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)?

Regarding seat belt bypass-I pull the passenger seat, it looks like the bypass has already been addressed? Photo attached

Unfortunately it is FI, have to love 70s FI electrical gremlins….

I bought it and a 72 from the previous home owner. She lives next door so easy enough to ping her for info. The 74 ran fine until it just died one day. Her ex thought it was electrical. I’m starting with the simple stuff like battery and grounds.

From reading this site I suspect I need to move to the ignition next. I had a VW Vanagon with a 2.0 that also provided unreliable electrical services. I could bridge the starter with a screw driver with the key in the on position. Considered trying this on the 914 but I’m thinking fuel pump not running needs to be addressed?

Appreciate the help

on a stock 1.8 L Jet the fuel pump only runs when cranking.
then the AFM unit takes over running the pump once engine fires.
does not run with just the ignition on.

you can test by taking the air cleaner out and unclipping bottom.
leave the AFM plugged in.
with the bottom off you should be able to see in to where the AFM flap is.
with ignition on push the AFM flap carefully in.
you should hear the fuel pump run if its all ok.

ah i see @Van B has already instructed.

i'd check all the ground points are clean and corrosion free.

wiring diagrams can be found here.
