1991 Dodge Dakota no spark

There shouldn't be power to the coil. Did you check for power to the fuel pump? As an alternative, you can check for battery voltage on the two small wires on the back of the alternator or the feed for the injectors.

The secret is the engine must be rotating, (cranking or running) for voltage to appear in these circuits. Voltage will also appear for one to two seconds when you turn on the ignition switch. Most commonly you will have voltage for those first two seconds, and you'll hear the pump run, but there won't be voltage during cranking. That is typical when there's a problem with the crankshaft position sensor.
