If your 1990 Buick Riviera cranks but doesn't start, the issue could be related to fuel delivery, spark, or ignition timing. First, check if there's fuel in the tank and that the fuel pump is functioning properly. Next, inspect the spark plugs and ignition system to ensure they are providing a strong spark. If these components are in order, consider issues with the engine's timing or sensors.
Check you battery
An engine which cranks but will not start is not receiving enough fuel or has no spark. A clogged fuel filter or bad spark plugs often cause this problem.
Engine cranks but doesn't start.
The symptom will be no spark. If the problem with the camshaft sensor is intermittent, the engine may stall from time to time. If the failure is "solid," the engine will not start. A pulse from this sensor is required for the engine to run.
Check engine compression Check engine timing
No, The compression test is done as the starter cranks the engine
The engine needs fuel, compression and spark to run, it is missing one of those.

i hit he curb and put a hole in the oil pan ,i replace the oil pan now the engine cranks but doent start. what could be the problem
it could possibly be a bad coil, crank shaft sensor, or cam shaft sensor.
For some reason it is not getting EITHER fuel OR spark , so it cranks but doesn't start
