on the 1995's do they still have the Ds4 injection pumps? so you can't turn them up?

95 has a DS4 pump. You can turn them up but it has to be done through the ecm.

I turned up the screw yesterday and right when it started it ran away. I had to cut the fuel line to stop it. (Tried chocking it with a towel but didn't work). I turned the screw back down and now it won't start.

Can anyone help me with that? Is there supposed to be a little spring in the hole were the allen head is. Trucks a 92 6.5
