Okay then, it's probably fine.

If you can still hear the pump motor run for ~1 second after you turn the key
ON, you probably have the typical problem with the pump check valve.
There's a little rubber bit in there that disintegrates after all this time. I
replace that bit with Teflon when I rebuild the pump head.
If the motor doesn't spin for that ~1 second, check to make sure you didn't
disturb wire #19 just to the left of the IAD, against the "firewall."
