I have an 86 fiero, 4 cyl. It does not seem to have power to the injector. I have done most checks, fuel pump-ok, pump relay-ok, injector-ok, fuses all good. I put fuel in the TBI and it fires right away. I'm thinking electrical but not sure where exactly I should start, please help if you have any pointers. Thankz
