SR20 has spark, fuel, no start

[greenman100]

The engine cranks and cranks, and will occasionally make a loud POP sound, like a backfire, but the engine never catches.

I have spark, at least on the number one cylinder. I have fuel pressure, and when I rotate the CAS, I can hear the injectors clicking.

I had to replace the 7.5A EGI Fuse in the underhood compartment.

The gas in the tank is about 4 months old.

I've replaced:

Spark plugs
Coilpacks and subharness
Ignitor

It still won't idle, just makes the backfire sounds. I've checked the timing, including the CAS, compression is around 130.

Ideas?

Where is the fuse for the start signal?

The "loud pop" is probably you trying to crank numerous of time and dumping fuel into the motor. Double check spark maybe a coil pack is bad or something

When it pops, a puff of smoke comes out of the exhaust.

I've checked, spark is good. Can the gas go bad in 4 months?

CAS was set 180 degrees off, on TDC exhaust stroke. Swapped it to TDC compression, problem solved.
