Thanks Jim. I've been messing with this thing for WEEKS now, off and on. Jumping 9 and 5 causes a solenoid just upstream of the fuel pump to click, and that's it. Pump does nothing.

I've tried everything I can think of and read all I could, but it's
just beyond me. Sad

Robin,

You are obviously literate and have an IQ well over 80 - Therefore, you are very probably more capable than anybody you will be paying to work on this. (One of my standard lines..)

Now, you may just have done your diagnosis in the line above.
The fuel system has three(3) parts.. the fuel pump (big cylindrical thing with fittings in sides above and below and electrical connection. The solenoid valve is much smaller and typically between the pump and the carburetor. It has its fittings in the ends.

The solenoid valve should click once and once only when you put the jumper in place.
The pump will click continuously - if it is working.
You may not even hear the solenoid. It is not very pronounced. But the pump is easy to hear.

If the pump is not cycling, it could easily be the internal contacts. They are easy to clean and I am sure someone has written this job up for the GMC people somewhere.

If it is cycling, loosen the fitting at the carburetor (real PITA to get at) and see if fuel is leaking out with the jumper on.
- If Not, your problem is in the fuel system nearby.
- If It is, the problem is now the ignition or the carburetor.

Test the ignition.
Pull one spark plug cap, put a screw driver into the cap and arrange it so it is near metal like 1/8" or so. Put the jumper back on and hit the start button.
Did you see a spark?
- If not, clean the points and try again.
- If yes, the problem is in the carburetor.

That may just need cleaning.

Let us know before you spend money.

If given minimum care, these things are anvil reliable and so easy to take good care of that it is awesome (in the true sense).
