What's your fuel pressure reading after cranking?

This. If you even remotely suspect the fuel pump isn't getting pressure (verified through a gauge), swap the relay next to it (AC relay). I had a relay take a dump overnight one time... one day it was OK... the next day, nada.

Does the tach jump when you crank it over?

I am now having this problem also what does it mean if the tach does or doesn't jump during cranking.
My symptoms are nearly identical. After rebuild it ran with old programming but was very rich at 8-9 A/FR but would idle, got a new chip and it would run at 1850 or higher anything less it would stall. During T/S of why it wouldn't idle right it now just cranks with an occasional hint of firing over, misted fuel into T-body with no success of it trying to start . Plugs are dry have spark, new ICM and IAC, no damaged wires plenty of fuel, intercooler is disconnected from turbo so engine is effectively N/A right now. Timing is off but it was running got it set at 8* BTDC I know it needs to be 0* BTDC

everything worked as needed and after getting some fresh heads(minds) on it, the problem surfaced BAD PLUGS even though they had what appeared to be a strong spark.
Thanks Turbo7521 for your input. Sy #2811 now runs and idles fine now just need to dial in the tuning
