New engine in pontiac fiero will not start ***Fixed

Hi I am new to the forum..so if I miss some information that is needed to diagnose the problem just ask me for it. On to the problem...

I have a 1986 Pontiac Fiero with at 2.5 4cyl. I blew the piston rings in the engine sometime in late september. I bought a rebuilt engine for it and took the last few months for me to put it in. I finally finished all the little details and tried to start it. The engine turns over just fine, there is spark, oil pressure and compression. The fuel injector is not spraying any fuel, but that is another problem I think I can fix. I was just trying to get the engine to start so I put a little gas in the intake. All it did was backfire a couple of times. I am pretty sure this is a timing issue, but I don't exactly know how to proceed with fixing it. If you don't know the 4 cyl has a set of timing gears that once the engine is put together can not be seen or adjusted. The timing is completly electronic, and it does have a distributor. If someone could just point me in the right direction on where to start adjusting, it would be appreciated

Thanks
