Suggestions:
1. Charge your battery 11.67v is a bit feeble.
Measure actual battery voltage at the batt terminals- is there a voltage drop at the FP relay?
Just thinking you may have poor connections between the battery and FP relay so that you get way less than 11.67v under load. Easy to eliminate as a potential source of problems.
2.If the relay did not click when you jumpered it:
1. relay is defective,or
2. connected wrong terminals
3. Remove relay and test. New relay is $10 :K.A.E. 2.408.120 ? 99661510100 For $10 at this stage why not just fit a new one?

4. If you know what you are doing, connect FP direct to battery with a fused jumper cable.Polarity !
