Use a gage and check fuel pressure. How long since a tune-up. Any applicable codes? Give me a minute on the tranny fluid.

With 4l30-E tranny, there is an overfill screw on bottom of tranny pan. Operate engine for about 3 minutes, loosen overfill screw, if fluid starts coming out, the level should be ok. You add fluid at the same place.

Info shows 42--55 psi fuel pressure. Could be a fuel pump issue? I did ask about tune-up and applicable trouble codes?

Also, check for good voltage and ground at the fuel pump connector.

You can check the fuel pressure regulator and the fuel filter. Don't take any fuel lines loose unless your sure there is no pressure on the system. Once you get hit between the eyes with 50 psi, you don't forget. Btdt
