Answer
Hello and thanks for the question...I'll try to help.
It sounds like the cylinder head gasket is blown. Check the coolant level and also check the fuel pressure regulator......to make sure that isn't blown. Remove the vacuum line and turn the ignition key to run......see if fuel pumps up through the vacuum nipple.
Hope this helps,
Erik
