Re: Lt1 no start help me!!?!?

My batt. Was too dead to try so I reaaly only got to check for no1 and 3
No. 1 seemed to rotate probably like 4-6 full rotations of the harmonic balancer between sparks. No3 seemed to be a whole lot closer toger about ever spin or two. Then the battery died. I have a timing light I put on it I really only have pulled the wire off no1 and put the spark tester from autozone on it but I have a really strong spark. Jumps easily about 30 on it( around a inch inch and 1/4

This is for a 1996 Z28, but most of it should apply for the '95(any DTC references may be wrong...as it's OBDII). It may help out on what is wrong.

It does sound like there is some kind of timing/opti issue.

Sounds like a rotor problem to me....maybe pull the cover off the opti and see if it's still intact.
