Check the wire leads and clean them before reconnecting the wire leads. It wouldn't hurt also to clean the MAF sensor with MAF cleaner, the code your getting is most common to the high performance oil base filters like K&N.
Good luck and this should help you resolve your MAF issues. Thank you for using Fixya

SOURCE: 1999 Chevy tahoe will not start
check the crank sensor. no signal from the crank sensor causes a no spark condition. best way to check is to put a scanner on and check for rpms.
the crank sensor is differnt from the cam sensor

Basically this means that there is a problem with the Mass Air Flow (MAF) sensor or circuit. The PCM detects that the actual MAF sensor frequency signal is not within a predetermined range of the calculated MAF value for more than 4.0 seconds. I would try cleaning out your MAF sensor with some carb cleaner and reseting the check engine light to see if it comes back on. If it does, get back on here and let us know and we will walk you through some other things you can try. Cleaning it out will be the easiest/cheapest thing for you to try right now. Good luck. Thanks for an honest rating and for using FixYa.

The MAF (Mass Air Flow) sensor is a very common problem with these along with the pickups. This isn't what you would call an inexpensive part. Definitely do some shopping before you buy one.

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.
