My KA has had this problem ever since I replaced a dead injector I had maybe 2-3 months ago. If the car sits over night, it will crank once then fire. If it sits for maybe 5 mins (aka filling up for gas) it will take 2 cranks and then fire. BUT if it sits for maybe 3-5 hours, where it still has a little temp in it, will tank 5 or so cranks then slowly rev, like very slowly rev from 400 to 800-1000, but if I give it gas, I think if I remember correctly, it wants to stall, not positive, but if my memory serves me. Also, this started today, well, at least the first time I noticed a little blue smoke comes out, with the long crank. Car has 115k on it, not beaten THAT much, just some fun maybe once a week if that, 2 "new" kinda injectors. I really have no idea what it could be, but if anyone does, please chime in.

hey dude i had the same problem i got a 93 kade when i first started it it did the same thing but i had 2 dead injectors replaced them and the car still ran like **** still a dead injector so after that bulls**t it was running but a little off u may notice a little shaking from time to time at idle if u have the same problem but it was my lower injector oring.

] to check pull the fuel pump fuse and start the car till it dies. remove the fuel rail with injectors and fuel lines attached. have a friend turn the car to running position DO NOT CRANK look for any fuel spraying bad orings do that and cylinder balance test using injectors and plugs
