I used a test light and no current is going to my 2 two wire square conectors. On my 2 bullet shape fuel injectors. 4.3l v-6 engine. All fuses are good, installed a new electonic control module in distributor and fuel pump in tank runs good. Disconected fuel line plenty gas going to carb. Vehicle runs when gas is poured in manually. But can't get injectors to work. Please tell me what am I missing. Vehicle had been fine drove it up to my garage cut it off, afterwards wouldn't start anymore.

The voltage wires at the fuel injectors are red and white, probably goes hot with the key on. Any voltage on those wires? If not, have to go back to injector fuse. Even if the fuse is good, you still need to check voltage at fuse circuit, key on. Let us know what you find.

Thanks very much I tested before with key on and while rotating engine. I will try again and check the injector fuse and voltage at the fuse circuit. With key on. Today is first time finding your reply answer to my question.
