"I do not hear the 1 second primimg sound that I think should occur when I turn the Key to position II."
• This is normal. The LH 2.2 doesn't run the pumps till an "Ignition OK" signal is detected during cranking.

"My other question is does this jump at between 4 and 6 power both pumps?"
• Yes. The input to fuse 4 (left side) is where the Fuel relay voltage is applied. At that point, voltage goes thru fuse 4 to the tank pump — and also directly to the Main pump.

If you remove fuse 4, and apply voltage to the hot (left) contact, only the Main pump will run. Conversely, voltage to the right side contact (fuse 4 removed) will run just the tank pump. Insert your meter between 6 and 4 left (fuse 4 removed) to read Main pump amps.

Despite what the fuse label says, Fuse 6 has nothing to do with any pump on US cars. It is for the K-jetronic FI system still used in other markets. In the applications above, fuse 6 is just a convenient voltage source. The hot (left) side of any fuse 6 thru 10 would work as well. (These five fuses are always hot with Key off - or Key in your pocket.)

a piece of half-inch cpvc pipe a foot or two long fits in the filler intake hole. you can put your ear up to the end of it and hear the pump clearly.
a similiar size in copper or a piece of cheap garden hose would also work.

My mechanic put the end of a large screwdriver against the fuel tank and the other end on his ear while the car was idling. If you can hear/feel the vibration of the in-tank pump, then it is working.

I don't think you have anything to worry about. The current draw for the in-tank pump sounds right, and it's usually pretty hard to hear unless you use a jumper to run it without anything else going. Usually the only way you can hear it is to put your ear to the filler while the car is running, and even then it's pretty quiet.

Not sure why you're not getting current draw on the main pump, are you doing that with the car running?

Whether or not the pump will "prime" in the II position seems a bit random -- if the car runs well, don't sweat it!
