Just venting right now. Went to replace the upper steering wheel bearing and found that approximately half the wires that are situated there were cut and just hanging. The clock spring looked like it had exploded. Murphy's Law...the 2nd issue is no fuel to the rail. Swapped relays and it fired up so I headed to town for a new relay. Put the new relay in and no problem. Next day...no fuel to the rail. Swapped relays again but still no fuel. No signs the pressure regulator faulty so I'm assuming it's the fuel pump. Any other possibilities?

Most likely a fuel pump, but could be a bad ground, or even safety shut off switch. Really need to jumper the relay, crawl under there back by the tank with a test light to know for sure.
Relay is fine which leads me to assume the pump is not ok. Guess it's time to drop the tank. Thanks for the input, Tiha.

Check your other critical relay, the EEC Power Relay. If it does not power up, neither can the fuel pump relay.
Hint: If your "Check Engine" light does not illuminate Key On, Engine Off, it might be your EEC Power Relay.

Thank ya, Motech. Will be the first thing I look at today.
Yo ryeder,

When the ignition is switched to the ON position, it turns the EEC Power Relay on. The EEC Power Relay provides power to the EEC-V processor and the control side of the fuel pump relay. Power for the fuel pump is supplied through a fusible link to the starter solenoid (battery side). From the fusible link, current flow is through the fuel pump relay and Inertia Fuel Shutoff (IFS) switch to the fuel pump. The IFS switch is a safety device used to shut off the fuel pump in the event of a collision. If the IFS switch is "tripped," it must be reset by depressing the white or red button on the top of the switch. The fuel pump relay is controlled by the Powertrain Control Module (PCM).
When the ignition switch is turned to the ON position, the fuel pump will operate. If the ignition switch is not turned to the START position, the PCM will shut the fuel pump off after approximately one second. The PCM will operate the fuel pump when the ignition is in the START position to provide fuel while cranking.
After the engine starts, the PCM will continue to operate the fuel pump unless the engine stops, engine speed drops below 120 rpm, or the IFS switch is "tripped."
If Horn HONKS, swap Horn relay into FP RELAY SOCKET

- Shake, wiggle, bend the B(+) circuit to the fuel pump relay.
- Lightly tap the fuel pump relay to simulate road shock.
- Shake, wiggle, bend the Power-to-Pump circuit between the fuel pump relay and the FPM splice.
- Key off.
- Inspect the fuel pump relay connector for corrosion, damaged pins, etc.
It was the pump. Changed it out and it fired up. Thanks for all the info...
I agree. Diagnosing problems is probably my weakest point. Guess I should of been trained in mechanical work along with auto body. Back then, greasy engines couldn't come close to restoring a vehicle and shooting on color. Of course back then, it was no or very few pre-made body panels and lacquer paint. Real old school. Lots have changed since then.
Good information...thanks
Yo ryeder,
Looks as New!
Good work!

Definitely not up to Mecum standards, but I'm almost satisfied...and thanks. The photo does look good...lol

dont forget a local 'shake down cruze' if going ona long trip and just gettin a 'car' together. I regularly do an hr trip 1st (no more simple dailies for a wk or 2) on anything I'm rest0modin, sellin or otherwise.
The trip? from where to ME (& that's our biggest state "up heyah")?
