So I think the b+ in my diagnostic port doesn't work... Ive tried jumpering them to start my fuel pump to set the pressure with the fpr with no success.
And I now tried to plug in my a toyobd1 diagnostic box and it's not working either, the common denominator is the b+ port.... How do I test it/ fix it? Either that or I have an obd1 diagnostic tool for sale!
Thanks Dylan.

B+ is battery positive get a multimeter and check it for 12v

If you have an immobiliser, make sure it's disarmed, caught me out before (it cut power to B+).

Also turn the diagnostic port over and measure it from the bottom to check it's not just corroded on top. For your dongle and running pump just run a wire from the thick white ones in fuse box
