Hi I just replaced the head and installed a set of Tomei cams and my car will not start, I had to use a neo crank angle sensor due to the key way on the cam but i managed to rig up the old sensor with the new key way with the same results. All my Timing marks line up 100 percent on the crank and 2 cams and i have replaced plugs checked for fuel and even tried a timing light while cranking. I have a emanage computer which tells me that the car while trying to start is sitting on 172rpm and timing is at 18 degress. I have pulled the plugs out and have seen the plugs firing and also seen fuel going into the bore. I did have a fuse blow while the wiring was changed for the crank angle sensor but that has since been replaced i have also gone through my car with the muilti meter and have not found any other blown fuses. I am using standard cam gears not aftermarket so they can only be installed one way. Anyones help would be greatly appreciated The car will not even try to start it only turns over and over .....whilst getting fuel and spark....

I am currently waiting on the nissan consult software and cable to verify timing but the location of the sensor was exactly in the same position. also adjusting didnt seem to do much either i am currently waiting on another cas

Cranking revs seem a bit low (300 would be better), and RBs seem to like LOTS of timing (around 45 deg) to start.

Also, you have probably now flooded the engine. You need to crank with WOT until it fires.

My car always fired up when it was hitting 44 degrees timing, now it never starts first time when cold and only hits 25 degrees. Do you just use map tracer and see what cells are used during cranking and up them?

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
