1997 chevy suburban 5.7L P0300 code
My truck through a P0300 code the other day and have been trying many things to fix it.
I have tried changing the distributor, plugs and wires.
I have tested the fuel pressure and it was on the low end of what the fuel pressure should be. So I tried changing the fuel filter and fuel pump but still did not fix the issue.
Does anyone have any suggestions on the next steps to take?
Any help would be a appreciated.

Try this
P0300 is a multi cylinder misfire, my blazer done the same. Try changing the rotor button if you havnt and if so check your spark from the coil. It should be blue if its red its weak and will cause it. I would go with rotor button first. I changed cap, wires, and plugs with no change. Once new rotor was insalled it resumed normal function
