HELP!! Spark problem and gas leak!

I recently swapped my engine with a newer 99 engine into my 98 impreza. I have everything hooked up (or so i think) and when i go to start it it won't completely fire up. Checked my spark plugs and i get one initial spark and after that i get nothing. Same with all four plugs. I also have a gas leak coming from my driver side header, which i believe is because my plug isn't igniting the gas coming from my injector, leaving the gas siting in the combustion chamber and eventually leaking out.. correct me if i am wrong. I am baffled! Yes, my cam and crank sensors are hooked up, and yes my coil is good, it was running the day before i swapped on my old block. HELP! I do NOT want to bring it to a garage and pay useless labor costs when i know my way around the car!

Sounds like you got phases mixed up, need more info.  99 2.2 or 2.5?  sohc or dohc.. etc

Yeah i do have a phase two block but that was the point of putting the engine in. I used my 98 phase one heads and intake. Took the 99 phase two block with 60 k miles on it (compared to my oil leaking 212k phase one). The blocks are literally the same, both are SOHC and 2.2 liter. It should work perfectly fine but my spark plugs aren't working correctly. I had my motor out again and still couldn't figure it out. Anyone else had a problem like this?

Just changed my crank gear and also my crank position sensor. Now i am not getting any spark at all. I am thinking i may have ruined the sensor i had to jam it in pretty hard and its not all the way in. How close does the sensor have to be to get a reading? Anyone?

I'm not hugely familiar with that sensor but it might have to be seated fully. Although I would think you'd get a check engine light if the sensor wasn't reading right.

If there is an issue with the crank sensor you probably won't get a code at all. It does need to be seated fully.

It gets very close to the teeth on the crank gear.  Random image off google

The sensor is pretty delicate too.
