Chevrolet Repair: 1999 Tahoe, coolant temperature, fuel filter

Question
I have a 1999 tahoe that becomes very hard to start  after sitting for several days.  I replaces the fuel filter, plugs and wires.  I am getting no codes.  I can verify that I am getting fuel and spark.  

It seems like it gets flooded and takes a long time to clear up.

Answer
Hi Joe,
One possibility is the injectors are dirty, and allowing fuel to just dribble in, rather than spray.
Another possibility is the coolant temperature sender. Read this.
