87 GT 2.8__When I go to start the car in the morning it starts before the engine turns over twice, which is great but after I driver it and it has time to warm up it takes several seconds to start and then blows a big puff of blue smoke when it starts. Any suggestions ?

Many 2.8s have leaky valve guide seals. The result is a puff of smoke when you start it up.

Your cold start injector is working well. When the engine is warm it will not work and it will take longer to start the car.

Also could be that the cold start injector is leaking and allowing fuel to blead into the engine after shutdown basically flooding it. When you try to start it hot it's flooded and then blows a bunch of smoke until it burns out all the raw gas. Larry

Cold start is coolant temp dependent and ONLY when starter is on.
Switch Close when coolant temp below ~95°F.
Coolant is warmer then On time goes down, max time is 8 second at 20°F coolant temp.

Likely black to drk gry smoke...
Blue usually mean burning oil.
