ive got an 87 iroc 305 tpi the guy i got it off said it ran fine till i just died one day so i started to trouble shoot it its getin fire and will sputer if i spray a little gas down the intake i couldnt hear the fuel pump coming on so i checked the fuses and relay they seemed good so i ordered a pump i decided to put an acess panel in the trunk so i get the pump put it on and nothin i dont have a volt tester but i can tell its not geting full power cause the test liegth isnt as briegth as it should b also the purple wire is the only one with power y does it go to the gaudge only and not the pump the pump positive is grey but when i test the incoming grey its dead ive been trying to get some wiring diagrams to help me out cause the harness has been cut a few times so maybe its shorting out somwhere
