying out inside the tank.
Lifting the bed up or back is often the easier way to change pumps
