Hello 914 World... What a terrific site and help to anything 914. Now here is my dilemma... Need help in Denver, CO
I have been sorting my friends 1973 1.7L FI D-Jet 914 for a couple months now including all fuel and vacuum hoses, hell hole, clean and lube distributor, new points and condenser, fuel injector seals, intake rubbers, all Rennlist checks... et al.
Good news.... She runs great when I start her with a remote starter...
Bad news is the motor starts really hard and won.t stay running if I use the ignition switch or even attempt to push the yellow wire onto the solenoid when it is idling after a remote switch start. Of course it makes sense that maybe the ignition switch is crap and bleeding off current or...? I have ordered a new switch but... Maybe I missing something here....
Like I said it runs and is so tuneable if I remote start and dead to me if I use the ignition switch as designed.

Anyone got any ideas on how to check this out...

BTW, I have wrenching on bikes Triumph, BSA and most of the Japanese stuff nad a few VW bugs since the 60's and find the 914 pretty wrench friendly...

And I should have added that the white wire that goes to the red wire on the AAR is switched 12 VDC. Hot at all times the key is on. Comes from pin 12 on the relay board to the AAR. Wire is in the engine harness.

Thanks to everyone who chimed in... dang weather is so bad I can't get at it for a couple days... BUT I will and I will do the checks recommended and post results....
Thanks jcd914 As you said, no white wire on coil w/ 1.7 D-Jet...
I spent quite a while tonight researching any post about a white wire on coil and came up with the L-Jet 1.8 using that white coil wire to trigger FI pulses (914club forum)... No reference to a 1973 D-Jet 1.7L... so off it comes to remain disconnected...
BTW: When that white lead is connected to the + power side of the coil the fuel pump runs constantly, hope that tells someone something.
Sure hope it still runs with the white wire off the - coil terminal...
I'll let you all know.........

Thank You rick 918-S for the color wiring diagrams.. BIG help
Thank You cwpeden, I will get to the relay board soon
Thank You Tom, I will also check that yellow wire for voltage and the spade connector for voltage with key on...
Majkos When I say remote start I am talking a handheld switch with wires running to the solenoid. No relay setup. The growl I am referencing is the Hum of the fuel pump running constant. >And that dusting of snow we got here is approaching six inches as well..LOL
Thanks SLITS, the starter circuit info is really helpful. BTW, white wire to AAR is present and hooked up. The white wire I'm referencing is off the FI harness near the coil. Doesn't show in any 1.7L wiring diagram.. weird deal...
Below I have posted a wider perspective photo of that white wire...
Stay tuned Gentlemen.... more detail to follow asap... Best, Broz97

Slits is right about pin 12 as the power source for the white wire to the AAR but the diagrams I have show pin 12 is down stream of the fuel pump relay and should only get power when the relay to energised and the pump should run.
If the white wire you have hooked to the coil, should be hooked to the AAR then this would explain why the pump runs anytime the key is on as you are back feeding the fuel pump from the coil.
That would also mean that the white wire you have hooked to the AAR is for the cold start thermo switch or the air temp sensor. If it is the cold start wire then your cold start injector will ground thru the AAR and spray all the time the engine is cranking. You are probably going to have to use an ohm meter and pull the ECU connector to trace out which white wire goes to which terminal at the ECU and the fuse panel.
Not sure how any of that ties into the starter circuit.

Back to work here after a cold snap....

A couple things Jim... The AAR wire has an end specific to its plastic block connector and the AAR is working. The cold start injector wire is a multiple wire specific plug and it is inserted. Maybe another look at the harnesses and the mystery wite wire in situ will help.. See Pics.
Can anyone with a 1973 1.7 take a look at their harness and see if they have a white wire located in the same place. The harness in question has a gray sheath on my car and the wire comes out near the coil of the bundle that has the FI / distibutor plug lead and the 3 wire plug lead to the cold start injector. The mystery wire is some distance from the plenum grounds as you can see.
