I understand that they are a business and the point of a business is to make money. Every forum post/info I could find through google indicated that all it took was going to the dealer with the VIN and maybe the serial number of the radio, they punch it into a computer and have the security code for you in 3 minutes. No mention of hooking the vehicle up to the diagnostic computer or anything like that - so am I getting taken for a ride by this particular dealership, has the process changed or are the internets lying to me?

You may have gotten the incorrect details from them, or maybe they are tired of explaining that the minimum charge for 15 to 20 minutes worth of work is 30 minutes. Understand, that just because it only takes 3 minutes at a computer to retrieve the number, that doesn't tak into account the time to talk to you, bill, collect money, have you there, verify that you are the owner of the car, etc, etc.

Are you saying you have a lockable draw pin (so people can't steal the hitch)? If so, that's tho stock. If you find the manufacturer on it you could call them and see if their keys are universal, or if they can get you another. Or you can do the easy thing and just stop by a welding shop and slip somebody $10 to cut it off and then go get a new one.

Not sure what style you have....can you grab a picture of it?

Most I've seen are just bent at one end, and have a notch for the lock to engage with on the other. If you cut either end off of those, it will just slide through.

I can't imagine that there would be anything keeping it from sliding through inside on yours either, as putting any sort of mechanism through that pin is just going to serve to weaken it.

Well, I have a heated garage to work in, and basic tools, I think I'm just looking for an excuse to buy more tools and such. I have a decent mechanical aptitude, but the only thing really giving me worry is that parts might be hard to find, especially electronics stuff, and even moreso coupe specific parts.

That's just the way it works...sometimes it takes a while to get parts. Sometimes you pay way to much when you are impatient/desperate.

With the attitude you have about looking for excuses to buy tools and if you have something else to drive, even if it's just a beater you'll be fine. Find the model specific forums for those things and get to know the guys who have parts cars. Figure out where you get parts you need new cheap (Pelican Parts will probably be on that list). Accept that it won't always be pretty, and won't always run, and that you might need to wait on parts for a while and drive something else.

If you can do all of those things, as well as pay attention to details, sounds, and smells, you will likely be happy and never left waiting for a tow truck. I'm doing all of those things to daily drive a 25 year old sports car. I have better/newer/more expensive cars to choose from.

Do you have emissions and/or inspection in your state? If so, a check engine light likely means you aren't going to pass.

The head gasket...."behind the water pump"? It's got a bad head gasket that needs to be changed, and he's filled it full of snake oil. This is why he's selling it. It's an $800 job to repair. And then you need to flush the crap out of the cooling system that he's been putting in there so it cools properly. And hope the heater core isn't clogged up. And the radiator. And while you do that job, it only makes sense to change the water pump and timing belt. Again, this is why the car is being sold.

If you don't know how to evaluate and/or repair these things, those are gigantic red warning flags telling you to run away.

$1,500 is probably a fair price, but understand what you are getting into. This car should be worth $800 more in good condition. Which happens to be the price of the head gasket job which you will likely need.

Are head gasket failures common on the 2.8l 12v? The guy kept saying that he was sure it was the water pump gasket. Unfortunately I didn't really have a way to verify that. I am kind of annoyed that he filled it with stop leak, too. I don't think I'd have too much of an issue doing a head gasket job myself, but finding the time to do it will be difficult.

It's not like its some epidemic problem, but someone who thinks stop leak is a good idea is probably the same kind of guy who thinks he doesn't need to change his coolant. At that age, you're probably looking at some nasty stuff that's in there (not even counting the stop leak) that has eaten things up. If the same coolant is in it, you can pull a pH test strip to see how close to 5 is probably is.

So, even if this is just the water pump gasket, why would it be eaten up and not the head gasket? Shoddy replacement? Never replaced? Bad coolant change intervals (meaning the head gasket is junk too)?

The point is, you don't know, and there is no reasonable way to find out. When you don't know, you have to make your offer price for the worst case scenario, and expect to own that scenario. Anything else is setting yourself up for disappointment.

I take a very conservative view about buying. If it can't be verified, I assume the worst and offer accordingly if I'm willing to purchase something with that worst case scenario. There are too may other cars out there for sale to compromise on this kind of thing.

I mostly just want it to diagnose engine codes so I don't need to do it at the dealer.

Well, VCDS doesn't come as a smartphone app as far as I know. But you use an appropriate OBD-II to USB cable, or an appropriate OBD-II bluetooth dongle.

With the bluetooth dongle, you could run VCDS on a laptop with bluetooth, and use the same dongle to connect to a smartphone with an app that will read at least basic OBD-II codes and provide live data.

If there are ANY good parts on it that is UNREASONABLY LOW. $400-500 is what you should be expecting from a scrap yard that will be coming to you to pick it up.

People who are interested in a parts car like that are going to want a lot more information about things than the average person, and are fewer and further inbetween. So it could take some time to juice $2-400 more out of it. Up to you if that's worth the effort.

I figure the next step is to replace the relay, but I thought I'd ask here before I buy a part I might not need. Do I need to disconnect the battery when I replace the relay? I didn't for the fuse but maybe I should have.


It is pretty unlikely that a relay is going to blow the switched load side fuse. In fact, I can't think of any way that would happen short of some very odd type of malfunction in the relay itself that I've certainly never seen.

You need to be checking the amperage draw on the plugs. Sounds like one or more are way over, or you have a partial short somewhere in front of the 50 A fuse.

And no on needing to disconnect the battery on either of those.

Motronic
Nov 6, 2009

Opensourcepirate posted:

I was thinking maybe the relay went bad in some way where it's shorting internally. Like I said, the plugs are all within .1 ohm of each other and within spec. I looked for shorts in the engine bay, but the harness wires very quickly join a bunch of other wires in a big bundle.

I'm not sure how I'm going to check the amperage draw if the fuse blows immediately. A relay is only $50, so I think I might just see if it fixes things.

Edit: To be perfectly fair, I'm not positive that the fuse blew immediately. The check engine code came back immediately (I had cleared it when I replaced the fuse), and when I checked like 6 starts later, the fuse was blown.

One would start by checking the amperage at the fuse when the plugs are on. If it is high, you move on to checking the amperage while moving as much of the harness as possible to see if it changes. You then go to checking the individual amperage draw on the plugs, which is most easily done leaving your probe in exactly the same spot and leaving only one plug attached at a time.

It's your money, so if you prefer throwing parts at things rather than doing diagnostics that is your prerogative.

This is probably a stupid question, but do I need to worry about damaging my multimeter when I try to measure 50+ amps?

Not a stupid question at all, but the answer is simple: you need to see if your multimeter is rated for that amount of current or not. I don't know what you have, so I can't tell you for sure. A clamp style is often easiest if you can isolate a run of the wire (or make a wire extension for the fuse).

Opensourcepirate posted:

I'm confused about how the plugs could be drawing too much power; shouldn't that be determined by their resistance?

Not really. Measuring resistance in a static state is not going to show you what they are doing in operation. You may be getting a huge amount of inrush current when they are very cold which is blowing your fuse (resistance typically increases with heat, and lowers the amp draw). You might be partially or dead shorting a connector when they start to warm up. You may have low voltage to one due to a poor connection, which will increase its current draw. I'm sure you get the idea: amperage is a live reading. It shows you what is really happening when the circuit is in operation, rather than testing one single component and calculating what it SHOULD be doing based on that reading.

Also, I should mention that cruddy terminals for the fuse, relay, or plugs themselves will do this. Make sure they are all clean before calling a part bad. Protect them with dielectric grease to keep them from getting cruddy.

Parts are easy to find for the most part. At least the things that are likely to keep you from driving it. Fiddly bits for the interior or similar may be a different story. You just need to get used to the idea that you can have it now/tomorrow at an exorbitant price (overnight shipping or a dealer), or you can wait for shipping from most likely CA. I use pelican parts, and I'm on the east coast, so I know I'm waiting.

If you're OK with that, and the fact that a parts still cost real money compared to a chevy ($100-200 water pump ordered, $300 at the dealer as opposed to a $15 pump from AutoZone that you can just drive over and pick up right now) you'll be fine. But not everyone is able to wait a week for parts, so the bills stack up.

GnarlyCharlie4u posted:

I'm sorry I should have specified that it ran fine. I didn't drive it. And the coolant is in fact NOT getting into the oil. It's not a ghost leak, it shows under car but only when running. That's what makes me think it's the water pump leaking. Possibly radiator.

If I recall, the water pump is driven by the timing belt on this motor. So here's the issue: that pump seizes and your valves meet your pistons pretty quick, as the belt is going to tear if the pump stops spinning. I would consider part of the cost of buying this car a water pump and timing belt job, along with hoses, a serp belt and possibly the radiator. Figure out what those parts cost, what ill will cost you to get them installed (or your own time), add that to the asking price and decide if its worth it to you.

Since you obviously know where to get parts at the right prices, know you'll wait, and can do the work I see no reason NOT to go for this car at that price or a bit less after driving it.

What else is likely to go wrong? Electronic fiddly bits inside. At 140k and if they haven't been done already, ball joints and dampers. Probably sway bar bushings. I'd want to get each front wheel in the air and see how it feels.

Take the ignition switch back out and turn it manually. If the car still doesn't start (with a key in the ignition for the RF part) it's not the lock cylinder.
