while driving my van it died on me. i tried to restart it but it just turns over. after looking at it i found out that there is no spark coming out of the coil pack. so i changed the coil pack but it still wont start. so next i changed both the cam sensor and the crank sensor. but it still wont start so i changed the computer that was under the dash board but it still wont start. the fuel pump is pumping but after changing all the sensors and the computer. i have also changed the ignition switch. it still is not getting spark from to the plugs and the plugs and wires were new two weeks before the car quit running.
