97 sebring conv wont start

I have a 1997 convertable that one day just stop starting.
It turns over but won't start. It has no spark. We replaced the distributor, still wouldn't start. Then we replaced the engine computer still nothing ( it is the right computer, I matched the numbers up). Then we replaced the crank position sensor, still no start or no spark. What else could it be? We also checked all the fuses and fusible links, all look good. It wont even start with starting fluid.HELP ASAP

i have the exact same problem with a 98 convertable. I even replaced the distributor and fuel pump and filter. still no start. you might check the auto shutoff relay under the hood. a chrylser mechanic told me that they need cleaned sometimes and it keeps it from starting. you can swap it with one next to it, they are identical. look on the bottom of the cap and figure out which one it is and swap it with the one next to it, there should be four of them. did not work for me but maybe you will get lucky.
