Looks like your getting lots of good feedback here. That code 96 makes me think that this "might" be wired similiar to my 95 Taurus. If thats the case the fuel pump relay is wired to a 3 way splice with with one leg going to the powertrain control module/PCM
& from there to the inertia switch & then to the fuel pump. So if this was a 95 Taurus I would be looking for an open in the yellow wire between the splce & the PCM.

OOPS, i just looked up that 96 code "Fuel pump circuit open, battery to ECA" not "PCM" When you turn the key to run the ECA grounds the fuel pump relay. Is that happening? Strange that you would get that code AND not be able to get the pump running when you provide the ground at the self test connector?

Strange seems to be the norm with this van. I'm not real confident that I made a good connection on the self test connector, I'm going to try again. The fuel pump relay clicks when I turn the key to run just like it does when I ground the self test connector whether or not the relay has power going through it I'm not sure

Yeah, like the other guys mentioned check for power at the inertia switch. Gotta love this forum, i'm learning, you're learning, we are all learning how to fix these miserable/PITA problems.

Do you know if the power is actually getting to the fuel pump connection on top of the fuel tank. We had a 1988 aerostar van that actually did the same type of thing. Fuel pump relay would make noise but the engine would not start. I put in a new fuel pump thinking it was bad, but noticed that the wire connection had corrosion on it (rivet holding connector and wire on fuel pump assembly plate) not allowing voltage to get to the fuel pump itself. Once the connector was corrected the van ran fine. The only way to check this though is to drop the gas tank.
Hope this helps - but hope you don't have to drop your tank to find out.

I don't think power is getting to the fuel pump but, I really hope the problem isn't AT the fuel pump since I filled up the day before this problem started

OK. Bypassed inertia, Power to pump,WHEW!!! Not getting power to inertia & still can't rum pump through self test connector. Going to try bypassing FPR, then check fuse link. I'll get right back to ya'll.

Well, turns out it was the fuel pump relay after all. $10 part - 10 second fix. The other one wasn't that old so I just KNEW it couldn't be that. Just goes to show you, Keep It Simple Stupid. Thanks to you guys, I now know more about this van than I really wanted to. 
If I have a similar problem, I now have all of the tools, techniques, and info to fix it in minutes instead of days. I'll check back on this site frequently in hopes I can share some of the love y'all have shown me.
Thanks ever so much,
Chuck
