I read in the thread that you installed a new fuel pump but the first thing I would do is check the pressure. Very nice read btw and love that you and your dad together have brought it back to life.

Your starting problems may be with the cold start injector also know as the ninth injector. There could be a problem with it causing the hard starting.
Here's a link to an earlier thread regarding it -

Contact them and see about sending in your injectors and cold start injector for cleaning and testing.

Thanks for all the compliments and advice!
So I have a few questions:
Does anyone have recommendations for an inexpensive indoor car cover for the winter? yup, i used 2 old queensized sheets. then i got this:
http://pages.ebay.com/link/?nav=item.view&alt=web&id=180731374068
Chevrolet Corvette C4 6 Layer Car Cover 1984 1985 1986 1987 1988 1989 1990
The compressor clutches for the A/C locked up towards the end of summer, what are some recommendations for a new compressor/accessories that need to be replaced? Rock Auto has the cheapest and other CF vendors have it as well. FWIW We plan on using R4 because we have access to it.
What is the best way to clean up the wheels? I wet sanded all 4 and the drivers side turned out fine, but the passenger side where the sun was when it sat still look bad because of the clear coat.
------ check your classified for replacement salad shooters. i can buy 4 here for 100$. easier than refinishing. imo the 80's wheels make these cars look like....well... i dont like them. look up C6 wheels on a c4.
The radio (Bose) is an issue, as they all seem to be. It has been working better as of late, and the speakers sound fine when they get the signal but other times it goes out. Pushing between the ***** seems to bring it back occasionally or a numb in the road will do it. Is this an issue with the receiver itself? Ideally we would like to buy an adapter for the Bose and the new head unit and keep the old speakers in to avoid rewiring the system.
------cant help u here havnt attacked the bose. right now i use the mp3 cable and am working on bluetooth and a microphone for handsfree calling. all with factory head unit.
Where does everyone recommend the cluster get rebuilt? I have heard of batee and also looked into Keen Parts where it gets sent out through them for a rebuild. Currently the system flickers on occasion, doesn't light up at all(Did it for a week then stopped), only works when the headlights or marker lights are on (dim only, could see the numbers with enough sun), and occasionally works right.
----- batee is where id send mine. or id use the batee info and try to fix myself.
Thanks in advance!

The budget was supposed to be around $6000, preferably less especially when we were looking at Trans Ams or Camaros, but the total cost has been around $8000 so far. There is still plenty to do without going through a full restoration but the main objective has been to get the car to run and drive reliably.

As for some of the electrical bugs, I'd start looking at continuity and corrosion around connectors first. My 88 is a lower mileage car, always prospected from the elements, but I find stuff like this -
Intermittent driver's side door lock switch:
Faster holding a wiring harness ground point to the frame, inside the driver's foot well:
Here's the ground point:
After seeing the condition of that switch, I pulled all the connectors and switches for the driver's door to clean everything up. Long term plan is to go through the whole car with a little brass brush and a can DeoxIT.

So after a couple more good weather winter drives, the next and probably expected problem has arisen. The brake line going towards the rear underneath the battery from the master cylinder is leaking. It feels like there are two lines so we plan on getting the car up in the air to find the failing line. The pedal is still firm and fluid was at the low line in the rear cylinder of the master, so I topped that off and it has leaked more since Christmas, below is a picture. It is not back to the low mark yet, its still toward the top and has since slowed considerably. Heres a pic of the leak underneath the car

Gauge fix - batee! Get support. Get videos on YouTube.
Give this video series a check on diagnosis of the fuel injectors.
If you have the original injectors, they probably due for replacement. FIC has the best deal for a set of rebuild Bosch injectors.

After further investigation the brake fluid leak is from the seal between the master cylinder and brake booster. A new Reybestos master cylinder is on its way right now so hopefully we have time to work on installing that and bleeding the brakes. Thankfully theres been some snow to keep me from wishing i could take it out right now!
On another hand, does anyone have experience with the "Four Seasons" brand AC Compressor/kit from Rock Auto? It seems to be the most affordable option by far and is R4 compatible(I have R4 freon for the car). If not is there any relatively economical AC option to get it running again? The compressor needs replacing due to a locked compressor. Thanks to all!

On a side note, is there any chance you're doing a video on the 78 Silver Anniversary Vette from the for sale threat in C3? I've always liked that 78/79 style and with the Anniversary Package, 4 speed and L82 it seems to be the best of the best for those years.
Thank you! I see all of these great C4 projects that are fun to watch and learn from and it makes me want to make this car even better. Its a great car, especially when it runs and drives

That's a terrific save with this '85! Glad it found a good home with you and your father. Once my '88 is up and running this summer we will have to meet up (I live right across the river in Northern Kentucky). You planning on going to the Keep Open House July 6th?
Keep up the terrific work!
Later,
Lee
P.S. Where was your build sheet located on the tank?

The build sheet was on the side facing the front of the car(I think). Heres a picture if it helps

Neat project and thread. Thanks for taking the time to write and update the thread.
I like the color choice. I may have considered retaining the 2-tone, because 2-tone is just so 80's. My 85 is 2-tone blue.
Your intermittent, hot restart, rough running, issue may be the MAF sensor. The 85 is a one year only MAF, burn off module, and ECM. In 86 it all upgrades to the 165 ECM. The multec injector failures and hot start are well known. But only affect 89-92. The 85-88 Bosch EV1's aren't affected by ethanol. They can get dirty or clogged, but this affects hot or cold.
Interesting input regarding your trans cooler failure. I've owned my car since new, and have only change the coolant a couple of times in conjunction with other repairs. I only drive it a couple of hundred miles a year. But now I'm concerned about corrosion damage to the trans cooler. I have the 4+3. The overdrive is plumbed into the cooler. I do not want coolant in the overdrive. Parts for your automatic are available, parts for the overdrive, not so much. Thanks for making me think.
Last question: What part of the country did that car get driven Winters in? Pretty crusty. My hat is off to you guys that will deal with this kind of crustiness. I'm a Southern Californian. I seldom see this kind of deterioration.
Nice car. Be proud.

In regards to the two tone, I really did like the original two tone paint and one of my paint ideas was C7 blade silver over C7 cyber gray in a modern twist of the original. My dad isn't the two tone fan I am but after browsing C7 forums and looking at shark gray in person we both really liked the way the color changes in the sun. I am a two tone fan and saw a blue two tone 85 at the Cincinnati Cavalcade of Customs, which was pretty cool to see. Thank you for the kind words!
On another note, theres an almost identical car in terms of color, condition, problems and price on the local craigslist. http://cincinnati.craigslist.org/cto/5423686000.html

The car looks great. Looks like you started off just like I did with my 87 project by replacing the fuel tank. You got me motivated to get up and do some more work to mine. Thanks.
