ep3 cranks but won't start?! help!
Hey guys so I bought an 02 ep3 Si and the previous owner said he believed it needed a new motor. He claimed to be driving normal and the car just bogged down on him and wouldn't start again, he initially thought he ran out of gas. The car has what I believe to be the original k20a3 (can't find the block code lol), as well as I/H/E and kpro.
Fast forward to now, the car has gas in it and will crank but will not start. When I crank it at first it sounds normal then seems like it's starts cranking faster almost like there is no resistance. I don't hear any knocking or odd sounds coming from the motor so I'm not convinced that it's blown.
I have the fuel pump priming and I have fuel at the rail as well as voltage to each injector with the key in the on position.
I would like to check the coil packs to see if they are in spec with my multimeter but I'm not sure how or what ohms they should be putting out?
I am also waiting for someone to come help me crank the car while I use a screwdriver to check for spark, unless there is another way to check for this?
I would like to check off the obvious before i go any further, and by that I mean fuel/air/spark. How do I make sure air is getting in? Please help if you have any ideas, thanks!

Update: car seems to be getting NO SPARK in all four cylinders. I checked with a screwdriver (the only way I know how)
What could cause the car to not fire on any cylinder? I dont think it's the immobilizer bc the green key flashes a couple times when you put the key in the on position but then goes away. Also where are the oem grounds supposed to be on a stock si?

Check mechanical timing, they are known to stretch the chain and skip then bend valves, a simple compression test will let you know, as far as spark goes pull the coil stick a plug in the end of it and have someone crank the car and watch for spark while putting the plug near something metal.
