its not turning over, unless i hot wire the starter or pull fuse 23 out. the starter only tries to turn over the motor momentarily then it quits. when i try to start it normally i know there is fuel because when you press the valve on the rail it sprays out. i know there is spark too because i can have a wire unplugged and see the spark arcing out.
yea that would be my theory's also. try the clutch switch, and any grounds or wires leading to the starter. but from your discription. it sounds as if the car isnt getting juice " thus a wire loose or something.
When I installed my motor, I had to reference this....

That is from WS6.Jay's post on Corvette Forum. I didn't say you'd replaced the T/A's clutch I meant you had replaced the C5's clutch and that the symptoms were similar. Sorry your car is still not running.

Have you checked your ignition circuit ? Also have you checked for codes ?

It's about a $10 part at GM. You can make a jumper to see if your car turns over correctly.
I have the 3 book service manual for a 2001 corvette, what year is yours ?

Have you checked to make sure that you are getting constant power while cranking with a electrical light tester.
Have you checked the starter to see that it is not binding ?
I would recommend putting a check list together of what you have done and tried so that we are not all spinning are wheels here.

it almost sounds to me like the clutch switch is faulty, providiing just enough continuity for a momentary contact, but then petering out.
have you tried bypassing the switch with a jumper wire?
