You have to check for spark and fuel pressure. The 3800 motor can have a bad module (sits right below the coil pack, as well as bad coils. Also check for fuel pressure. I put a brand new dealer pump in a 93 Olds once and it was not putting out enough pressure to engage the injectors. Section 4 in a Hayes manual found at most Advance and Auto zone stores will give you the fuel pressure reading you need.
Hope this helps.

Can you here the fuel pump running?no, check fuse,and pump relay. Check pump fuel pressure,at the fuel injector rail,or throttle body. Check for voltage at the top wiring on the fuel nozzel.While cranking look for pulsating voltage.None, test computer,scan system. let me know the outcome.
