HELP!! Belt exploded and ate my MAF now won't run no DTC's! At the track and the belt jumped grabbed my maf harness and tore it to ****. I though the car would run without the maf, but it's acting like it's not getting spark or fuel just cranking away. I have my laptop there with HP tuners and most of the DTC's are set to show light and DTC on 2nd. It's not pulling any codes. Any ideas? I was trying to think what wires are near the belt that it could grab and mess with. Oh and my car is still sitting an hour away at the track!

It torched your maf harness? like you had it unplugged from the maf (that's how I do it when I SD tune)?
Try separating the wires to make sure your reference voltage isn't shorting across the sensor output wires...

Check out the reference voltage (PCM +5V) that goes
to the MAF and see if it's up. A short might have taken
out the source driver, or just a PCM fuse. Presumably
the fuses are checked already, or OK since HPTuners is
still communicating with it? If the +5 goes down, a lot
of sensors are dead meat.

Is the ref voltage a PID in scanner? Tell me more about the +5! Is it a fuse or something to check in hptuners?
