What a bummer gridlock. 6g in service. Please tell me that GM didn't make a car that with under 40k miles could need 6g in service repairs.

must have been a pretty bad pre-service inspection.. for $6k (at least doing it yourself) you can replace almost every moving part in these cars..

Yeah, I would think so. They never did fix the damn HVAC backlighting problem. I have never heard of these gas tank issues.

a quick search here finds plenty of threads on it. something cracking or leaking gas/vapors.. there's a ton of people raising hell and complaining to various safety/regulatory organizations. has to do with the EPA required changes in '03 models.

Because of the efforts here on the forum,GM had to make a commitment to repair at no charge the very limited number of cars that were affected by the bad tanks.

Grim...is there a post somewhere outlining the problems you've had? I just picked up a very low mileage 2002 Z and plan to do valve springs and complete fluid change out as PM, but not really expecting anything else. I do all my own work and believe I got a solid car, so I want to learn about your ordeal.

Here is a general list of what has happened to my 40K mile C5Z in a bit over 4 months of ownership:
Replaced all fluids in the car (expected this)
New set of tires (expected this)
Alignment (corner balanced and lowered it on the bolts when this was done)
Replaced all belts and tensioner due to belt whine
Water Pump
Valve Springs
Clutch
EBCM
EBMC Connector Damaged- Delphi no longer makes the pins required for the EBCM connector. So the only way to get new pins in to find these pins out of a salvage car. To do this, I had to buy a whole used harness. The seller was unwilling to just remove the pins or the connector. Then you need to actually add these pins and rebuild the connector. I think there are 32 pins or so, so that is a lot of soldering!

that list cost you almost $6000? find a new shop..

sucks about the EBCM. ive heard of that giving people headaches, but i also heard there's a company online that rebuilds them for cheap? just pm'ed the person that told me about it, i'll post back here.

What looks unexpected here in my view would be the clutch, water pump (did it fail? leaking?), EBCM and possibly the valve springs, which we all pretty much expect should be replaced on the LS6.

The other stuff would be normal, I mean you knew the car needed tires when you bought it, right? The belts, fluids, alignment and corner balance are all normal maintenance or PM.

Not trying to dispute your post, I mean you spent what you spent, just trying to divide the unexpected from the expected. Also, a lot of us here do all our own repairs, which has a profound impact on what is replaced and what you spend to keep your Z running.

Hopefully you can stop spending money and drive your car for a while. Best of luck!

I agree with pretty much what you said. I expected to have to put $2,000 in the car after I got it. It has cost much more. Water pump was leaking. I would love to do my own maintenance, but I can't because I am disabled. I used to work on my own race cars back in the day.

Tell me how you are going to get all the above done for much less? Remember I didn't just need to have my EBCM repaired, but I had to replace a damaged connector. To do that I had to buy an entire Corvette harness to get the pins and pay someone to solder them in. We are talking about $800 on top of the EBCM repair. Tires were $1,100. Clutch is going to be just under $1,700 this Wed. Alignment, corner balancing, brake bleeding, lowering on bolts was around $600 (slightly expensive, but the best shop in the area by far.), valve springs $800. That is $5K right there. On top of that I had all the fluid, belts, leaking water pump, tensioner, etc...

So yeah, this cost nearly $6K, and I am using the top shop in the area for corvettes that charges $99/hour. And I drive over 2 hours each way to just get to this shop each time I need something done.

On the waterpump, did that fail? 40K is way too early for a water pump failure. A lot of the time shops take a shotgun approach on repairs, "while we have the belts off and the front of the motor apart, we can save you labor on replacing the water pump".

The tires are a solid hit on these cars, unless you put cheapies on, that alone can chew up $1200-1500.

This truly a shame. The terminals, seals, etc...for both connectors on the EBCM, are available from Power and Signal all day long. I do admit, it does take some research to find the connector system components......you just have to be willing to do it.

This was researched before I went through it. There are two different connectors that work with the EBCM. Depending on which connector you get, you need to use a different pin. The one type of pin is unavailable from Delphi. If you have some sort of information that says otherwise, I would love to know. I worked with forum member RichierichZ06 who is a Chevy Dealer parts manager on trying to figure this out originally. I was also told the same thing by the guys at GM Parts Warehouse.

As you probably know, there are two different connector systems (combined) for the EBCM. One is a 29 way (small terminals), and one is a 7 way (large terminals). Depending if you have an early or late production 2003, will dictate which 7 way connector you have, while the 29 way connector remained unchanged. From a quick search, it appears that both Mouser and Power and Signal stock the terminals, and the part numbers are active. I also noted, that even though the part number of the 7 way connector changed (early v/s late production), the terminal part numbers remained the same.

Early production 7 way: p/n 15318099
Late production, 7 way: p/n 15401425
All production 2003, 29 way: p/n 15356700

I discussed this with both the guy Bill Curlee sent me to and RichieRichZ06 and both told me that there are two different versions of the large connector. Depending on which you get, determines which type of terminals. Who knows, maybe these guys were both wrong. But I know Rich does this for a living, and he said he couldn't get the parts. I can send him a link to this thread if you really want to get into it deeper I guess.
