I'm guessing the old gear-style fuel pumps don't rotate very well when cold? I know this factory pump has been on its way out for a while. But now that its in the 40s or so, when i jump it via the relay wiring (orange to grey) i just hear a thump in the back. Like its trying, but then no thanks.
If anyone has an idea how to just get it to turn enough so I can get it started and 2 blocks away to get it replaced. I really don't want to take the suspension apart just to get a pump out.

 

First, a 1992 TPI most likely has a turbine type pump, not a gear pump.

Second, 40°F (above zero, not below) isn't considered "cold" by any stretch of the imagination. I've had older GM EFIs like that start unassisted at -44°F, and fuel pressure was the least of any concerns.

Next, if the pump produces a "thump" noise it may either be loose in its mounting or dead-heading against a plugged line or filter. Can you measure a current readinf while it is trying to run?

 

I hotwired orange and grey and put an amp clamp around it. I was getting 12 volts and about a tenth of an amp. I let it sit for about 5 seconds, then suddenly it sounded like it turned a little bit. So I jumped the terminals again, and no spark. 12 volts still, but no draw. As if its just completely dead now. The fuse over by the battery is fine.
For what it's worth, the car isnt even registered or insured anymore. Its got like 88k miles on it, and has been sitting in the garage for a couple of years. I dont drive it because I cant drive anyway. I start it up once every couple of months to keep things wet. And it just so happens this time it decided not to function.
The filter is new, but the gas is old.

 

I’ve had 3 electric in-tank fuel pumps on GM vehicles go bad over the years. They work and then one morning, they just don’t and that’s it. None of them gave any warning and there was no reviving them. Replacement was the only option.
