I recently purchased an 87 Jimmy W/ A TBI 305. It was not running when I bought it due to no power to the bat+ terminals or the ecm b fuse on the fuse block. There is absolutely no power to any of the orange wires that go to the fuel pump relay, oil pressure switch, and ecm b fuse. So far I've replaced the fuel pump,fuel filter,oil pressure sensor, coolant temp sensor and ecm. Still no power?? Anyone have some answers for me?
