Hello i got a kia sephia 1999 and wont start i change the fuel pump and nothing the fuel pump is not getting no power i turn the key on and nothing can you please helpe me find maybe was the problem i dont know what to do

Look in the fuel pump/filter area?

Make sure it's in park, or neutral if manual tranny. Make sure battery connections are tight and clean. Check starter relay and check ignition switch electrical portion to ensure it's getting current from the battery to the relay.

It sounds like you may have a sticking electric fuel pump. Next time this happens have a spray can of starting fluid in the car and spray it into the intake air hose of the engine, if it starts you have a fuel pump problem or loss of power to the pump from a possible bad relay or control.

sorry to tell you but you have a blown headgasket or cracked cylinder head. that is why the coolant blows out of the radiator and the engine won't start due to engine compression getting into the cooling system.

Broken timing belt?

You're fuel injectors may be clogged.

Ok it sound like its your fuel pump but i would start with the fule pump fuse and filter first than if it still doing the same thing then change the pump.

I have a KIa Sephia 1999, and I replaced the fuel pump but when to try of starting the car dosen' t turn on

a cut off switch is almost never the problem just hummor me for a second and please check that the fuel filter is installed correctly not backwards then check the fuel pump fuse and relay if all good check for power at the pump and a good ground if all this is good then the pump need replacement

I would say it sounds exactly like a passlock problem. There is a detailed write-up here: http://newrockies.ca . The guy is great, this was the only way I was able to save my Park Avenue.
