Jumper from pin 30 to 87 of that relay -- pump should run continuously regardless of key position. If it doesn't, check voltage at pump -- should see 12v on one terminal and ground on the other.
> Checked pin 14 - 13 12v only when cranking starter Sounds like bad 15 contact on ignition switch. When you turn the key to crank the 15 contact moves to another area of the switch, so it might well be making contact there and not in the regular position.

If not then you have an open circuit coming from the coil or the ign switch, or bad ign switch. If you don't have 12v here then nothing will work. > Question: The coil shows this input coming from the #15 voltage >source (gray area at top of page) > This is ignition switch output, right? Yes, should be 12v with key on.

That wire supplies the crankcase vent heater -- little heater in the tube btw the oil tower and the intake boot. It's the heater that's grounded at current track 15. The number is a coincidence.
