New-to-Me 74 1.8l_Where to start on electrical issues Options

[rcautox]

Hi all,

I've been scouring 914 world for help on getting a new-to-me '74 1.8l running. I've reviewed Auto Atlanta's informative video on the 914 fuse & wiring and I think I follow the gist but may have missed things. I've also studied the simplified diagrams on Pelican Parts which have been helpful to understand the 914 layout.

What I've done:
1. new battery
2. new ground strap straight to the transmission bolt in the rear of the engine bay
3. cleaned battery connections
4. cleaned the fuse panel

When I turn the key the only thing I can see working is the marker lights and the clock. So no fuel pump, no start, etc.

Can you all point me to a few areas to tackle first to determine the culprit(s)?

Thank you for the detailed suggestions. I gently pushed the AFM flap but no fuel pump. I moved to the yellow wire, no power or continuity. I figured I need to focus my efforts on the ignition switch and I found the relay was unplugged. I now have power to the gauges and the fuel pump kicks on when I push in the flapper.

If I’m reading the wiring diagrams correctly the yellow wire goes from my ignition switch to the starter. So next step I should think is the lack of continuity or power when the ignition is on? The starter does turn over if I jump the terminals.

The previous owner left a bunch of parts including a steering column so, along with the oddly unplugged ignition switch, I’m guessing they had identified this as a possible issue. Any advice on how to identify the source of the issue with the yellow wire?

Good find on the relay. So, does it still not crank with the key?
