I don't know if this helps any, I am only a backyard mechanic on my own vehicles(which isn't much) but your problem sounds like it maybe something electrical. A good thing for anyone to remember is that in order for an engine to run you need, air, fuel and spark. Injectors?, computer?, bad plug wires or plugs?...being fuel injected it only narrows it down to a million more things it could possibly be. Are there any noises coming from your engine that's outta place....squeals?.....possibly could be your timing or something that controls timing, make sure your spark plugs are delivering spark or change them if you need to.... hard to say exactly without being there seeing and hearing whats going on but I hope this gets ya started! Cheers :)

The 3.4 liter V6 engine in a 1998 Oldsmobile Silhouette has a timing CHAIN
the engine has not been timed correctly
The timing chain is designed to last the life of the engine unlike a timing belt.
The distributor in a 307 Oldsmobile engine rotates in a clockwise direction. This is common for many General Motors engines from that era. Proper timing and alignment are crucial for optimal engine performance, so ensuring the distributor is set up correctly is important during installation or maintenance.

In a 2000 Oldsmobile Alero : Both the 2.4 litre four cylinder engine and the 3.4 litre V6 engine have a timing CHAIN
It has a chain and not a timing belt. No maintenance required.
It retards the timing so the engine is easier to start. After it starts, it advances the timing back to an advanced position for best engine performance.
getting the marks aligned correctly is important to insure the amount of power you will have.
Valve timing is not adjustable on a stock engine. The timing chain is either installer correctly or not.
1st you have to repalce the timing chaing and gears. Then, you can set the timing correctly.
