Mine started with sputtering. Then just finally quit starting all together after a couple weeks of chasing my tail. What was throwing me off in my situation was the fuel pressure at the rail with car not running but key on was zero. New pump, regulator, cps, and still zero at the rail. Thankfully, I stumbled on the icv making noise. I swapped in a new one and had the normal 3.8 bar at the rail. I didn't think the ICV was THAT involved in fuel control. Its a simple 2 wire plug, so not sure what the ecu 'sees' from it. So to double check, I swapped the old ICV in and sure enough zero pressure at the rail again.
