    My 98 3.8L sat out in the rain for 2 days and afterwards will not start. At first I thought it was the pump relay located in the command control module. I replaced that module to no avail. I think that the PCM is shutting off the fuel because the pump does not prime and the dashboard theft light is flashing as it cranks. Has anyone had experience with this problem? I checked the fuel pump fuse and it is good. Any help is appreciated. Thanks

    I found the problem. After replacing the CCRM control box, I tried to start it with a standard non-chipped key because I had lost my chipped key. After finding that key, it started right up. So it was the CCRM control box that was the culprit. It houses the fuel pump relay and the PCM relay (and others). It is located in the passenger side wheel well behind the splash shield. The flashing theft light on the dash indicated that there was no communication between the PCM and the fuel pump relay. It is running great again. Evidently the rain had nothing to do with it.
