99 Suburban Won't Start
UPDATE: It was my fuel pump. Truck is running now.
The truck gets fuel and you can hear the fuel pump come on and go off. If you bleed the fuel line, gas comes out but it's like a trickle. The dash lights that are on are Check Gauges, Service Engine, and the battery icon. I get the following code
P0304.
Any ideas before I have to start buying a bunch of parts that don't help fix the issue?

It turns over. The guy poured gas in the mod (carburetor looking thing) and it starts for a few seconds then cuts off. I've had 3 people look at it and they are saying fuel pump needs replacing but they all said they can hear it come on and go off.

Correct - for my 93 the failed icm shut down the throttle body injectors. Pump ran but no injector operation. Don't know if a 99 has same unit in distributor but it's an easy part to change, not overly expensive and commonly fails.
