Default 85 does not want to run

I took the vette out for a ride yesterday and on the way home it started missing. Well it limped home and I got it cleared out when I got home but when you put it under load it does not want to run. Help me out a little, I do not know much about fuel injection and that is why I want to switch it over to a carb

OK. I'll be first. What codes is it showing? Your 85 will tell you what ails it if you will but ask.

Your car will talk to you and give hints.....

Go out and buy a Hayes manual for the Corvette. It will be the best money you spend on the car. It is cheap compared to the Helms OEM manual but has most of the information you will need. BOOKS HELP.

The above will tell you that if you look under the steering wheel on the right you will see a cover, pull this cover off. There are electrical pins in this fitting. If you use a paperclip bent in a "U" and jump A & B then turn on the key (don't start) the check engine light will flash. It will start by flashing once the twice (code 12). It will do this three times. If there are any trouble codes stored in the computer it will flash these codes. The above manual will show you which are the A & B teminals and will give you a code listing and areas to check out.

Sometimes the code could be as simple as a wire off the sensor. These are area or systems to check out. If this (pulling the codes) has not been done in a while....there many be many stored. To clear the codes, disconnect the battery neg terminal for a minute and then reconnect.

Don't let the car run out of gas. This results in early failure of the fuel pump in the gas tank. An easy replacement, but don't go replacing parts when you don't have to.


Best of luck with your car.

Dang, I'd take this as a reason to learn about fuel injection personally. It's not too difficult really.

Why is it everytime someone on this board asks a question someone tells them to buy a manual instead of just trying to help em, is it because they really don't know themselves or do some of you have stock in these companies?

Because that's some of the best advice anyone can give. It can answer a lot of questions before they even get asked. Did you read past the first sentence? You know, where he goes into detail about grabbing the codes? What would you have liked him to do, "armchair" troubleshoot his problem for him without knowing any details? Maybe he should have photocopied his own manual and posted it on here? I can't even tell what the point of your post is, or are you just stirring the pot?

You have someone new to Corvettes and for that matter, perhaps wrenches. I did give him the best advice I could for this distance....
I didn't say go out and buy a book and look it up. I gave him answers and advice. I know where you are coming from with the response being one line.....go out and get a FSM. (end of response)


And no I don't own stock in any book companies. The Hayes manual is cheap, I think less than $20. A little reading can save you a lot of probems. They FSM from Helms is big $$$$ as compared to the Hayes. For the beginner the Hayes will answer and keep you out of a lot of problems.

You have to start by helping yourself first. Get a little knowledge and progress from there. I have five seperate Word files set up (alpha) of threads that I have copied and saved to these files for current and futrue reference. Some of these threads are no longer available. The Forum is a wealth of information. There are times when the book just doesn't answer your question or help. MSEVEN, TJWONG and others have helped me out when I was beating my head against the wall trying to figure out a problem.

I will sign off and go back to pulling the L98 out of my car.....it is suspended about 3' off the ground currently. Going to transplant a mild ZZ4.

-John

Where do I pick up the book? Thanks for the information I'm not new to turning wrenches as I'm a prototype build tech and we run a Pro Mod outlaw car here in Michigan. As far as fuel injection goes I'm just comfortable with carbs.

You could probably get it at any auto parts store or Amazon.com.

I grew up on carbs. If you had spark and fuel the car would run! I have had to learn about fuel injection. Lots of sensors and a computer controlling things. To get the clean burn that these cars are putting out and the great gas milage, it is had to think about going back to a carb. But hey, I still run one on my 74 Blazer and it runs well.

Welcome to the madness. There is a "search" function at the top of the titles. Learn and experiment with it. You can come up with lots of information.

This comes up about once a week. Allow me to suggest that the purpose here is to assist owners in keeping their cars in operating condition. The Corvette is not a Model A. Its a little more complicated than that. To attempt to talk anyone thru the various steps in troubleshooting is far too detailed. A cheap book will pay for itself many times over.That is why it is almost always the first suggestion. IF you are to get very deep into troubleshooting/repair spring for the Factory Service Manual. Yes, it will pay for itself during its first serious use. I have been here since June 1999, I can not recall a member ever being denied assistance. Sometimes that assistance isn't what the asker wants to here but it it is offered in good faith.
