CPI is central port injection. That's the type of injection system the vehicle is equipped with. Since you are on Oahu, I assume when you say cold start, you just mean when the engine has had plenty of time to cool off. I can't imagine it gets very cold on Oahu. Have the air/fuel mixture checked. From the smoking it sounds like you might be getting too much fuel. That could cause smoke when the excess fuel burns. Have a compression test done on the engine also. You could be losing compression. If you are, then it is probably a cylinder head gasket, which could be allowing oil and/or coolant into the combustion chamber. When either one of these fluids burns, it would cause smoking also. A loss of compression would also cause problems with the engine starting. If it's not a big loss in compression, then the engine wouldn't have too much trouble starting up once it's warmed up a bit because the seals and gaskets would have expanded and given you back some of the compression it had lost. Just be sure to always let your engine warm up for a couple of minutes(now and after the problem is fixed) so that your seals and gaskets are able to expand before taking off. Otherwise, you could be putting everything under too much pressure. Hope that helps.
