please keep me from scrapping this project.

i am not trying to do anything big just get this damn car put together. problem is it was partially taken apart, lines cut or missing, random by-passing and other things that are so ghetto-rigged i don't know what to do. it was even missing the steering wheel. i have a collection of 850+ pictures i copied of this site. read numerous threads and copied some i think that might help me.

problem is that Haynes manual does practically nothing to help if you don't already have the car put together right, right before you start working on it. i am tired of reading "make sure to mark everything you disconnect"

I need pictures of mounts for the vacuum solenoid for the egr or what ever that is... i basically need pictures for every damn thing in the engine cavity. there are more problems than i can think of. i need to go junk yard diving for everything i need. it is just when i find a model with the v6 it is always taken apart.

any routing information of anything and pictures of everything would be nice. please help in anyway you can.

i am without a working car and i am trying so hard to get this thing working so i can finally drive again. once i can get it put together properly i'll try to gather the money needed to make it run then run better.

sorry about how this thread is set up but i am at the end of my rope here. i keep trying and keep running into more dis and misconnected lines. it is hard to try to figure this out without proper references.

please help.

Re: please keep me from scrapping this project.

These old engines don't have to much to em. Picking out one problem at a time will get you a much better responce. If your looking for a vacume diagram I'm sure someone has one. But try to ask for oe thing at a time, your first post is going 10 different directions at once.
Wiring would be the main thing that I'd be worried about. making sure you have a compleate (or at least functional) wiring harness for the engine, lights, etc is essential.

Re: please keep me from scrapping this project.

the wiring for the most part seemed ok. i just had to redo the plugs for the relays and to get the relay i was missing. i still need to check under the dash to see if the mice chewed any other wires. but so far that seems ok.

the main problem is i am missing mounts around the egr and am not sure what they look like or where they go. and the emissions were a big problem but i think i have it figured out for the most part.

now all the other vacuum hoses and the like... i have no clue. i am missing the coolant lines under the throttle body for sure, and have no idea where they would go otherwise.

Re: please keep me from scrapping this project.

If Haynes manuals were printed on 2-ply a$$wipe at least they'd be good for one thing...
Get yourself a GM Helm Service Manual for your year/model car. They're expensive new, but usually $20-50 on Ebay. The upside is that they have wiring diagrams, vacuum diagrams, and so on that actually apply to YOUR car.

Re: please keep me from scrapping this project.

I know this is blashpemy on this site, but if you are without a running car, and need one, it's probably in your best interest to find a different car that RUNS for $500, instead of giving yourself an ulcer trying to get this one running. In the end, it will probably cost you less money. Just my two cents

Re: please keep me from scrapping this project.

You might want to invest in a GM service manual. I got one off ebay a few years back for my car for about $40. I think it was worth every penny.

Re: please keep me from scrapping this project.

If you can't find the stock way to do it, make you're own way. Vent the valve covers to the atmosphere (with filters), block off the EGR and EVAP, and ditch the cruise control (if equipped), bypass the throttle body coolant lines (you probably would do that later anyway). Whats left for you're vacuum lines now that everything's blocked off or removed? Ah yes, your brake booster hose goes on the back of the intake at that "T" and there's a vacuum line that comes out of the harness (near the HVAC) that needs to be connected somewhere.

Re: please keep me from scrapping this project.

The 2 outlets that should run coolant to the TB, get a piece of hose to connect them and bypass the TB if you live in moderate temperatures.
Can't help you with the EGR. The digital one in the 3.1 is in a totally different position.
T believe the plenum has 3 openings for vacume lines on the back of it. The big one is just for the Brake booster, the one on the other side of the T gors to the charcoal canister, and a few other things, and the single small ones is used by only the MAP sensor.

I wouldn't condone doing things incorrectly. Even if it "works" now. If a problem arises down the road its going to be that much harder to diagnose.

OP, PM me with exactly what you need as far as diagrams and I'll check AllData. Be sure to include year, make, model, and engine size.

my problem is i don't have a lot of money. i can nickle and dime this one for some time and it really shouldn't cost me much to fix the rest. still need gas and fuel filter and coolent maybe a few other things. but i got oil and oil filter waiting. a new battery waiting. and a couple of other things.

Re: please keep me from scrapping this project.

Hang in there. for the most part your on the right track. Getting to know your vehicle. Its a major step believe me.

also take the advice get the service manual. If you have a library they will have one or can get one. Make copies of the wiring and vacume diagrams. Chilton manuals have them also. plus exploded views of your engine,parts and links. If you can find your model year of car on a car lot grab your camera talk to the salesman and snap away. look on the boards for any car clubs or folks in the region. You would be surprised at how close and willing to help many of us are.
Last but not least break your project up into systems.
I.E. Wiring. Vacume. Fuel, finish each one before you start the next. And DOUBLE CHECK EVERYTHING

Re: please keep me from scrapping this project.

I'll throw this out there, but perhaps getting the Helms GM Shop Manual? I have one for my '84 Camaro and it tells you just about everything about the car. It may help with the occasion pic of a working one.

Re: please keep me from scrapping this project.

I agree with what the others have said:

1. You can't use a Haynes book for that- you need the GM/Helms service manual. Both manuals have their good points (GM/Helms wont' tell yiou how to remove the rear axle if you've never done it before), but when you get in-depth, you need the GM book. (I have both and use both as the situation requires, kind of like having both a spoon and a fork)

2. I'll be one of "those guys" and say, scrap the project, buy a car that works and chase the f-body dream down later. Unless of course you don't need a running car. What you bought sounds like a parts car; I definitely wouldn't have bought it unless it had something I needed for my car (like a rust-free body or perfect interior). Was this thing running when you got it??

At this point it may be more of a safety concern than anything.

when i got it, it wasn't working. i got it for only $200 because one of my servers, ex boyfriend have been on her *** about getting it out of his yard. her ex is one of the people who think he can fix things but eventually kills them. back when i was 17 i had an 78 monza waiting for me but i had to sell it to him for rent money. it is now not much more then a pile of rust and i now regret that choice.

i really don't got money right now but i can scrounge up $10 here and $20 there. the AC supposedly works since he got it a new compressor, the interior is really nice no cracks on the dash and free of rust for the most part. it can use more new parts and when i am in a better financial situation i'll be buying new mounts and such. i am hoping to buy a new engine and hybrid build it with new parts and gather new performance parts and overhall the whole thing. even redo the wiring and interior. i have big plans to custom everything. i'd save all the parts i take out because i am hoping to restore another one later in about 3 to 6 years if i can find one. but only if i can get a t top or convertible. this one is base model everything.

but again right now i just am working on getting it running do drive once and a while.

Re: please keep me from scrapping this project.

definitely don't give it up. sounds like a good car especially for what you've paid. just don't worry about the extra stuff, just the things that make the car run and drive. that's why i recommended simplifying the way the car runs when it's possible. deleting emissions is a great way to do that.

Re: please keep me from scrapping this project.

With all that rigging it sounds like a nightmare. My concern is, if it didn't run when you got it, it might never run, did you ever do a compression test? But it sounds like you talked yourself out of scrapping the project, definitely get the GM service manual. You might consider buying another f-body that runs to use it as parts to fix yours.

Re: please keep me from scrapping this project.

Sounds like it will be a good DD once fixed up. Not every F-body needs to be show car quality. Even base models with V6's can be very fun and cool cars.\

Good luck with the project! Any technichal questions be sure to ask. I'd love to see some pics of the car as it sits now too, body, engine, interior, etc. Pics usually help me and others make recomendations and such
