1975 is a d-jetronic
1980 is a k-jetronic

D-jetronic fuel pumps are supposed to make only about 30 psi while k-jet run about 8 psi. Don’t quote me on this.

It’s rare that a car sitting that long will pump clean fuel for long. Usually the swirl pot filler line or return line that also fills the swirl pot will be clogged. You really shouldn’t try to run the car on its own fuel tank and lines if you have not cleaned them yet.

I suggest you get a fuel pump setup from a k-jet.

I have fried the solenoid wire on a car by cranking it too much. Make sure the wire is t burnt up. Beyond that, it’s going to be some good old fashioned Dick Tracy work on figuring out why the solenoid isn’t getting power when you turn the key.

I think you’ve got a project ahead of yourself, but it sounds like you know what you are doing with cars in general and will be fine in the long run.
