Ok John, next thing I would to is:
Remove the 1" cap in the center of the IP ( #2)
Remove the 5/8" 12 point delivery valve holder #15 under the 1" cap. the sealing gasket #16 will stay on the holder.( careful not to drop the spring #3 under the holder )
use needle nose pliers to remove the delivery valve assembly ( looks like a 3/16" needle and seat about 1/2" diameter.) #4
Now if you look in the center of the opening you should be looking at a hole with a 5/16" plunger #10 recessed about 3/8" deep. ( should be a small hole in center of the plunger )
Turn on fuel pumps for 1-2 seconds and verify fuel shoots out of center of IP ( have a rag or container there to catch the stream )
Assuming fuel sprayed out, not put a 5/8" socket on the bolt in the center of the blower wheel.
Take a small wooden dowel , brass punch or aluminum rod about the size of a pencil and use a small hammer to very lightly tap on the plunger in the center of the IP pay very close attention to feel if it moves inward at all, or does it feel solid?
If it moved a little, the plunger was sticking.
If it felt solid, look closely at the plunger while rotating the motor slowly with the socket.
You should see the plunger rotating counterclockwise at 1/2 the speed you are turning the motor.
You should also see the plunger moving in and out about 1/4" or so.
If it is not rotating, your plunger guide is broken.
If it in not moving in and out, the plunger is sticking in the body of the IP.
Check this all out and then we will move on depending on the outcome.
