I recently changed my fule pump to the racetronix pump. the car ran good after i put it in. when i was pulling up to my drive way the car cut out. then would not start at all. Once i disconnected the maf the car fired up. My car was throwing this code P0100. Does this mean i need a new maf or does this sound like something different?

 

PO100 MAF Sensor Circuit Insufficient Activity

I would try a MAF sensor. That's what it sounds like to me. Did one like that last week and it fixed the problem.

 

Im buying a new MAF today
