1994 Buick Century 3.1
Fuel pump relay is not powering the fuel pump. I was able at one point to jump the orange wire to the gray wire but it will not even do that now. I know the fuel pump works because I can jump from the battery to the gray wire and it will turn on.
I used a multimeter and tested the volts from the orange wire on the relay to the neg post on the battery and it is only reading about 1.3 volts. Is this normal?
Checked the fuel pump 15a fuse and it is ok.
I am getting spark. Could it be the crank sensor? How can I test that? (It is above the start I believe)
Could it be the ignition control module? How to test? Location?
What else can I test with the multimeter and post back with the results to help further diagnose?
