got code 54, its a 85tpi. the pump doesnt come on anymore, used to just come on when engine is cranking after a while, but not anymore. oil pressure switch is good,
the ign wire is good to the computer, pump is good, relay is good, also the green with a white stripe wire from ecm to relay is good,(tells relay to switch) cant get the pump to turn on through the aldl, if i give 12 volts to the relay it comes on. the only cut in the wiring harness, is where th ecm fuse is. there is a orange wire and a black wire coming from the ecm fuse holder, the black then gets spliced into an orange and straight to battery +. any suggestions? how is the ecm fuse supposed to be wired out? hard to troubleshoot the 85, everyone has schematics for 86 and up. dave

 

Here are a set of '85 wiring diagrams on line:
