Bought a s1 rb25det motor, and Yesterday, i was able to start it up with no problem. I let it idle for a good 10 min. Then turn it off because it was getting hot and their was  no fan to cool it down. After, that i decide to bleed my clutch, then after i was done(30 minute later) I try to start the car and it doesn't want to start. It just crank n crank. 

-Look at fuel level and it was kinda at E, so thought it was that. Went to the gas station and got 5 gallon of gas, and still doesn't start. 

-Test coil pack with another set outter the car with 1 spark plug in it, and i can see spark as I crank it.  

- Test injectors if it clicks, and yes it clicks wen I crack it. Loosen the clamps on the fuel line if I get fuel in and out and I do no problem. 

-cam angle sensor. Unplug and plug the sensor while it's on postive I can hear click click sound, so I believe its working correctly. I even took it off and rotate it by hand and it clicks every time I turn it. 

- timing belt. took off timing plate cover, then Rotate the motor to top dead center twice, and everything lines up on the dot. 

Compression, spark, and fuel all check. What else can it be beside what I mention?
