No power at the + coil while cranking indicates that the engine controller is not seeing a crank signal from the HEP so it will not actuate the ASD Relay or there is an issue in the ASD circuit.

Before we get into that lets be sure the ASD circuit is OK.
1)When you initially turn the key on do you hear the fuel pump cycle on for 1 second?
a)If no, connect your test lamp to a known good ground and the + coil terminal.
Turn the key on, did the test lamp illuminate for 1 second and then go out?
b)If no, we will diagnose the ASD Relay circuit.

When we are done we will know for sure if the issue is with the engine controller or lies somewhere else.

I have no fuel pump action at all.
I will check on the light.

I have the light.
I'm putting in the distributor pick up next. Getting it tomorrow.

I'm tempted to rebuild the power modules myself if major internal components like the ASD relay and 10 pin connectors are available.

He is working on a 94 Shadow with a SBEC and external ASD and Fuel Pump Relay.

94 Shadow, tbi, automatic, 2.5
New: fuel pump, computer, relays, H.E.P., no fuel pump still.
All fuses checked.
Ideas?
Also, anyone have a fuse box diagram of what fuse for what?
Can't read my fuse box.

I've got spark back, yay!
Still no fuel pump.
I jumped the relay socket so it was hot, but still no fuel.
I'm curious, what does the fuel pump harness go through at that point?
Fuse box?
It isn't a ground issue, there is no power at all to the pump. I even tried piercing the wire above the pump plug.

Thank you. It looks like a straight shot to the pump from the relay. I'll run a new wire.

Nah,
Looking at the fuse box diagram, I have a few questions.
I see on the bottom row, the two outer most fuses, they seem to protect the same things. Can you clarify?
Also, what is the lower right most fuses amps?
Also, what fuse was for the aircon I no longer have?
Lastly, as I have no pwr seats, no cruise, no pwr locks, can I leave those empty?
I really appreciate all your time and help.
Half the fun in owning a car, for me at least, is in the planning of modifications.
It currently has Neon snowflake rims, and slightly talker tires in the rear.
It is an R/S model, though I think that means it's a base model in reality.

Fuse #4 (Bottom Left) 5 Amp - Supplies Power To Warning Lamps and Tach Drive Module
Fuse #1 (Bottom Right) 4 Amp - Supplies Power To Illumination Lamps

A/C - Fuse #6 10 Amp - Also supplies power to the Airbag Module, Rear Defog Switch, Overhead Console and Back Up Lamp Switch

You can leave the fuse out for the Power Seats (Circuit Breaker #11), Power Door Locks (Fuse #2) and Cruise Control (Fuse #3) since they do not power anything else.

She's finally done.
Major issue turned out to be a hack job of some wire splicing I only found when I went to connect the new fuel pump wires I ran.
I do believe it is running better than before though.
The new ecm likely is why, but I also gapped the plugs at .40
All the champion plugs looked good, except number 2 had a little dark, dry oil residue. Makes sense, as it uses a very little oil. New valve seals may be in order.
Now to figure out why the pesky engine light is off and on.
I'm guessing tbi related, as it hasn't been serviced at 150k-ish.
