Sounds like a good little list! I've never done suspension modification to my own car but I've got a list of people I've helped before. Looking forward to hear she's running good : )

Well I got the old fuel pump out. I definitely believe the pump was the issue. The filter was very clogged, everything is rusty, and the grounding strap was almost broken in half. Installing the new pump is going to take longer to install unfortunately. The pump is nothing like the new one. The pump bracket is nothing like the one in the sticky here and there is only one wire to the pump. The new one has two. I guess the old pump grounded through the housing somehow. I assume these are differences between year models. My car is an '86. I'm not sure how yet I'm going to convert it over to the new pump setup. Has anyone changed an early model car over to a later setup? Trying to figure out what I am going to have to do to get it working.

Edit: after some searching around I may be able to get it to work with everything if I can clean all this up.

Here are the pics of the old pump. Its pretty bad :shock:

Here you can see the partially broken wire.

Alrighty the pump is back in the car. It wasn't to bad to fit it after I got my direction right. Now I'm just waiting for the battery to charge up to try and crank her up.

The new pump. I had to change the pipe clamp to a zip tie because the clamp was too big to slide into the tank. Took as much rust off as I could get and clean out the pipes too.

Any recommendations of how to clean out the tank? I looked down in there and it had a good amout of crud in it.

Well the car won't turn over. Just some nast clicking and buzzing noises coming from the starter area. The battery is fine with the appropriate voltage. So it sonds like the starter or starter solenoid is bad. That car hasn't been cranked for a little while.

check your engine ground strap and that the battery is connected TIGHT TIGHT TIGHT. Clicking means the starter is trying to work but not getting enough power. You can also try hitting the starter with a jack handle or something.

Side note, that old pump looks FIIIIIIIINE

I'll double check everything but I'm pretty sure its tight. I was going to try a few good raps on it. I was wondering if it was corrosion built up in the solenoid from sitting a little bit. Might have to add another engine ground or two just to make sure uts properly grounded. I'm not sure my rigged ground is good enough.

I was kinda shocked when I pulled the old pump out. It was quite nasty.

That pump was bad, lol. Based on the amount of rust on those tubes the tank must be nasty. Is it real rusty, or full of varnish?

The tubes cleaned up pretty well. Mostly scale. I don't thing the tank itself is rusting but there was alot of junk floating around might be some loose rust floating but there was some other guck that looked kinda slimy.

Must be water in the tank or something. I don't think gas corrodes metal like that. So weird.

but yea, I always have 2 grounds on my motors. Always.

I didn't think gas did either which is why I thought it was odd. Is there an easy way to drain the tank?

Passenger's side of the gas tank, there's an allen bolt thingy in the tank. You can drain that way. Won't get any big chunks out as the hole is too small though.

Alright. It probably would be a good idea to drain it. I didnt see anything huge floating around. It would probably work alright.

Also on a side note. I may need a new battery. It had the proper voltage but I noticed that one of the battery posts seemed loose. Like it wasn't secure from inside the battery.

I know :(. When I bought this one a couple years back I think it was around $80-90. But from searching around it appears that prices have gone up since then :shock:
