ok so i had the catalytic converter blow off the turbo a couple days ago and i was lookin at it last night but the car has been running and all since then. so today i went to start it to move it up on ramps and it wouldnt start.

it cranked and cranked, but wouldnt fire up.

now, the only thing ive done since its ran last was unbolt one of the hangars for the exhaust down by the flex pipe and bolted it back on.

do you think maybe it has something to do with the sensors on the cat?
