Hello all.

I need a little advise before i go a spend 2K on a new computer for my car.

I had a running g35 4 months ago when it was brought to the dealer.
I have since had the motor replaced and a greddy TT kit installed.

Currently I have no spark and no Injector pulse.
I do have signals from my crank & Cam sensors and signal going through to the ECU. But no signal out of the ECU to fire either the plugs or the injectors.
What could be the problem.
My shop is telling me it has to be the ECU either on ANTI Theift mode?
or the ECU is funked.
Anyone know how to reset the ANTI thieft? or any better ideas as to why there is no signals.
its all grounded and connected the right way just no spark or injector pulse.

 

Your best bet is to get on the my350z forums in the fi section for help on this problem.Are you using the greddy blue system that came with the kit or a different system.The greddy emanage blue is absolute junk and if it is wired wrong you will not get any injector pulse or ignition spark.

 

I am running the Utec and Tuner Wide band A/F All turo XS equipment.
However even when we use the stock ecu there is still no spark of injector pulse.

 

Same exact problem but I have only bolt ons not FI did you happen to figure it out by chance?

 

Mac was upside down.. Revive installed and fired right up

 

Computer was upside down? I don't get it

 

No the mass air sensor was upside down. We are using a mustang sensor. The readings would not allow the computer to fire the engine.
Once the maf was fixed the car ran. Still needed tuning. This is a very old post took a moment to clue in.

 

Lol actually this post is prior to pulling out the utec and using stock computer with osirs uprev. Utec is for low end power. My repair noted above is after the uprev install. Same problem was unidentified prior to shaping ecu systems.

 

I'm not getting any codes on my POS obd2 diagnostic readings and it won't start a few time it has started and died a few seconds later then nothing

 

I am running the Utec and Tuner Wide band A/F All turo XS equipment.

 

Tore it down the the almost to the block lol put it back together swapped coils and plugs around started every time but died flipped the mass air flow sensor worked perfect no idea what the problem was

 

MAF in backwards will not work - when installing make sure you use the air flow direction arrow. If installed backwards it will keep car from operating.

 

Right, you are correct but, before I had no spark and no fuel, not being caused by the MAF

 

If you have no spark or fuel try the ecu. Check for faults I have seen rain or wash water cause damage.
Just cranking the car will give fuel. Test for pressure at the fuel rail.

 

LMAO really brought this thread back from the dead
