Ok, got oil filter on, plug in, oil filled. Now to get the pumps running....got 12v to ground on 30 at fuel pump relay (may be 87) and voltage across 30-87 which tells me i have potential..which tells me open circuit, as it should be. I jumper 30 to 87, and nothing happens. I check my pumps, and got no power....so I start tracing.... Now I may be answering my own question here, but.... I have previously cleaned ALL my ground points, EXCEPT.... the one behind the passenger side tail light.... I pulled the panel back a little, and looked with a light, can barely see it, but it looks very "tarnished". Could this be my problem? If the answer is yes, should I still not have had 12v on the positive wire at my pumps when measured to ground?

Input, thoughts, suggestions? I already will tackle the obvious and clean that ground tomorrow.

Thanks!
