Check inside the distributor cap. Make sure the spring loaded piece that makes contact with the rotor is still in place.

Forgive me Patrick, I don't think the LT1 has a distributor cap. Optispark?

Oops, sorry... I was just responding to the info in your post prior to mine. I forgot about the LT1 swap.

Do you have spark at any of the plugs?
str8maxn MAY 06, 07:31 PM
I've only checked one plug.. but the engine does not turnover . So, I am assuming none have spark.

Ill have to check ...

No Spark can be any number of things... best to work backwards at that point, could be anything from a bad ignition coil, to a bad ignition control module, to something else on the distributor like a bad pick-up coil or who knows what. I can't remember... did you say whether or not you had any computer codes?

Reminder it's an LT1 swap

Hello all,

A bit of troubleshooting yesterday. It looks like I do have spark. I was able to confirm this using a spark plug spark tool. Although, I think the spark was weak, but the battery was a bit low too.
I also have 40 PSI of fuel pressure. Not sure where to go from here.

Any advise would be appreciate.

Need clarification here. Does the engine not turn at all? Or it turns over but does not start?

I assume you don't have a service manual for an LT-1 Camaro/Firebird. Do a google search and download a service manual for the year of the engine. Then follow the troubleshooting chart available in the manual.

Edited to add: See example from 96 Service manual:
