Firstly I tested the pumps that came out of the car we are trying to get running again, which both happen to run with power applied. 1st got 1.1 and the other got 1.2.

Then i tested 2 of these spares that had been sitting with old fuel. One DID turn on with power applied and went from 1.3 to 5 and as the numbers increased the pump slowly shut off at 5. I disconnected and applied power to the second spare. I got no function, so I did a current draw test on that one and got 6.98. I could feel it vibrate but no function.

What does this mean? I don't know since i don't have specs for the pumps...but through testing these 4 pumps...it appears that a higher number is no good and the pumps that came out of the car are in fact good????

I used the multimeter setting 10a and tested the pumps directly to the terminals on the pumps themselves since they are all out of the cars on the bench.

Anyone know what numbers these pumps should be giving if they are good?
