2005 3.3 stalls, re-starts but now won't start. No codes stored
 

The car started stalling a few days ago, but would re-start after a few minutes. would then run fine, but would later do the same. now, it will not start. I pulled codes, but nothing was stored. Coil good, testing cam & crank sensors, but could be fuel or PCM. I can hear fuel pump whine on key on before start, but may be filter/fuel pressure issue. Help!

Just a quick check for you before progressing, check for burnt wiring near exhaust then come back on..
