Fuel Wiring Diagram 1990 Ford Ecnoline 150

Let me start out by saying that I am NOT a mechanic. (One of these reasons I am here on this forum.) So if you have suggestions and leave a reply, please keep this in mind.
1989 Ford E150 Clubwagon. Been sitting a few months. Even when I DID drive it, it would sit for months in between use. Always seemed to fire right up though. (Sometimes needing the battery charged.)
I bought a new battery for it a few months back, as the old one no longer held a charge. (10 years old?)
Tried starting the van today...it turns and turns and won't start. Although it has plenty of fuel in it, BOTH FUEL GAUGES READ EMPTY. I went ahead and put a few gallons of gas in each tank. Tried starting again...turns and turns, won't start. I took off the air filter and sprayed some starting fluid inside...van fired up and ran STRONG for a few seconds, then died. Tried this a few times throughout the day, same results.
After doing some research on the internet, I found one suggestion that said to listen for the fuel pump to engage when turning the key. I didn't hear the fuel pump engaging. More research, I found a tip on resetting the fuel pump relay with a switch. (Located on the passenger side, under the dash. Orange and pink wires.) I reset the button, listened for the fuel pump to engage (this time it did,) and the van fired up for a few seconds then died. Tried more starting fluid, same results.
I read somewhere that when it fires up with starting fluid, that this confirms you are getting spark. (Correct?)
I'm curious why the fuel gauges on BOTH tanks read empty when I KNOW there is plenty of fuel in the tanks. I read that the gauges are operated by 'sending units' in the tanks. Could whatever is powering these units be connected to lack of fuel delivery?
Appreciate any tips anyone might have.

Thanks for the links Poppy. I'll check them out. In the meantime, does anyone know why the BOTH fuel gauges would fail at the same time? This in adddition to no start/no fuel? There has to be a connection.

Poppy, I'm looking at the wiring diagram you link posted. Does this apply to my 1989 E150? I'm not real experienced at reading wiring diagrams. Are the sending units that run the gauges part of the pumps? Being that BOTH fuel gauges are reading empty, could it be whatever powers the pumps also powers the sending units? I KNOW there is plenty of fuel in the tanks therefore I know the gauges/sending units are not working. No power to pumps/sending units?

If you look at this wiring diagram that included your tank switch, there are two things that everything has in common.
Power by way of the Blue fuseable link to the fuel pump relay, then through the relay to the fuel pump inertia safety cut off switch (mounted high on the driver's side firewall, by your left foot) then power through the selector switch, onto the pumps (and yes the gas gauge sending unit is inside the tank).
Ground G201. IF that fails, it all fails.
I believe that G201 is located at the bottom lip of the dashboard by the driver's left knee.
OR it might be behind the left kick panel, near the driver's left foot.

YES, the E150, F150, 250, and 350 and Bronco should all be the same. (Diesels would ofcourse have some differences.)
Make sure the RED button of the fuel inertia switch is DEPRESSED.

Thank you for your reply.
I have already checked that the inertia switch is depressed (as previously stated.) I'm assuming that based on the fuel gauges reading empty (even with fuel in the tank) that there is no power to the fuel selector switch. In turn, no power being supplied to the fuel pumps.
Again, being that I am not a mechanic, let me ask probably an obvious question... Should I check for power from the switch, working my backwards to the inertia switch? (and on down the line from there?) Any simple way to do this for a simple minded guy? I've read that many people use a tool that lights up that shows power.
Thank you again for your help.

What does 'Ground G201' mean? Make sure that the wire is grounded to the body somewhere?
What does it look like?

I would use a test light. I picked up a few of them one time at a local dollar store.
A likely culprit is the fuel pump relay. It is probably the one with a GREEN top. If you pull the relay, two of the four pins should have power. Then if you jumper the two big pins, the pump should come on. If it does then you have a bad relay, change it and you might be done.

**UPDATE**
I haven't had free time to work on my van up until today. I tried starting it just for the heck of it. When I got the key turned to the 'II' position, I saw the gas gauge climb all the way up to full. (Both fuel gauges had been 'dead on empty' prior to today.) It started for a minute then died. Tried starting it again, turned and turned, no fire.
I noticed that when trying to start it, the fuel gauge would drop from full to empty. I noticed that when I turned the key to the 'II' position and gently wiggled the key right or left, that the gauge would rise or drop. Could it be that something in my key (tumbler?) is loose, and therefore cutting power to the fuel circuit? If so, does anyone here have any suggestions on tightening the key tumbler or replacing it? Pictures would be extremely helpful if you have them.
Again, every time I try to start it, it just turns and turns, no fire. The only difference I've noticed is that the fuel gauge level is affected by slightly 'tweaking' the key in the ignition.

meant to say 'no fuel' (Not 'no fire')... it 'fires up' fine with starting fluid and then dies...so it has plenty of fire.

Wow! Thanks for the info Poppy and the quick reply.
I checked your links. Forgive my being a rookie, but I didn't see anything in there related to power from the ignition switch to the fuel circuit. Maybe it was there but went right over my head. Do you know if there is a photo available of whatever part(s) is/are involved from turning the key in the ignition, to sending power to the fuel circuit? Or maybe just some names of the parts I could research on my own?
thanks again for all of your help!

My first response to you should have explained the electrical supply to the pump. Where did you get lost?
I posted info on the ignition switch, because wiggling the key should NOT affect the gas gauges. Possible weak connection within the switch.
Are your tanks full? Otherwise, IIRC if the gauges get shorted to ground, they would show FULL.
