LM7 stage 2 cam tune help

[AtlasAuto256]

I own a restoration and custom build shop. I am new to tuning and i am having trouble getting this LS swapped 1987 monte carlo running again. My tuning guy has left me high and dry and now i am trying to figure it out myself. I had it running enough to drive it around the block but now with that same tune it will not run. I have changed the tune and made adjustments based off of another LS swapped truck i have with a stage 3 cam. That truck runs decent enough to drive it around but i still cant get this monte carlo to run like it did before. I have attached the 1st tune that had it running and the 2nd tune that i have done. They are labeled 1st and 2nd tune. Any help would be greatly appreciated. This is a rebuilt 2005 LM7 5.3 bored 30 over with a sloppy stage 2 cam, cold air intake, stock torque converter and long tube headers.

No mention of checks outside of tune. What does “not run” mean?

Need a log also.

Might be worth it to post log file so we can check to see if anything is wrong first.

What did you do to develop this VE table? It is not good. It looks like a lot of random tables were copied from a vehicle that might have had an ETC throttle body and this one has a cable throttle body.

It tries to start but will not start. if i keep trying it will start up for a second and run rough and cut off. i am by no means a tuner. i had a guy that was working for me that did all of my tuning. but he quit. i will post a log file of it trying to start.

This is the log when it wouldnt start

Going to need to know what the fuel pressure is doing.
Thats rule #1 on a LS swap. Never assume its good.

[AtlasAuto256]

Fuel pressure is at 55psi while cranking. That is with a mechanical fuel pressure gauge, not a sensor.

2XLS1 That was from another LS swap that i have. and yes it does have an etc throttle body. i was just trying to play with the tune to get it to start. i am now using the 1st tune file

See if it will run on flammable parts cleaner or starting fluid.

[AtlasAuto256]

It does not start with starting fluid.

You have a spark issue then.
Are you able to see any rpms on the scanner while cranking?

PCM needs to see crank and cam sensor data synced before it will fire a plug.

I the log it looks like it's trying to run. Need to pull the plugs and make sure they aren't fuel fouled.

Need to treat it like any other no start that comes in the door. Check all your basics first.

i was able to get it started this morning but i had to keep pumping the gas to get it to start and to keep it running.

did you have the canner hooked up and saved the file?
if you do post it so we can see what it is doing
---or hook up the scanner, turn ign on, start recording on the scanner and then start the engine.
when it dies, save the file.

this way we can see what you see...
