With the car running when cooling fan kicks on, but not every time, but on occasion the car will idle rough. Checked fuel pressure about 40 lbs. While checking the fuel pressure I took the fuel pump fuse out then put back in and the cooling fan kicks over when inserting fuse. So my question is why would the orange wire that comes off fuel pump fuse that goes to oil pressure sender and to ecm? Would it affect the green wire that comes from ecm to the cooling fan relay? That is hot until the ecm is told to shut off power to the fan relay to turn on fan. Correct me if I am wrong. Thanks.
