Hello, i just bought the above vehicle, the dealership put a new fuel pump on prior to me picking it up because the gas gauge was not working. Worked fine the first week. Now my check engine light is on, when they plugged it up at autozone they said it must be a fuse cause the machine wont work.. Also there is a blowing noise (like the AC is on) coming from the vents, when the ac is off, when i accelerate it stops for a minute, then picks back up and starts blowing again. Any ideas?

Thanks ~

 

first issue, check cig lighter fuse

second issue probably a vac leak in the hvac system
