Staring problems
On my 94 LT1 auto yesterday morning I went to start it and it started but it ran like something was unplugged, thrown a code for about ten seconds, then ran fine like nothing happened. Then this morning it did the same thing but it diesel out. Then started back up and ran the same way but longer. Also both times the amp gauge was reading about 14.5- 15 volts. And when I drove it to work yesterday it ran the whole way 7 miles at 15 volts. So today I did not drive it to work. And when I can home I started it and it fired right up and ran fine and was reading 14.5 volts. My dad thinks there might be moisture in the fuel injectors doing start up. Its been in the low 30 mid 20’s doing the night and it does sit outside. Also this weekend I am taking it to someone with a scanner to try and pull a code since the light came on.

Since it's gotten pretty cold here, my 92 has been starting right up and if it doesn't warm up enough will die when starting to move. I haven't looked into it and never throws a code. Could be something due to the difference in temperatures.

Same thing here. We had a week of cold mornings (30-35*) and I had the same exact symptons. It's warmed up about 10* and everything is fine.

Even the AutoXray scan-tool can take snapshots.
With graphing software, you can sit in front of your computer and analyze the graph of the snapshot parameters and see exactly what happened -- no guessing involved.

update. I pluged in a snap on scaner, and it pulled up one code. it was for the coolent senser on the water pump. the only problem that was a brand new from GM when I bought the car in aug. so even know I knew that was new, I went out another one from GM. I put it on and reset the computer. so now I have to wait and see if it does it again.
