Does the bolt need to come off? Why would the plug receptacle need to come off the firewall?

I'm sure this plug has never been pulled.

The bolt stays with the connector that you are removing.....the female side.

If it's possible, you can spray some WD40 between the 2 connector bodies and let it soak overnight. This might loosen the pair enough to get movement. Once it starts moving, you'll be able to get it apart.
No, WD40 won't hurt the connections. It's actually an excellent terminal cleaner.

EDIT: Shit....that big ass connector doesn't have a 7mm in the center of it clamping the 2 together?
I just looked at the pic closer.

Yes it does. You aren't going crazy Scott. lol Look at my second picture, you can see the threaded part of the bolt on the front section.

Well I wonder if that was my problem all along!

Phew! I feel better now. lol

Jack, does the connector back itself out to an extent when you're unbolting it (it should), or does the bolt just seem to turn?

If you're talking about the one hiding in the black plastic tunnel, I was going to ask what size and type of driver it takes, because I can't see what's in there. I tried a phillips, but that didn't seem to engage.

It should be a 7mm

I ordered some electonics cleaner and sprayed the connections down good. The plug came out super easy once I removed the hidden 7mm bolt. Now I can rule out this problem. Would a bad crankshaft position sensor also cause a miss?

The Riv's been running fine since cleaning the electrical connector, but I'm planning to address the other potential problems. So, here are a couple parts questions -

Crankshaft Position Sensor -

What is the difference between ACDELCO 2134665 and ACDELCO 213151

The latter is $23 more, but has no extra features listed. The former appears to be the same as STANDARD MOTOR PRODUCTS PC30, which is another $5 cheaper.

Then there's ACDELCO 19326459, the cheapest AC Delco option.

Going by the descriptions I'd think the Standard PC30 is the one to get.

Ignition Switch -

There's a "cheap" AC Delco - ACDELCO D1482D and an expensive AC Delco - ACDELCO D1438F. The expensive AC Delco appears to be a rebadged version of the STANDARD MOTOR PRODUCTS US260 Both AC Delco's have a 12 month warranty, but the Standard has a 36 month warranty.

I'm thinking either the cheap AC Delco or the Standard, but probably the cheap AC Delco for $55 less.

I wouldn't completely dismiss your initial hunch of the failing fuel pump. Mine went slowly, stalling once every few weeks, then more frequently. If/when it happens again, if the engine turns over but doesn't fire, pop the trunk and hit the center floor firmly with a blunt object. If it then starts, probably is the issue.

I am struggling to remember when my original fuel pump failed. It was ages ago. My GM dealer installed a Carter (SShhh - factory pumps were available but had a poor reputation with the mechanics and the Carters were cheaper) and I have not had to mess with it since. Thinking about it, that was more than 150,000 miles ago...
