Yesterday I tried to start my Z for the first time since I switch a n/a to tt engine...

 

The crank rotates, fuel is ok, coil pack sparks. but not a single explosion.

 

Then I remember I swap the cam position sensor because of connector difference (1995-1990)

 

I though maybe it is 180 degree off (the half shaft connecting on the cam)

making it spark after the blow of the suck squish bang blow

 

Can I play with the timming without damaging something when I start it???

Can I play with the timming while the engine runs???

 

Any other useful information on the timming???

 

Could it be something else???

if no spark have u checked the ptu ? bu might have something to do with the crank angle sensor change. Im sure someone alot more knowledgable will be along in a min lol

Maybe your right ive also change the ptu and was not sure witch side to connect it

 

ill try that right away

 

thanks karlosg

 

Oh and turned out the crank angle sensor cant be 180 deg. off 2 crank turn for 1 cam turn :smw:

if the arrow point on the ptu point towards the hood it's ok it was running right on the previous engine (n/a)

How can i be sure the injectors are working properly?

I presume you upgraded your NA ECU to a TT ECU as well ?

If not, then that's your problem...

yes i did... but i kept the n/a harness, I removed the boost selenoids and add a manual boost controller

is it definaltey getting fuel , ie fuel pump all ok , fuses to it etc ,

yes i removed the fuel filter tube and there was pressure, ive been told its probably the fuel injectors, how can i verified if they work...

wrong crank shaft for the ecu. ecu isnt reading the crank markings i presume you have the same crank shaft as when the car was an auto? I had this problem with a vauxhall carlton, i got an engine out of a cavalier same engine apart from being transverse in the cavalier or so i thought, put it in the carlton and it wouldnt start or fire, took engine out after hours of changing timing a tooth at a time, changed the crank to the carltons crank and it started straight away. Bet thats your problem, the markings may look the same but could be in slightly different position so as far as the ecu is concerend it thinks the timing is out. Nissan may be able to tell you if the cranks are different.
