Day 2 post cam install, and it still won't start... Everyones ideas have been exhausted and it's my daily driver. I'm beyond sick. There is just nothing showing up to be the culprit and it's pissing me off. I've taken a personal day off today I'm so sick with stress and disgust. Here is the thread I've been working with thus far on LS1.COM for some background:

Anyone a mechanic or know one that travels and works for peanuts? This project has left me broke both financially and emotionally...

try pulling out the cam position sensor...you might've bumped it during the cam install which will make it inoperative.

thats not right..
there is only one Dot-to-Dot.
the crank position sensor above the starter motor didnt get unplugged did it?
any other sensors get unplugged ?
check all of them thoroughly and also check the three ground wires at the back of the drivers cyl head.
got fuel?
does the motor turn over even?
lets get some specifics on this so we can work on getting it running for you.

I was there installing the cam, so here is what happened. The dot on the cam gear was facing 6o'clock, we took it off, took the stock cam out, put the T1 cam in, when finished, the dot was facing 6 o'clock as well. So how could the timing be off any??
Here is one hypothesis that I am coming up with. We had a hex wrench in the flywheel so the crank wouldnt turn when we took the pulley off, well for some unknown reason, this wrench was left in the flywheel after the starter was installed (the guy that said he took it out....didnt take it out) so when we first tried to start it, all you would hear was the starter turning... Now wouldnt this still shoot fuel in the cylinder?? once we found the problem, we took the starter back off, took out the wrench, and bolted everything back up...when he first tried to start it again, we heard a loud "POP". I am guessing that was the excess fuel in the cylinder. Now it just turns over. Would the plugs be fouled now? He takes the plugs out, they are wet, once dried, he puts them back in, turns it over some more, takes the plugs back out to find they are wet.

ok lest start here.
on the fuel rail, drivers side there is a cap on the front end. take the cap off and you will see a sharder valve, kinda like what you have on the tire/wheels on the car.
push in on that little rod/pintle whith the ignition on. fuel should exit th rail at a high pressure. so be carefull and have a rag handy.
if you got fuel at a high pressure, like 60 psi or so, your fuel is fine.
second....
about the cam and crank dots.
you had the cam gear at the six oclock position right?
that means you should have the crank sprocket at the 12 oclock position.
hence the term dot to dot.
also, check that crank position sensor on top of the starter. is it still pluged in?

Side question for Steve or anyone else.. I've always wondered, does anyone know which sensor is specifically used for what as far as crank and cam sensors go? Is it the cam sensor that's used for ignition timing?

Assuming you have air, spark, and fuel, it has to be a sensor problem.
Taking some shots in the dark here...
Make sure you didnt shear the teeth off the starter gear when the flywheel was jammed....
Make sure both coil pack harness are plugged in...
Check all engine grounds...
Check all relays...

The coil pack harnesses seem to be secure and good.
All the grounds I could see were in place, tight and clean.
All the fuses (two locations under hood and one inside cabin) look good and I did actually swap out some of the relays (the fan in place of the ign etc) to insure that they were fine as well.

The next thing I would do is put the engine at TDC by putting your finger across the #1 cylinder spark plug hole (after taking out the plug, of course) then pull the valve cover and be SURE the intake and exhaust rockers are completely up and not moving (indicating the valves are closed). If the intake or exhaust rockers are moving AT ALL when the cylinder is coming to TDC, then you've got the cam phased wrong.
Just checking the possibility that you may not have had #1 TDC when you did the swap.
