ENGINE WILL NOT START

Engine Performance problem
1995 Oldsmobile Silhouette 6 cyl Two Wheel Drive Automatic 295232 miles

No spark, no fuel. Coil pack not the problem. Tried 2 others with negative results. What could be the problem? I have checked all the fuses and they are all good. No fuel, no spark!

Hello, you might check for an rpm signal. Without that signal you won't have any spark at the plugs or injector pulse. Because there is an oil pressure switch in the fuel pump circuit, once you crank it enough to build oil pressure and the switch closes, the fuel pump will run even without an rpm signal, but, without spark and injector pulse, fuel pressure won't help.

You might check the circuits at the crank sensor.
