1994 Dodge Dakota please help

What led you to the fuel pump and ignition coil? How did both of them fail at the same time? What symptoms are you trying to solve?

We need to start with how the system works, but I'm racing a dying laptop battery. I may have to come back tomorrow.

The fuel pump will run for one second after you turn on the ignition switch, and you should hear the hum. If you do, the pump is okay. Start with the basics by checking for spark. If that is missing, the fuel pump most likely won't run either during engine cranking. The fuel pump and ignition systems have the crankshaft position sensor and camshaft position sensor in common. Those account for the majority of the no-start problems.

Have you checked for diagnostic fault codes yet? Chrysler makes doing that yourself much easier than any other manufacturer. Cycle the ignition switch three times from "off" to "run" within five seconds, then count the flashes of the Check Engine light. There will be a series of flashes for the first digit, a short pause, another series of flashes for the second digit, then a longer pause, then the next code if there is one. There's a link on this site to how to do that too, and the descriptions.

That light is run by the Engine Computer, but failure is very rare. Most commonly you'll find a blown fuse or fuse link wire. If you have fuse link wires, they'll be in a bundle near the under-hood fuse box. I think they got away from them by '94. Check the fuses under the hood first, and look for anything else that doesn't work.
