Hey guys. I have been busy with other cars and haven't gotten back to this car yet. I was planning on going to autozone etc and borrowing theirs. Do they have one? Guess I will find out!

I have a friend with a scanner that will let me borrow it. I think Tuesday is when we will take another look at the problem. I have an opti bought just in case.

Little bit of an update and sadly not a good one. Took it over to my friends house, and tried a scan tool on it. The car started to run even crappier than before, and now will not start at all. Kinda just sputters and dies. Before this is would start to run rough and backfire, getting worse and worse. I believe that the opti finally took a dump and died, because I now have zero spark to the plugs. We will see what happens next

If anyone is still interested I found the issue on my car. Turns out the screws on the rotor inside the optispark had come out, and had fallen to the bottom. The rotor was then free wheeling until the plastic peg broke. You can also see where the rotor was misfiring super badly.

Wow! I'm really glad you diagnosed it. Gutting the T stat... yuck. I don't know why people do such retarded things either. Thermostats have been an important part of the cooling system for a long time. It's nice to have working heaters and for combustion temperatures to actually be at ideal.
I'm sorry you went through the entire fuel system. Was it the gauge being off after all?

1. The fuel pressure regulator was leaking, so it needed replaced.
2. The fuel filter was nasty inside, so that needed replaced anyways
3. The pickup sock was collapsed so that needed addressed anyways
4. The fuel pump? Well I'm sure that could have kept on, but after 20 years, might have needed it as well?
I'm finding out a lot about the car through this job. For example, all of the spark plug wires had been replaced with the exception of the coil wire. Things like that. It should all be back together shortly!

Check the bearing on your opti. If it is okay, then a new cap and rotor should do the trick.
If you act fast, here's a Delphi cap for under $26 from Amazon -
Failing to get that I would get a Standard Motor Products cap and rotor kit. I got one a couple of years ago for a spare opti I picked up on Ebay and it seems to be well made and heavy duty.
Use BLUE locktite on the rotor screws not red locktite.
Also check the operation of the opti venting system as per the manual as I don't know if the moisture inside is from your removal or a malfunctioning vent system.

With blue locktite you'll be able to disassemble/replace the rotor again if need be. And the screws won't come loose with blue either.
