Well, I've been letting my lumbar fuse for the past two months so now I'm back into it. After lots more farting around I came up with, using the wise advice of a good friend, a distributor problem. A new drive gear and proper shimming to .013" end play I now have and engine that starts and sounds good - for 5 to 10 seconds then it dies. That is with the timing lead disconnected that goes to the ECM. When that lead is reconnected the engine will run longer but still dies after a few minutes. Watching the timing light reveals that the ignition is shutting down to cause the death. I monitored the battery voltage at the distributor and it stays hot during the death. All components in the distributor are new including cap. Fuel pressure holds fine during those few seconds when all is well. Any ideas are welcome. ECM?
