Good Afternoon,
94 LT1 (no emission, computer reprogrammed), installed in 65 c10. Been running for some time, not yet driven. Check engine light and mis-fire. Cannot get code reader to read.

Removed, tested and cleaned all injectors, reinstalled, now, only turns over, won't fire up.
Fuel pressure is good, power at the injectors.

any ideas?

Any spark?

As nailhead said, check spark. You have OBD 1 so it will be hard to find someone who can read it.

I have same engine in my jag and only thing I can advise is to Get yourself a cable and download scan9495, you can not only pull codes, but you can also scan and monitor everything going on! I believe the author of it might be a member here! His name is Garydoug!
I use it to create data logs as well!

I was mistaken, he’s not a member here that I can see, he hangs out on ls1lt1.com

1st spark if not then check to see if there is any power going to the distributor if none keep looking on down up the line. if there is check timing.

I would have to listen to it and then maybe put a finger on the exact problem
