Here is a pic of my 'patch.' Some of the vines were growing up against the a/c unit, so I detached them and tried to accommodate them along the soil, which I also had just done this morning. Thanks again!

I haven't done pumpkins yet, but the vines are similar to cucumbers and I had to do that with my cucumbers several times this year during peak production and they did just fine. They are struggling now, but not resulting from re-positioning them.

First of all, it looks like you're trying to grow in a half full small planter. NOT!
Pumpkins need a LOT of room and a LOT of nutrients! Also a LOT of water!
I would say that each pumpkin plant needs at least a 10x10' area to get a few pumpkins. For giant pumpkins, I'm thinking a 10'x20' per plant area is what we had before. We grew them in about 50% horse manure mixed with our regular soil.
For the giant pumpkins, start in a pot, then plant when the 3rd leaf appears. The direction the 3rd leaf is pointing is the direction the vine will grow!
Happy gardening! Nancy

The leaves of your plant looked like they were not getting enough direct nu-shaded daylight. They looked small and spindly, and a bit too yellowish in color despite the miracle gro you used on the plant. Your soil(mulched) looks great though.

they look like they are suffering, could be due to them being in a planter, they would do heaps better planted in the soil proper.

We have re-positioned our cukes, Cushaw, cantaloupes and summer squash with no problems. it may take a few days but the plants figure out which way is up! The Cushaw grows over a foot a day, so we have been training its direction every morning. We have been using landscape pins,and just move the pin forward. I agree with Nancy, lots of room, nutrients and water. Also, the warm air that is being discharged from your compressor is going to evaporate more water from your planter than it would if it were not so close. You will need to keep a CLOSE eye on it.

The thing is that even if you were able to turn the things around and perfectec you pumpkin vine, I don't this they will produce any pumpkins this year.
You are in Zone 6 and the gardening season is down the hill. Probably you will get a frost in 6 to 8 weeks. Even if your pumpkins sat fruits a week ago, they will have no chance to get anywhere. From the picture, I can tell that you started your plants, way too late to begin with.

But on the other hand , it is good to know what has happened and what can be done better the next season.

Nancy hit it. That small planter is no good. They need depth for the roots and space to run.
