hi all,
ive recently completed a new build and can't get the car to start.
Its a nissan 300zx with nismo 740cc injectors.
I can crank the car but it wont start.
One thing i noticed is that the green light on the ecu goes off and i loose connection to the ecu when i crank it.
The battery is new, i have plenty of fuel but i'm not sure i get spark if the ecu is resetting each time.
Any ideas ?

looks like i've managed to solve this myself thankfully.
After i sense checked all my connections and double checked the canbus cable short loom that connects to the ecu i discovered
that the wiring is all wrong compared to pictures i've seen online.
So i picked the cables off and put them in the proper locations and hey presto its working.
Just shows you you shouldn't trust ebay and double check the wiring connections when buying cables that are not oem.
