I drive a 1996 GMC 2500, I started it the other day, drove maybe 1/4 mile before the truck died and has not started since. I tested it with the OBD II and I got four trouble codes p0102, p0134, p0140, p0154. p0102= mass or volume circuit low p0134= o2 sensor circuit no activity detected bank 1 sensor 1 p0140= o2 sensor circuit no activity detected bank 1 sensor 2 p0154= o2 sensor circuit no activity detected bank 2 sensor 1
My question being would any of those trouble codes stop my truck from starting, because alot of people are telling me the truck should still run with those problems, and that the problem is something completly different. I have fuel and spark, so Im completly lost.Any one have any ideas for me.. please help. thanks much.

Try to drop the exhaust and see if it starts. If you sure that you have the CORRECT fuel pressure. First unplug the Mas Air Flow meter and see if it will start
