Actually, I tried the charger directy on the bolts and with the negative lead on the chassis. I got the same result both ways. I will certainly take the battery back to Sears for a check. It is a DieHard Gold, so dealing with them should not be too hard.

I go to start the 90 vette today, and I have absolutely no electrical power. I originally thought the I had left something on and drained the battery (6 months old), so I hooked the charger up. The charger immediately shows a full charge. I went to see if I had any power to teh car with the...

Does anyone have the part numbers for the two o-rings for the supply and return fuel lines for a 1990 Corvette? These are for where the fuel lines meet the fuel rail. The set I got from Advance include one larger one (that appears to fit) and one smaller one that seems way too small. The lines...

I got a really great deal on a 1990 fiberglass top, but to make a long story short, it was an early model top. I see from searching the forum that it is possible to modify the mounts on the body to retrofit a newer top to an older C4, but my question is whether or not it is possible to modify...

Speedmaster... I don't see a fuel pressure guage on the Harbor Frieght web site. Is this what you are referring to?... http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=92699

I have an occasional hard start condition that seems to only happen if I let the car sit for about 1 to 8 hours after driving. If it sits overnight, it starts right up. I am guessing that my fuel injectors are leaking down until the pressure is gone. And I think it starts normally after a...

Interesting development... I removed the air intake from the throttle body and it started right up! I have checked for any type of blockage and there is none and the filter has only a few hundred miles on it and is very clean. When it is running, the exhaust smells like it is running a bit...

OK - the very faint whine after the car turns off appears to be from the brake master cylinder and it sounds like it is internal to the mechanism. I do not beleive it is related to my problem. So next is to check the IAC valve. Is there a way to test this to be sure it is the failed...

Ah... the dreaded vacuum leak. It looks like I have my work cut out for me. Do you happen to know if there might be a diagram of the vacuum lines posted anywhere? Thanks again, Rob

Thank you for the responses. I unplugged the TPS and there was really no effect. If anything, it might had run a split second longer before shutting off, but it still not idle. I will take a look at the IAC valve after work today. Is there a way I can test the functionality of that? Also...

Well…. I have my first real problem with my car… I can’t keep it running. To preface, I last drove it the day before Thanksgiving and everything was fine. I went to start it today and it started right up as usual, but died within a second and then the starter just cranked… maybe a fuel...

Thanks LT4MAN, I knew there was something wrong here... it just looks wrong tucked up behind the body. I think whoever installed the Super Turbo's before I owned the car cut the pipes and they are too short now. I suppose I need to go look for a new rear Y-pipe. Please do send that...

I have decided to replace that overly loud, resonance creating mufflers that came on my car with a more stock styled exhaust. I decided the on the stock-style aluminized mufflers that Mid-America sells. I love the way it looks and sounds, but I am not sure they are fitting right. The ends of...

Thanks for your reply... Is the EVAP canister the same as the fuel vapor canister? I have checked all the lines from the canister to the tank and they are free and clear. So I am now assuming that my problem lies with either the canister, the purge valve or the solenoid. I can get all...

Actually, my mileage is pretty good... It is showing 19.1 right now. But with a few 30 mile highway round trips to work, it is usually around 21.

Another Tidbit of Info... I think this is unrelated, but I'll throw it out there... After searching the forum thoroughly, there does seem to be correlation between a fuel vapor smell and a hard start condition. My car starts within one or two cranks after it has sat in the garage overnight...

Well, I am still struggling with this.... The fuel vapor smell is really only evident near the rear license plate area when the car is idling and no where near the vapor canister at the front of the car. I have pulled everything back there and all the lines look fine with the exception of a...

I have a recently new problem with my 1990 Coupe that I am having a heck of a time tracking down. After driving the car, and parking it back in the garage, I have a very strong fuel vapor smell. It seems to be strongest to the rear of the car, outside. The strange thing is that I do not...

That's unfortunate. It must be the other red used on the later models. I will continue to keep my eyes open for you. - Rob

jimmers, I think the main difference might be the color. The 1990 Red is flame red. There is a NOS set on ebay right now... http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=8039770566&ssPageName=ADME:B:EF:US:1 Now, I will continue my never ending search for front kick panel...
