    EFI wiring help on 86 5.0 (pin 30 & 46)

    Well, after doing more point to point & resistance checking on my wiring and voltage comparisons and even tried the test light procedure to see if my computer failed and it was. Well, not entirely not the circuit for the fuel pump. I had a local Mustang guy tell me just pull your EEC and try my...

    EFI wiring help on 86 5.0 (pin 30 & 46)

    Well I jump the pin 22 to ground and the pump runs. I also checked the wiring (pin 22) from my relay coil back to the EEC/60 pin connector and it tested out OK with my digital multi meter. Also all the grounds tested fine as well like pins 40, 60, and 20. So my EEC should be well grounded...

    EFI wiring help on 86 5.0 (pin 30 & 46)

    I'm not sure if it matters but I have a 86' "Speed Density" 5.0 not a Mass Air with a VJ1 EEC. So does effect the notion of hooking pin 46 up to the "start" like for a A9L? When looking at the Veryuseful's EEC diagram of the 86' Mustang it does not show pin 46 going anywhere to pin 30. Is the...
