My son started the van yesterday morning and while giving the engine a moment to settle put on his seat belt and turned on the headlights. As soon as the lights went on the engine died.
Now, we have the following symptoms:
Engine cranks but does not start. I get oil pressure but no indication of fuel (flooding) or spark.
I don't hear the fuel pump when I turn on the ignition.
The headlights and parking lights do not work, but brake lights and
4-way flashers do.
The radio, power mirrors, and dome lights do not work.
I've taken apart and re-made the ground connections near the battery and checked all the fuses in the fuse box.
Is there any single point failure that will explain the combination of things that don't work? Suggestions for troubleshooting? Anything else?
Thank you much.

Okay, I've had the chance to do some troubleshooting. Please see my original post below for background...
With the ignition switch in the ON position, I used a voltmeter to verify that several fuses under the dash were not getting power. One of the two ECM circuits, the horn circuit, etc., consistent with the pattern of things that aren't working and with failure of fusible link C.
I took out the battery so I could get to the fusible lnks.
The four fusible links come out of a watertight connector and are spliced to large red wires that disappear into the main wiring harness. All four of them have "2.0 SQ. MM FUSIBLE LINK" printed on their insulation and they're sort of light tan. (It's hard to see the color in the dim light with a flashlight.)
I parted the connector so I could look at the terminals. The spades in the part on the firewall are all pristine. I checked continuity between them and the battery cable terminal and they're all good.
The holes surrounding links C and D are both partially melted from heat and the terminals discolored by the melted plastic.
I took resistance readings from the terminal of link C in the connector to the fuse box, with the ignition switch in the OFF position.
The left hand column of fuses is a direct connection to fusible link C, at about .16 Ohms, and again correspond to the circuits that are effected.
The second column of fuses reads about 4 ohms.
The rest of the fuses are not connected, or at least greater than 200 ohms, which was the scale I was on.
Is that what I'm supposed to see? Which would suggest to me that the immediate cause of my electrical failure is the CONNECTOR?
Any thoughts as to what should I do now?
Thank you.
