What is the standing voltage not running?
Started trouble shooting alittle more today.
Started with fuel system as it was sitting for the whole season. But I was sure everything was drained before I started this whole "adventure". Cleaned the fuel line/rail and injectors. Made sure the pump was putting out fuel and correct pressure. <<good to go. Ohm'd out the injectors and verified 12volts to each plug when cranking engine. All good.
Next;
Worked my way to the CMP sensor.
When cranking the engine the CMP sensor is not puting down the required, 0.7 peak volts. As a matter of fact its not putting down any volts. Removed the sensor and it appears not to have any type of debree, cracks, or defects once so ever, looks fine. Okay....so I figure I would crank the engine and look down the hole inwhich the CMP sensor seats down into. From what I understand from the manual, it gets that .07 peak voltage from the Inlet camshaft when it revolves. Sends it back to the ECU, and contributes to completing the FI circuitry allowing the engine to start.
Well, we have problem, the camshaft, from what I can see down in the hole is not turning when the starter is engaged.
Something gave during that first 30 seconds of startup / idoling time. I'm hoping camchain. My luck, busted camshaft? I'm certain everything was seated appropriate durning reassembly.
Ohhh man... I'm starting to feel sick.
:down:
I recon we'll be digging into that head cover tonight after work.

This explains my 30 seconds of fame then nothing.
First off..... how does this happen? I recall the inlet shaft rolling off the bench, but I caught it with my foot and the impact was "minimal" at best. (the end "tap'd" the floor (not the gear end)). My foot saved a complete drop to the floor.
Some questions plz.
What are my options as far as camshaft replacement for improved performance. I've heard that an exhaust GENII shaft inplace of the intake is the ticket? Good or Bad? Can a GENII exhaust cam take the place of my broken intake cam and be mixed with my GENI exhaust cam? Other options?
Lastly, how in the h#ll does the head cover come out with the engine installed? Do I need to lower the engine?
I know....i know.... the "SEARCH" button works wonders.
Thanks in advance.

Wow, im sorry i didn't get back to you, that really suks about the cam.
I was going to tell you to check the cam sensor!
Af far a a Gen2 cam, i have never heard of this. The main thing with the cams, a second intake in the exhaust side, along with set of adjustable cam sprockets!

Np John.
Yeah.... We'll leave well enough alone and stick with the stock camshaft configuration. I knew it had something or another dealing with swapping out the intake and/or exhaust camshafts or vise versus.
I'm kinda leary of buying a used camshaft if their that easily brake-able.... we'll see.

Replacement cam should be ready by next week. I was able to find one locally that will come out of a 2006 w/ 13K on it.
Big thanks to GIXERHP for offering up an extra for a member in distress. You good people.
So here is the broke shaft exposed. Question still remains.... "How and why did it break?" ideas?

No Sir. I caught it with the arc of my foot prior to it hitting the floor. The end of the shaft did somewhat ping the concrete floor. I've researched that it don't take much to cause a "hairline" type fracture, but would of never guessed it would of cause this. I've read a thread where a guy dropped one on the floor and chip'd a ear of the cam. He ground it out with a dremel, smoothed it over really good and re-used it. My drop would'nt of compared no wheres near that type of impact.
It happened after the first 30 seconds or so during the initial start up after re-assembly. And it sounded AWESOME for that 30 second idle, then it just quit (for obvious reasons). You can see it broken lying in the head on the first pic above. I snapped off that pic when I took off the bridge cover of the cam. I'm at a loss of what could of caused it. Did I torque down its' bridge cover evenly and correctly? < I'm certain I did? Did a shim jump? Dunno.
I was hoping someone could put up some other theories so I could know what to look for or do something differently when I put the "new" shaft back in. I'd hate to repeat this whole experience again if I'm doing something wrong.
???
lease: I feel for you
Thanks GIXERHP for that... I would of just installed it and thought it was all good. I'll be sure to recheck clearance.
I hear ya Delbert. Just my luck. Welcome to my life's story.
You would of thought the mail man would of just left it at the gate. Oh well, act two of start up video tomorrow. This time I'll use the phone.
