Hi guys, i am in the middle of building a carburated 383 for my 89 Firebird Formula. I removed the ecm and the un needed wiring. then i realized i accidentally cut some of the wires for my fuel pump. What do i need to do to get the fuel pump to run without the computer. I read that the Green/white wire needs to be hooked to an ign power source, the black/white goes to ground, the tan/white goes to the other tan/white wire. But where does the orange wire go to?

 

Also, if i removed my computer do i need to do anything with the vss/bufferbox to get it to work right?

 

That is why you don't cut anything ; you just hide the old harness out of the way in case it is re-needed


To the battery

 

i had to replace my fuel pump today so i made i trap drop above the tank. i have the fuel assembly out and everything and i replaced the fuel pump. so i connected it to the wiring harness just to make sure thier were no electrical problems, but there is an electrical problem cause the fuel pump doesnt make any noise, to make sure the fuel pump was connected right i connected the wiring from the fuel pump to a battery just sitting in my garage and the fuel pump works by doing that. could it have somthing to do with have a bad carbuerator?

 

sorry i forgot to mention, its an 84 camaro

 

Obviously you have no power to the pump
checked the fuse?

 

the fuse was fine, the relay wiring maybe?
