92 acclaim start problem

my 92 acclaim has a problem with starting. it won't start easily in the
morning or whenever I leave the car not using for more than 6 to 12
hours.

everything looks okay, but it takes me to start this car more than 5
minutes.
once it gets started, it exhausts smoke for a short time.
and after starting, the problem's gone as long as I don't leave the car
not using for certain time.

so, during the day time, because I keep driving it, the engine starts
very well, but after I came back home, leave the car at the parking
lot, then next morning the problem comes back.

I tried using starting fluid but it wouldn't help.
When I turn the key, check engine signal blinks 5 times and short pause
and then 5 times again. Does this mean something? I heard it could be
map sensor but I have no idea because I am no mechanic.

Can anyone help me on this problem please?
