Well, we finally think we found it.

When this all occurred, we purchased a Russell ?6an one-way check valve and placed it right before the rail, to rule out the internal check valves of the three...

Respectfully; The car starts and runs, it just shuts off after a few seconds

So rail pressure is at about 60 psi during cranking. I?ve even forced the pump on through the VCM scanner and it?s the same result. I guess some thing I?ve never considered, though was actual fuel...

No, that?s the issue. The car dies, the key stays in the on position, so he cranks the engine over again, but then the car starts and dies. It does not idle for more than just a couple of seconds.

Ok. I got my brother to send me the log using my laptop. I can?t see the log info since I?m typing this from my phone. If I can get my laptop from him soon, then I will try to take a peek myself. But...

Thanks for the latest reply’s.

One person asked about throttling to keep it on, that does nothing. No matter what input.

I’ll get another log going.

And I don’t necessarily think...

I’ll take a step forward since I’m just looking to get the car fixed and apologize for my confusion.

Im passed the basic checks and I feel like this is well beyond some basic air/fuel/supply...

Everywhere I?ve read (emphasize my research) has said full write for OS and VATS changes.

If you don?t wish to help, that?s ok. I?m looking for input or guidance through dialogue from people who...

Thank you, all for the replies. I?m hoping my experience can help someone, no matter how much of a pain it is for me.

We have verified fuel pressure, 58 psi base. We have even bypassed the factory...

Thank you for the reply. I?ll give it a shot.

Looking back at old tunes, that?s how I had it set up, but somehow it?s off now.

Hi Guys,

After so much time spent trying to find this on my own, I'm out of ideas. I don't like to post on any forum until I've exhausted everything in my knowledge.

Long. and short, we were...

it turns out the injector data on my thumb drive was for 1400cc inj not 1000c. I adjusted the IFR, and it runs!

Installed this tune above, with high and low MAF failure @0, same result. Attached is the log120061

Are you suggesting I install this? I see the change to low FREQ MAF, is that what I missed when I set mine up?

I will add, I had codes P0120, P0220, P1516 prior with the last two TB's. Even with the harness having tps 1/2 swapped, and 5v/ground swapped.

The newest TB throws the same codes, until I swap...

Hi all,

To say this has been frustrating is a huge understatement. I'm working on my brothers 2004 Corvette Z06. The car has an A&A SC kit, and we were looking to go e85. So while installing...

you dont have it hooked up to tune?
