im having an issue but im not sure what the cause is. hooked up my harness for a 90 5.0 in a 69 cougar efi conversion. i have power to the harness i check the coil tfi and a few other places. but when i go to crank the motor over the solnoid just buzzs. i know the battery is weak but i jumped it and let it stay on for 10 mins but still the same thing. any ideas what would cause this issue....also on a side note the 5.0 ho manifold is reversable which i had to do. anything else i should do besides routing the efi harness on the other side? i was worried the injectors would get the right pulse to the right signal per firing order since i reversed it.
