'85 245 T Not getting fuel

My son and I got our old '85 245 turbo running after sitting for a few years.
The idle was great. It did spit and sputter a few times on acceleration but did
run.
then at idle it quit. after restart it idled fine for a few minutes and then
quit. Now it won't restart.
It's not getting fuel. The relay seems to be fine. The pumps were replaced not
too
long ago... However, when I turn the key on I don't hear the low hum of working
pumps.
I have a hard time believing both pumps are bad. If the check valve or filter
are clogged would that keep the pumps from running? maybe from back pressure?
Are there any other electrical connection that tends to fail?
Any thoughts or help before I crawl under the old girl would be greatly
appreciated.

TIA
 
Check the fuse box on the pillar, On my 93 245 I used a dremel tool to clean
all the connections, use a bit of dielectric grease and change all fuses to
ones with copper contacts, all the gremlins went away. Another source of
problems was the fuel pump relay, it is located on the passenger's side if
you pry it open you would see some cold solder joints, re-solder them, or
change the relay and you should be all set.

Disconnect the fuel line at the filter and turn on the key, fuel should spew
out at a good rate.

If the pumps are not turning on, the first thing to do is check the fuses
for oxidation, then check to see if the relay is closing. If it doesn't
detect pulses from the ignition system then it won't engage.

These old K-jet systems are notorious for clogging up with contamination if
they sit for a long time. If the pump is running but the engine won't start,
it's possible the fuel distributor and/or injectors are clogged, it's a real
mess when that happens.

On a K-Jet car (which includes all 240 Turbos), the relay is located on the
driver's (left) side, the LH-Jet 240s have it on the right side. All other
advice applies.

Thanks!

This is what we have done so far.
Replaced all the fuses with shiny new ones
and cleaned the contacts.
Checked the relay. I feel a click when the ignition is turned on.
Loosened the fuel line at the distributor and found no flow.

That's good info about the distributor I'll keep an eye on it.

It looks like I'm going to have to finally get under the car (no easy feat
since it's parked on a city street) and start chasing the line back to the pump

You can access the main pump wiring under the back seat and check for power
there without getting under the car. Also it's entirely possible for the
relay to click and yet still be bad. Open it up and look at the solder
joints, the cover popps off pretty easily using a small flat screwdriver or
knife blade.

Well, what a surprise! The main fuel pump is not working.
Okay, so that has to be replaced. Which by the way seems
to be a some what unusual pump since its for an '85 turbo.
ipd has them on back order.

Another thing came up. As we poured 5 gal. of gas in the tank
about a pint dripped on to the ground. Obviously there is a leak
on the filler tube.

Question, does the tank have to be dropped to replace the filler tube?
Am I on the right track?
 
also check the condition of the two connectors at the secondary feul
pump (the pump beneath the vehicle) .This pump is out in the open and
crudation (coined by me) can occur at the connectors. Pressure valve
shouldn't stop the pumps cold.
