1967 RS Duramax Camaro

[dslhtrdr]

simply awsome :thumb: just wondering 12v has a cult following wondering what made you come to the Duramax for this build

Simply put, the duramax fits much better. It is by far a more expensive swap, but in my opinion, a better all around motor for a camaro. Not to mention 2-300 pounds lighter.

Is the camaro finished yet!

I wish.

Sweet car!!! :thumb::woott: I love the part in the first post where you drove it till it started raining. That would be about 20 minutes here :roflmao:

The car had enough rust and rot that I felt it would have been a travesty to add to it with the rain coming.

I'm blessed to live in an area with awesome weather. This car will not be driven in bad weather, if I can help it. Typically it's dry out here from mid June through the end of October. Sometimes through fall and winter we will have dry spells where some folks bring out their hot rods, but those are few and far between.

Awesome build! Wish i would have seen this much earlier! You are blessed with some fine fabrication skills! I will definitely be keeping an eye on this build! Good luck! :woott: :thumb:

:thankyou:

I need some help guys. After a few weekends of working out some bugs and tying up loose ends, I worked on the Camaro all day today and couldn't get it to fire.

It's getting plenty of fuel. I'm 99% sure that all the air is bled out of the injection lines. After cranking it for 10-15 seconds, I cracked open the lines and a ton of clean fuel came squirting out. I did this 3 times. All of the lines are now tight, no leaks anywhere.

I sprayed a tiny bit of starting fluid (yes, I know it's a bit of a no no...) and it immediately ran, for 1 second.

I checked all my electrical connections, and all appeared to be good. Everything was plugged in, grounds were good, etc.

As of right now, I do not have the intake or intercooler plumbing fab'd up, so the maf and map sensors are out in the open air. This is leading me to think that they are not getting an accurate reading, therefore the pcm (ecu, or whatever you like to call it) isn't telling the injectors how much fuel to inject.

I tried scanning the codes with my PPE programmer. All it said was: C101, 0000, and 0600. I looked at PPE's website and it didn't tell me a whole lot about those, especially C101. I will have to hook up our snap on scanner that belongs to the shop and see what it says when I get a chance.

I'm at a bit of a loss, so I need some more experienced help.

I saw something about the C101 with the PPE could be the TCM has been fried from overloading the ground. Also saw that if you ground the case of the TCM it might start

 

[dslhtrdr]

There is no TCM in my case, because it's a stand alone. Unless I've misunderstood something along the way... The only control module so to speak is the computer for the Duramax itself in my application.

 

[adeso]

Has it ever ran? I think the LBZ ECM needs to talk to the TCM to be happy and start

 

[dslhtrdr]

To my knowledge, it has never ran since it was pulled from the donor truck, which was before I got my hands on it. I was under the impression that the ecu gets flashed when converted to a stand alone. I will have to call PPE on Monday to get some answers.

Also, just read on another forum that another lbz had a somewhat similar issue where the motor wouldn't run in a boat application without a PPE tune loaded. I guess I should have tried that, but wasn't sure if that was a good idea.

Can you disable all codes?

 

[paint94979]

I have efilive and can help you out if you need it... I'm in Novato

 

[dslhtrdr]

I can clear the codes and one comes back, I can't remember which one though. I'll have to write it down next time I'm with the car. I might try to load a tune on it. Not sure if I will get a chance to work on it tomorrow. Probably will have to wait till Monday...

A scan with efi would be sweet. If I can't get this figured out I might take you up on that.

 

[rickettzusaf]

Do this^^^

 

[paint94979]

Just to help rule tuning out we can disable every code just to see if we can get it to fire

 

[JoshH]

You need to make sure the VATS is disabled.

Couple teaser shots for you guys. More to come soon...

GAWD DAMN, THAT CAR IS HAWT

Keep on keepin on, you'll figure it out and get it started, there's plenty of guys here that know whats up, that I'm sure would like the opportunity to see your ride in person, and would like to be there when it fires up for the first time. I know if you don't get it, you'll get the help you need. Patience isn't always easy, but it's always worth it in the end.

has your ecm been retuned yet or is it still the stock tune from when you purchased it with the engine? Or has PPE had it & reflashed it?

If all grounds have been checked & its been retuned, I'm thinking the injectors aren't being fired for some reason... you could check this by pulling the glow plugs & cranking it. If fuel mist blows out, then my hunch is wrong. . Next I'd say you'd need to log while it cranks to see if its building enough psi to actually fire off. I wanna say its 3200 or 3500 but can't remember for sure. Also think it needs a certain amount of rpm but that's pretty low & if its cranking by a healthy starter, its probably sufficient.

I wish I could remember all of the required parameters the computer needs to see to fire the injectors & start but its been years since I've read those threads. The good news is that the info. & those that know it are here to help! Y'all will get it figured out! :thumb:

First thing that came to my mind too.

Ok. If I can't get it to fire on my own, I will try to get ahold of you. I appreciate your offer :thumb:

I searched around a little for the VATS and mostly found the VATS relearn procedure. I'm not sure yet if I can altogether disable it with my PPE tuner or with the shop's Solus Pro scanner. Those will be the first things I check when I get back to the car.

:thankyou: I should post the more recent pictures. It's most of the way together now. Trying my best to stay patient, I've been waiting for this for a LONG time.

I found the duramax on craigslist 5 years ago and traded the motor I had in the Camaro for it. It had already been pulled out of a truck. The entire harness and ecu had already been sent to PPE and turned into a stand alone, so whether or not they reflashed it or tuned it is unknown to me. I will have to call them on Monday to ask.

When I hook up their tuner, it tells me that it's current tuning is stock. I might try loading a tune onto it after trying to disable the VATS if I can. I will also pull the glow plugs if these attempts don't pan out.

First thing that came to my mind too.

I appreciate all the tips guys. I will try them all and see what happens.

I'm banking on it still being stock tune & therefore needs the vats etc. turned off. My understanding is that ppe supplies the handheld with tuning in it to flash the ecm alloying it to run as a stand alone rather than actually flashing the ecm for you.

That would make a lot of sense, especially after what I read about the no run issue with the duramax boat I mentioned earlier. It would be awesome if it turned out to be this simple. In my experience, usually the things that stump you are most often the things you weren't aware of or just plain overlooked, and this would be a perfect example.

 

[dslhtrdr]

Well, I just ran down to the shop and hooked up the tuner and loaded a tune into the Duramax, and nothing. Then I found the "Remove Security" function in the tuner, and still nothing. Loaded a different tune, and nothing. I'm wondering if the "Remove Security" did anything, because when I hit "Yes", checked the current tuning, then went to remove the programmer, it said no changes were made. I tried it 3 times, all with the same result.

I grabbed our Solus Pro and wasn't able to do much. Cleared the massive amount of codes it had (since it thinks it was hooked up to truck, and not a stand alone in a '67 Camaro) and it still wouldn't fire. There was no security relearn or ability to disable the security function with the Solus Pro.

Guess I'll post some pics to show what I've been up to...

My method of deleting the fuel test port and keeping the injector return line.

My intercooler.

Some shots of the wiring. The first is the mojority of the standalone harness for the Duramax. The second is the car harness.
