Random Starting LT1

I have a
1992 LT1 that had a very random start problem. Fuel Pressure was Ok, Spark
to plugs was fine, no error codes were set in ECM. Once the car started it
ran fine. Finally took a #47 (12Volt) bulb and put it across the fuel
injector wires. Found that when the car was dead the lamp never lit at any
cylinder. But when it started I could see the ECM lighting the lamp. I
checked the grounds to the ECM all were fine. Finally ordered another ECM
from The Last Detail. Has been starting fine every time for the last 2
months. (Just a side note the problem got progressively worse from the
point the failure first occured.) Hope this help anyone with a similar
problem!
