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? |
