OK, that eliminates a whole pile of things. First, make sure that 12 volts is getting to the power module as follows; bypass the ASDM by putting a temporary wire from pin 2 to pin 3 on the ASDM - this will put 12 volts on the power module input and run the in-tank fuel pump any time the key is on, regardless of the other logic inputs to the ASDM. Next, check the 23 volt power supply output. Look on any one of the following places: The center pin of the air flow meter connector, or the pink wire on the throttle position sensor, or pin 3 of the power module. There should be 23 volts on the above points. Be very sure not to short the 23 volts to ground - that is the most common failure point in these cars, and the most easily caused by poking around the system. If the voltage is not 23 volts within about 1/2 volt or so, your power module has failed and we'll have to find you a new one. If there is 23 volts at the power module output, turn the key off and then short the wire which goes to the fuel pressure switch to ground, then turn the key on again momentarily, while you watch the voltage on the control fuel pump input - you should see a momentary surge of 12 volts or so on that point, and there should be a spurt of gas from the nozzles. If there is a momentary surge of 12 volts on the control fuel pump, but still no gas at the nozzles, we need to check the fuel pressure at the control fuel pump inlet. It should be 13 PSI, within 1/2 PSI or so. The easy place to check this is at the filter outlet under the car, just under the passenger door hinge post. If there is still no drive to the control fuel pump, we'll have to investigate the power module amplifier function and the logic which controls it, but let's not get too far ahead of the story.

I took the air cleaner lid off, poured a little gas down the throttle plates, put lid back on, car started, ran for a second, and died. So it seems the problem is lack of fuel. Any and all suggestions are welcome and greatly appreciated.
