No power to fuel pump

It sounds like the fuel pump relay is not working. Here is a guide to help you test it and the location of the relay below:

Because I do not know testing you have done, I have to start from scratch. If the vehicle cranks good but will not start, have a helper crank it, while you visually check for spark at the plugs. Check for possible trouble codes, if you have not already. To check for mil codes, you turn the key just till the dash lights come, no further, cycle the key on--off, on--off, on, then the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes. The information I looked at was Lebaron--3.0 sedan. The ASD relay sends voltage to several circuits including the fuel pump. Did you check voltage and ground for the fuel pump motor at the pump connector? The voltage wire for the pump shows to be dark green with black tracer.

Start by testing the ignition switch and the ASD relay.

The ASD relay is in the engine bay forward of left strut tower. See picture below. I do not know about the computer yet. Check basics before you go there.

What kind of reading did you get from the ASD relay?

Running out of gas will have nothing to do with losing spark. With the key on, do you have power to the positive side of the coil?

Have the computer control of the ASD relay tested.

It is true, fuel pumps are cooled by the fuel in the tank. GM and Chrysler are not noted for burning out a pump on an empty tank, but Ford is notorious for it. We cannot "assume" the coil is good, we need to know. With key on check for power on the positive side of the coil. If yes, check for positive voltage on the negative side. If no, the coil is bad. Next you need to check for injector pulse. This can be done with an "incandescent" test light connected between both terminals of a disconnected injector connector and cranking the engine. You are looking for the light to blink. If no blink, it is either the crankshaft position sensor or the ECM. The coil and injectors get the signal to fire from the ECM and the CPS.

Yes, an "incandescent" test light or an analog volt meter works the best. If you are using a digital meter, it will not respond quickly enough. The "wiggle back and forth" is the needle on an analog meter. The crank shaft position sensor, CPS, tells the ECM when to fire the plugs and the fuel injectors. Also, there is a unit called a "noid light" that is a small zenon bulb that plugs directly into the injector connector and flashes like a timing light. You can get a complete set at most parts stores for about $20.00.
