Default replaced oil pump, now won't start

2002 WRX Wagon, 5sp, 130k miles:

I had to replace the oil pump, and now it won't start. It turns over. A couple of times it sputtered like it was going to start, but nothing. I over filled it with oil (Maybe 2 quarts?), but I have drained out the extra. I triple checked the timing marks when I put the belt on, and before I put the covers on.

And before someone asks, it has gas.

I have no idea at this point. Anybody?

Not an expert, but I've read enough to tell you "Sounds like a timing" issue.

Did you make sure you "Wound" up the cam sprockets when you put the belt on? I did my belt a little different, so I wouldn't have to reset the cams. Might want to double check it.

I don't see why overfilling it would cause any problems. I think the problem lies in timing.

Just my $.02

I read in another thread that if you are missing a tooth on the crank sprocket, it won't start - and it just so happens that I think I broke one tooth off. I am going to try replacing that ($15 part) and see what happens.

I was being dumb (go figure), and I used a pry bar to get the gear off. I pried in just the right way that it bent the tooth a little, and when I tried to bend it back, it snapped right off.

Just in case there is any confusion, I am talking about the little teeth around the outside for the crank angle sensor.

That can do it if you broke one of the teeth.

Since now your crank sensor isn't seeing all the teeth, it won't start. The sputtering start-up is probably the ECU picking up some of the signal, but then dropping since the signal is missing momentarily. Thus, you never have a complete start up.

When you replace it, recheck your timing belt marks.
