EJ25d backfiring after reseal. gaaahhh

The crank snout was so screwed up, we ruined the tone ring on the sprocket getting it off. A friend had a brand new one he bought for a 01 RS, so we used that.
We just put everything together, and went to start it up, and it cranks a few times, catches, then backfires through the intake, puff of exhaust out of the airbox and everything.
I'm 99.9% sure we got the timing right with the new belt. Everything appears to be hooked up. Any ideas? is there a chance that the tone ring on this sprocket is slightly different?

tried unplugging the crank sensor, no change....

You used the dot on the back of the sprocket for timing right? Not the arrow on the front.
Cams could be out as well. Are you sure you put the sprockets back on the correct cams?

yep, used the correct marks. but we're double checking now

timing was off. reassembling now

COuld the spark plug wires be backwards?
We checked that...
It was the timing belt. Must have lined up without the slack taken up or something. All 4 cams in sync with each other, one tooth off at the crank sprocket.
After a little shenanigans to get the coolant system bled....it runs great. Was supposed to be a fix n flip.....might keep it....

Yeah, go for it. It always seems the one you sold is the one you should have kept. Good luck with the rest of it.
