The key to this is when it won't start to check for spark and injector pulse. Or see if it fires with some small shot of starting fluid.

Re: 2001 Park Avenue 3.8
If it does not start with good fuel pressure @ 40-psi+ and the fuel injectors are firing, I would suspect the CKPS, or ICM as the fault. As mentioned, if it starts with starting fluid, check fuel pressure . Here are some tips for diagnosing ignition (ICM & CKPS) failure. http://easyautodiagnostics.com/gm_ig...n_module_1.php
