I've building this car for some time, it's mostly stock other than long tubes, ported TB and CAI.

The tune I have is also mostly stock, other than things like delete rear 02s for headers, I'm...

Latest start attempt log with replacement TAC module. I'm also logging 0.00 volts at the TPS, can someone tell me if that is normally zero until it starts or should that also be at 5 volts?

No go on the Tac module same just cranks no start.

Running out of sensors to try:) I guess I can throw a TPS sensor next?

I did buy a cheap Crank Sensor at first and ended up getting an ACDelco just in case, same for the CMP. I have RPM on the scanner which I'm told tells me the sensor should be good. Granted it's...

I hear ya, I actually pulled injectors and ran a pulse to them and they do spray. Figuring they're cheap enough I tried a set of new injectors since these had been sitting for some time, still a...

The TAC module does run the TAC motor and it moves consistent with the pedal. The TPS 5volts also comes from the TAC module, right now that's the only thing I can find missing is 5volts on PIN F.

You're talking about these right?

P0101-103 was set to Mil on first error.

I added a couple more channels and the recommendations you made, still a no go. I did notice that TPS reads 0.00V I'm assuming that needs a voltage while cranking?

I have 5 Volts...

Added bank 2 logging with a few other channels, another start attempt

All the Corvette wiring harness are all there and not modified. I'm actually leaning on thinking the PCM could be bad...

Have tried with spray and plugs get fuel on them, half tank of gas, plenty of fuel pressure too.

Also tried new Starter Relay and swapping relays in the under hood fuse box.

Here's a new log with that MAF reconnected and brake booster.

During that attempt I did have the MAF/IAT unplugged but the symptoms are the same with them plugged in. I'll look at the MAP sensor.

I've been working on this on and off for a few years now. The swap is all 2002 C5 PCM, TAC, BCM, Drivetrain all factory harness and fuse blocks.

I've had it running but never driven on the street,...

Cranks hard but no sputter.

Checked has pulse via, noid

11.8 vs 12.2
Vats is already disabled

Does anyone no where this value comes from, I'm chasing down a no start problem and mine reads 11.8v. I also noticed Fuel System Status = "OL-Not Ready"?

Car cranks, has 50+PSI at the rail and...

I popped off the fuel rail cover and found the evap purge valve line open which I had forgotten about, in the one pictured I think the other end runs out to the canister? I'll have to run a...

MAF is clean, no air leaks, no exhaust leaks, pulled plug 8, looked a little rich but ok and not broken. I did find an open vacuum fitting that I plugged for now.

It does look like LTFT's are at...

2002 Corvette LS1, only mods are CAI, ported TB, long tube headers, no cats.

Only driven in the driveway since swap.50512

I'm getting a lot of misfire errors and backfire through exhaust, any...

same question, does it need to disabled?

In my case I was swapping laptops and the new one with vista hadn't worked yet so drivers were an issue for me since I didn't download them with the new beta s/w.

You were right though something...
