2004 Crank time... HELP!!!!

I am having trouble with a 04', v6, manual tranny Tacoma with cranking. The dealer replaced a wiring harness to the fuel pump and fuel line under a recall.
Originally I was experiencing trouble with crank times ( 3-8 seconds, similar sound to a dead battery crank) when the under side of the truck was wet. The dealer fixed the problem, and it went away for about a month.
now the problems back....
Took the truck back to the dealer and the dealer called Toyota and the Tech's there said that a delayed start like that is "normal" (3-8 seconds) and did no actual work other than run the diag. and call Toyota.
Here is the write up from the dealer:
"checked fuel pressure - no bleed down engine
crank time is normal. 5x2 te v-6 engine only
has 1 signal on cam and crank shaft has to
turn double in order to put cam signal again.
called Toyota tech assistance, vehicle is
starting as designed."
I agree with cam having to align to complete the circuit and fire the engine, however I dont not agree that it should take 3-8 seconds to align the cams and fire.
The other thing that leads to believe that there is a problem is that the dealership said that clutch pedal position can be affecting the start. I know there is a switch on the pedal that has to make contact for the motor to start and I know that my foot is to the floor on starts. ( pedal not depressed, no movement of motor etc.)
My question is 3 fold....
Does anyone have this problem of a long start (does not always happen)?
Does anyone know what the problem is?
Is this long crank cycle normal for the V6?

Some 2003 2004 model year Tacoma (V6) vehicles may experience an intermittent
extended or hard engine cranking at startup. A revised engine wire harness and ground
point relocation is required to correct this condition.

Plumber546-
Thanks for the info. They replaced the harness, I know anythings possible, could the new harness be defective? Is there a specific wire/connection point that I can check on my own with the Fluke to verify a faulty wire?
you can pass along the Bul. [email protected]
Thanks
