I was back in the garage working on the talon and after replacing cps, ckps, water temp my car still doesnt start. I am getting fuel. The spark only comes after about 5-10sec of cranking. I also have changed my asd/fuelpump relays and now I get codes 12(air flow), 41 (injector something), and 43 (egr fault). Can someone shed some light on this subject cause I cannot find anything thus far. Thanks
 
Forgot to put in there that I do have and egr delete. I was told where I went turbo that I am better off without it. So far my car hasnot run since the build. I have replace almost all the sensors and am going to be rechecking my voltage values tonight I was hoping someone would have some insight so I am not thinking of this while Im eating LOL
 
Compression Ill be checking tomorrow but they are new rings. As for the cam gears I double and triple checked before the engine was dropped in
 
Did you get another ECU and see if that works yet. I have seen plenty of 420a ecus go bad just by looking at them wrong. If you have a friend with a 420a just switch out the ecu and see if it fires up.
