I am on my second Passiflora ! the first one P Caerula died on me. I decided to dig it up and put it in a pot in my greenhouse. Lo and behold it has sprung into life!! I then bought a second to replace it, this was the P Victoria. Also this looks like it dying on me. Just been out to inspect it and it has white fly (I think )on the back of the leaves, so just give it a spray. It is on a south facing wall but is partly sheltered from the sun. Can anyone suggest anything. I have got room on an east facing fence if need be.

Passiflora caerulea is the only fully hardy one - clearly yours hadn't died, but had suffered from the last very harsh winter we had. Procedure with those is to leave them insitu, cutting back any dead stuff by end of May if no growth, and wait and see. P. Victoria is said to be hardy - by the sellers - but the growing info I've come across suggests it isn't fully hardy in the garden, so you will need to either protect it in the winter, or take a chance and see if it survives. The infestation you describe may well be aphids of some sort, and spraying with an insecticide is the right thing to do.
