SOURCE: 1992 buick century 3.3 what should the fuel injector ohms be reading or the voltage should be reading. i checked mine 4 of them are reading in the 20s voltage

Ohms should read 11 to 15 at the injector pins. Power at the plug should be battery voltage. 12.5 with key on. Use a noid light to see if the injector wires/PCM is firing the injectors. the light should flash when cranking the engine over.

My buick century 1992 starts. it runs for awhile then shuts off. I had replace the plugs and wires and the temp gauge is find. what could be the problem?

This could be several things and this forum cannot support the multiple possibilities, however, I would check the following in this order:
1. Fuel pressure
2. Ignition system
3. Battery voltage under load.
4. Fuel filter
5. Any GM lockout or security systems

I know this is somewhat vague, but there are many, many potential causes.

I hope this helps:)

No injection pulse

looking at the schematics, well the PCM controls the pulse width to the injectors , BUT , there is a injector coil fuse , its #2 in your kick panel fuse box , a 20 amp , check it , sure hope that fix ya . that would be sweet .

1992 Buick Century won't start sometimes but has spark in the plugs.

Faulty cam sensor maybe - it controls the injectors. To diagnose, when you get a non-start, spray a V.small squirt of easy-start(ether) and if it runs a little then you have a fuel issue. The spark timing is controlled by the crankshaft sensor so that can be faulty and cause a mistimed spark but usually you'll get a mis-fire in those cases.
