If it is throttle body injected, average is 20-25 psi. Multi-port injection is 40psi.
Vortec engines such as the 4.3 should be 60psi or more.

SOURCE: 1994 chevy suburban, no fuel coming from fuel

Put an injector noid light at the injector plug terminals to see if your getting a signal from the PCM(computer).If not try to find a computer from the same vehicle that works and swap it into yours to check.A PCM swap will take about 15minutes.

SOURCE: i changed plugs a wires

Your problem is most likely a sensor problem. Did you get a check engine light? It could also be a fuel pump. These vehicles are verry sensitive to even slightly low fuel pressure. Once the pump starts to get tired they just start running crappy followed by stalling and hard starting. Id start testing cheap stuff first. Like the O2 sensor. If it has been a while or never changed then it needs changed. Should be changed every other year or so to keep it working in tip top shape. cheap O2 sensors may have to be replaced more often like once every year. Next I would look at the MAF sensor. These often get a bit dirty inside and affects the ability for it to detect the proper amount of air. Clean it with a MAF safe cleaner and it just might do the trick.

No gas on injector carburator

Well a 95 Chevy Suburban would have fuel injection, so no carb. Have you checked fuel pressure, and do you have power and a ground signal going to the injectors ?

200 Chevy Suburban -- trouble starting

Bad fuel pressure regulator. Located on drivers side of engine on fuel rail. Cost of part is around $70. Easy to replace. Buy the part, look at it, find the old one on the engine in the area described above. Pull the vacuum line off of it, if you see any fuel in the vacuum line it's bad. The vacuum line sucks up the fuel flooding the engine. Classic symptoms. Make sure to relieve the fuel pressure prior to removing or let it sit for a couple of hours, or over night. The leak will relieve the pressure over time. Simple clip holds it on, easy to get at. Make sure to remove both "O" rings prior to putting new unit on. Should solve the problem.
