LT-1 issue

[John Nechiporchik]

Alan, Thanks for the info. I'll pull the fuel pump as soon as I finish my analysis on the Optispark question (below)
I tested the TPS with the following results:
Per the Accel manual, the input signal is 5V.

Input signal was 3.32 Volts (issue??)
.48 Volts at idle
1.74 at mid throttle
2.67 volts at WOT.

I tested a spare throttle body /TPS and got almost identical results.

Dyno/Lee: On the last pass I made last year, I destroyed the stock style rotor.It literally shattered in the shutdown area.
Over the winter, I replaced the cap and rotor with MSD parts.
Is it possible that the catastrophic failure caused some damage to the distributor itself that is resulting in this condition? All input appreciated.
