2001 Kia Sportage trouble starting

My Sportage is not running.. It will start(sometimes) and will not stay running. It gave a p1115 code. The following has been changed:
Fuel pump
Fuel filter
Throttle position sensor
Crank sensor
Cam sensor
Temp Sensor
Mass Air Sensor
And it still doesn't work.. Any suggestions would be greatly appreciated

Most probably one of those freak wiring/contact problems as so many have reported....no precise hint at this point, considering all you have already changed. PLease tell of what you have found when it is back on the road...

Thank you for the response. MY father is looking at it. He thinks that it has something to do with the ignition and the fuel pump. When the truck is idling it quits. Will let you know what he finds out, if we get it on the road.
On another note. I know nothing about these vehicles. I bought this one from my brother in law after he replaced all of the above and gave up. Are these decent vehicles or are they like a k car disposeable??

There is no neutral opinion: people like it or hate it.
Those who like it make what it needs to keep it running as the little truck is structurally sturdy with a full frame and they have fun offroading it with monster tires. But it develops multiple annoying problems, and has a trend in developping freak symptoms that have a logic of their own, that is, one you would not think of naturally....like recently, mine lost ground for the left headbeam...right in the socket; 2 days ago, the lining of rear brake shoe detached and blocked the wheel; you will have checl engine light for the ignition almost all of the time and you will know when it really means something: one freak ignition wire and you will go nowhere; front vacuum hubs have a very limited life time specially in cold temperatures; fuel burning is as high as low end torque is low; timing belt at 65000 miles is a must.....but at least this is a non interference engine and it detroys nothing if it lets you go in the middle of nowhere.....and poor contacts/corrosion at sensors and other connectors are a well publicized fact.
.. and there are those who hate it for all of the above...well.....ok for now....so please update the knowledbe base of the community when you find what has gone awry....
