So I have been trying to get an LS2 going into a 1970 Camaro. The issue is that it cranks, starts up and revs to about 1500 rpm, sputters, and then dies. Each start, it runs for less time until it just cranks. I think it is VATS. Fuel pressure was solid. If you give it any gas, the engine dies immediately. APP and ETCTP seem fine, they both respond to throttle input with engine off.
The details are as follows:
2006 LS2 (58X)
PSI Harness
2007 TBSS Throttle Body (silver blade)
2010 Camaro SS Accelerator Pedal Assembly
Bosch Green Top 42# Injectors (scaled for 4 bar)
Bypass style regulator set at 58 PSI
GM Service E38 Number: 12597121
GM OS: 12608677
GM T42 Controller
TM T42 OS: 24235341
I applied the patch, updated the VATS as such:
LABELS
Parameters Value
{G1204} VATS Enable Yes
{G1205} VATS Auto learn Enable Yes
{G1206} VATS Required To Run No
{G1208} VATS Fail Diagnostic Disabled
{G1209} VATS Mode No
{G1210} VATS Type Type 2
{G1211} Remote Start Allowed Yes
{G1214} Relearn Count 3.000000 Counts
{G1215} Relearn Timer 600.000000 Seconds
{G1216} Theft Relearn Password Yes
I also tried many combinations of No and Yes and Type without any change.
The starter relay was set like this:
LABELS
Parameters Value
{G1213} Clutch Depress To Crank Yes
{G1217} Maximum Cranking Time 15.000000 Seconds
{G1219} Starter Relay Diagnostic Disabled
{G1220} Starter Relay Type Not Used
What could it be??
Do I need to change any DTCs to Not Reported?
