Are you getting both power & ground to the fuel pump? THIS POST should help you with identification of the appropriate wires.
What brand of pump are you installing?

I agree with the "you do it your way and i will do it mine." Like I said, I know how my luck goes. In my line of work we cant afford an "oops! I should have used the other meter!" mistake. I just take that attitude home with me.
I love the old school test equipment like Swartlkk has. I still have a vacuum tube O-scope I use occasionally. Heck, I work at the FAA. We have some equipment that still says "Property of CAA" Google THAT and you will appreciate how old it is!
Have a good one everybody!

As I was going to do the ground test, had my wife to the key to check for power at the pump again also.... battery is totally dead...... charged it and it is not keeping a charge at all..... so off to the store to get another one.....
If it is not one thing it is another
