M30B35 NA Crank no start

[Ohnoitsirshad]

We just rebuilt the engine, we had this ECU profile even before the rebuild, but after the rebuild it doesn't start.

The only difference from pre-rebuild and post-rebuilt is the Cam sensor cover.

Currently on MRT Engineering M30 Cam sensor plate. Previously was a makeshift but was as close to the position it is now.

Attached is the Profile, Trigger scope and data log.

The trigger looks fine, what makes you think there is a trigger issue?  

The first thing I would suggest is to take notice of the red fault codes at the top of your screen.  The "AN Volt 2 below error value", is likely what is preventing your engine from running.  This is your MAP sensor input, so your MAP sensor is not connected, connected wrong, or not working so you are getting no fuel injected. 

It also looks like something is wrong with the TPS wiring, the AN Volt 1 voltage drops when cranking and is very noisy.

Just thinking it could be human error when installing parts, but all is good for trigger now.
