Default I datalog, you tell me whats wrong

First Up




Its a fresh start 355 out of 93 TA, lots of error codes

The engine was primed, then connected everything, had VATS disabled, and it will crank but no spark or fuel. Trying to get it to fire up for the first time

Thanks

LOL, it's going to take a lot more pictures than that, but your IAT does look way off.

you're in open loop and you're idling at 25 rpm?

with that many errors are you sure the preferences are set for a 93?

The engine looks not even to be running.

For the OP- a snapshot of the log doesn't really help much. Something is in error in the logging for you to have that many items showing up.

Green means good. If you were throwing DTCs, the cells would be red. In short, you're not setting ANY codes.

well if it won't fire a datalog won't say much then except that your car isn't running just like you probably figured out on your own

check plug wire connections to opti, valve lash, cam position, opti install, all main grounds, connection to coil, etc

It's kind of hard to data log without the engine running lol! first thing would be to check fuel pressure and spark.

You are better off actually telling us what is happening when you try to start the motor. Screenshots won't help whatsoever.
