TBI for dummies

[Nazzcu]

I need some assistance troubleshooting my TBI setup. The truck is 87 silverado originally came with 305. Prior to my purchase the engine was swapped with a 92 350. The engine runs good just a little rich, when the ignition is turned the fuel pump runs nonstop and does not cycle back off. The fuel gauge sits at the 3:00 position while running and It is missing the oil switch beside the distributer.

I need some help getting this TBI back to stock condition, most of everything is missing or unhooked, and I don’t know enough about it do simply buy the parts and reconnect. In addition there has been some shadetree wiring done.



Can someone ID all these for me.



The brown wire above runs back trough the cab to the fuse box and is tied into the ECM fuse.

Thanks for any help. If someone can breakdown each part of this system for me I can get it working again.
