We got this little KIA for a great deal with only 102k miles on it. Probably put less than 1k miles on it before the radiator split open on top, and it quit. (We were driving on the highway with cruise control on)
We replaced the radiator, and we guessed that the head gasket would need replaced also. Took it all apart, and sure enough, there was some rust and gunk in the cylinders, so we bought a gasket kit and replaced all the gaskets. This took place over a couple of months, as we found time to work on it. By now it has been about 6 months since it last ran, and we can't get it to start! It cranks just fine, and fires once in a while, but just can't quite get enough "oomph" to actually run.
We theorized that since it's been 6 months, maybe the gas was bad, so we emptied the tank as much as we could, and added 4-5 gallons of high-octane. Checked all the plugs, and we're getting spark... Double-checked the timing belt, it's aligned. Pulled a bunch of fuses and put them back in, and all of a sudden it almost would start! (Firing somewhat rhythmically)
After cranking for a while, now it's basically back to where it was, just cranking and cranking, with a little half-hearted attempt once in a while. Any suggestions?
