2000 Chrysler Cirrus CAR WONT START

Electrical problem
2000 Chrysler Cirrus 6 cyl Front Wheel Drive Automatic 48.000 miles

I HAVE A 2000 CIRRUS I WONT START. TOOK IT THE DEALER THEY PUT I NEW CRANK SENSOR, THEY ALSO PUT A PCM COMPUTER IN IT THE CAR STILL WILL NOT START. IM NOT GETTING ANY SPARK. IM GETTING FUEL. I NOTICE THAT WHEN I TURN THE KEY THE OIL LIGHT COMES ON WHICH IS TELLING ME THAT MY PCM IS GETTING A SIGNAL. IM NOT GETTING ANY JUICE TO MY DISTRIBUTER. AND THE DISTRIBUTER IS ALSO BRAND NEW. IM NOT SURE IF THE PCM CONTROLS THE SPARK OR IF THERES IS A ECU THAT CONTROLS THE SPARK. I REPLACED EVERYTHING IN THE EGNITION SYSTEM AND THE CAR STILL WILL NOT START. SO MY QUESTION IS WHAT CAN BE WRONG WITH IT PLEASE LET ME KNOW ANYTHING THAT MIGHT HELP ME OUT THANK YOU.
