Not getting power from key to starter, can jump power and start engine but not from key Options

[Type 47]

We've been trying to figure this out for a couple of days. The car was converted to carbs by the PO and was running and starting fine before I took it apart.

Now, nothing happens when key is in start position but we can start if we touch pole 2 (powering fuel pump) and 4 together from open FI harness plug receptacle.

pole 1 being drivers front, 2 passenger front, 3 drivers rear, 4 passenger rear.

one other difference is that now using a Carter fuel pump versus the Faucet that was originally on the car.

Here is the relay board schematic



When key is in start position you should have 12v coming into the board on the top pin 1

And it then goes out to pin 6 to the starter. Via trace on the board.

Both are the fat yellow wire

If I understand the 4 terminal FI plug as you’ve labeled them - you are basically jumping 12v from the power supply relay to the starter motor pin 6

Eventually if you keep doing this you may damage the relay board. The trace from the relay to what your calling pin 2 isn’t sized to support the current your probably drawing through it.

You need to figure out why you don’t have 12v coming into the board from the cabin / ignition switch on the big yellow wire on pin 1

Probably a faulty ignition switch or possibly you have disturbed or haven’t properly bypassed the seat belt interlock relay below the passenger seat.

Not sure why your relay board has a 1980 date stamp on it? Possibly rebuilt by someone?

OK, I bought the car a little over 10 years ago, everything running, then I disassembled it and sent it to be media blasted and painted. the car basically sat on my lift for 10 years and then 20 weeks ago we got dedicated to putting it back together. I was not happy when I saw the date on the board either.

I have a feeling it's something with the seat belt interlock relay. I was blown away when one day I came out and my son had it all plugged in. It makes the buzzers buzz but damn there are like 30 wires going into it.

my son has also been all over those yellow wires.

I'm sure when he reads this it will help.
