dying at idle

[ladenblowfish]

Hey guys, after I've my car for a while and I cut it off, when I recrank it, it shudders and stumbles and most of the time it dies. When I crank it again I runs fine. Any other time its runs perfect. I've ran some seafoam through before with no change. Full tune up- plugs, wires, pcv, coils, fuel and air filters, both O2s. No check engine light. I was thinking fuel pressure regulator or maybe coolant temp sensor? Any other ideas?

IAC valve, fuel pump, crank sensor, cam sensor, all possibilities.

I would change the fuel pump, sounds like the culprit.

If it was the IAC, cam or crank sensors make the check engine light come on?
