Whats a valet mode? and how do I check it on my zr1? And your friend Mustang turned off when you guys are flooring it? Or it just stays there on 2,250 rpm and doesn't turn off?

Sooooo all this because you wanna do burnouts pretty bad?? I like how you think!

J/K of course but lemme get this straight...you purchased a non running C6ZR1...I can only assume sight unseen and imported it to a part of the world that *it seems isnt exactly brimming with LS specialists or tuners? You...my friend have huge ***** or a huge bank account.
It sounds to me like the car may have been a bolt on/ pulley/ tune car and had a few of the parts swapped back before you took possession. Of cours im making an assumption here but this would mean that even if the car were running it would need a new tune and a good once over at a minimum. I'd start by finding the most competent guy in your area to take a look and get back to us.
Of course I could be totally wrong and it could be as simple as the MAF is dirty but you wont know until you find someone who at least knows the basics.

Have you tried contacting David Steck at DSX to explain your situation and issue? He might have additional insight based on what's there or not there since it's his part.

What your assuming is right! I think the same. They took out almost everything that the car had. I have car fax and everything. But I just wish to know who the previous owner was. I found the car without x pipe, with this nr of V-belt Gates K120842HD So I assume that the car had a smaller pulley. I had to buy another V-belt because it has the stock pulley. Got the car without fuel lines + vacuum lines. it's got a crank pulley. without air intake box and the MAF sensor (Bought the MAF sensor NEW at GM) So it's been allot missing but manage to buy everything back and new. Yes i'm planning to bring a tuner out of the US to see if it's tuning I need That's why i want to gather information first than I can go for the next step.

The descriptions of the codes all seem to point to the intake area. I would be betting on a bad ground or a blown fuse...

Good plan, he is a really smart guy and REALLY knows his stuff and his products! And for that fact, you can probably have an "off the record" discussion on who he sold that part to (assuming the previous owner bought it direct from him) but of course we wouldn't want to violate any Right to Privacy laws ;>D

Ok. I will check all my fuses and grounds again. Should I check the interior fuse box? Or the one outside?

Ok bro, Just mailed him. Will wait for the reply. Let's hope he can give me some answers.
Thx for the info man. Appreciate it.

Are the injectors stock? If they are to big it will kill the engine off idle too

I would start with anything that looks like was messed with either by the original owner or that you reinstalled with replacement parts. Do you have the service manuals for the car? While the schematics are a pain to follow, they are helpful.

I did not look at the injectors. The car idle normally. My prob is when i'm gonna floor it or give it a little gas it will turn off.

The only things that have been missing are parts, other wise than that fuseboxes out and in seems to be normal. The fusebox in the interior seems to don't have the fuse of the exhaust. The one that open and close it. Beside that I saw everything normal.

Hey Johnathan, the kinds of testing we're discussing requires more than a visual check; you need a multi-meter and need to establish a good ground base point (somewhere on the engine block is probably good) from which you can take resistance measurements to the negative side of the parts in question. Anything that that reads greater than a few tenths of an ohm should be considered suspect.

Seeing that you have several map faults and the car has been apart if you know the tune is correct double check your map sensors. It’s very easy to have them in the wrong spots.

Make sure you have this MAP sensor for your LS9 engine ... If not, it won't run
