Hugh:

If you got air into the IP, it can take quite a while to get out. Hold the throttle wide open when cranking to test, next to nothing is about correct at idle position -- even full throttle won't deliver a lot at cranking speed.

Also, check the suction line from the tank to the lift pump -- this line often goes bad under the fabric cover, and will allow air into the system instead of fuel. Fuel won't leak out, either, it siphons back into the tank if the car is level. Hose will be damp with fuel.

I cannot think of anything else you may have disturbed that would cause you trouble, unless you have the linkage messed up so that you are forcing the rack completely closed and don't know it -- check for proper linkage travel at the IP. If it is stuck at idle, you may have trouble getting it to start from fuel starvation.
