vechile only runs rough for approx. 30-450seconds then will run fine?

Check for vacuum leaks. Make sure the EGR is working smoothly and not carboned. If the check engine light has come on, have the computer scanned. Most parts stores will do it for free.

there are no codes in obd,thoght possible coil or fuel pump pressure? pump is noisy

If the pump is noisy, you could be right. Actually, check fuel pump pressure and fuel pressure drop off. When you shut the key, it should hold pressure for some time. If it drops quickly, there is either a leak in the fuel system, a leaking injector, or the pump is allowing it to back feed.

MIGHT WANNA LOOK FOR MOISTURE UNDER THE DISTRIBUTOR CAP TOO
