2001 GMC Sonoma Questions

Just changed the fuel pump, fuel filter, and flushed radiator. Ran fine for a day then this. Checked vacuum lines and they are fine check engine light on as well.

no error codes. no check engine light. blew the head gasket at 199,000. a friend installed new head, lifters, gasket, cylinder #2. doesn't start very good either.

Can the cold start be disconnected without harming engine of a 13 year old sonomq pickup?
I have added a bottle of heat to a full tank of gas and the engine still makes chugging sound when started and some what after it warms up.
