Jeep Grand Cheroke 98 Problem that turns off

I had the problem of the mastana the jeep did not want to turn on. I put the scanner and had some sensors given to them, now the Jeep turns on and turns off, and changed the coil, the espares, the gas bonba, the Jeep on with a fault of Espare but they are new !! stinks of gas, I need to change the module of ignition .. and I am thinking that it is the computer !!!! Someone who can help me !!! I'm going to thank

Did you make sure to correctly place the spark plug wires? What sensors did you change?
