I am working on a 95 5.2 grand cherokee. The jeep fires then dies right away like you turned key off no sputter just dies. I put a new pcm in,new crank position sensor, temperature sensors, oil pressure switch, new asd relay. don't know where to go next. Any help would be appreciated.

My 98 had a similar issue but it managed to stay running if I went wide open throttle (WOT), even though "running" was a stumbling, bumbling unstable thing. Turned out to be the front oxygen sensor.
