ok i got a 91 rs camaro with a 3.1 v6 i bought it a few weeks ago and it ran fine idrove it around town and on the highway and didnt give me any problems untill i got low on fuel and it died the gauge said it still had gas in itso i finally got it running again and put gas in it as soon as i drove out of the lot when id hit the gas it would cut out i finally got it home and the next day it ran fine i drove it down the higway and it died once and fired right back up and worked fine the next morning i left and it died again and kept acting like it was out of gas would start for a few seconds and die but it has over half tank and some how managed to get it home again and now it wont stay runing for more than a minute and it running like total crap i changed the plugs which were fouled out pretty bad and tested the map sensor, ignition module, and the crank sensor is still hooked up, so i have no idea whats going on any suggestions???????????????

sounds like the fuel pump and sending unit are going out.

ok so i checked the codes and i got a code 12 and a code 33 any one know what they mean??

Code 33 - MAP Sensor - Check the vacuum hoses from the MAP Sensor.
Check the Electrical connections at the ECM. Replace MAP Sensor.

hopes this helps.

this problem seems common and most of the time like everyone says is the wonderful fuel pump, but I had a similar problem and it ended up being my ignition module, I know you said u tested it...but so did I, had 2 places test it and they said it was fine, I just replaced it for the heck of it, and walla!
