ECU talks to the laptop and controls/reads the sensors, but does not seem to see the VR signal and does not fire the injectors. nothing in the car changed since the car ran last time, could something have died in the ECU?

 

If you're not seeing a signal in logging there's a problem with that sensor or wiring for it. If you're not seeing RPM it's likely wiring or your Anti-Theft settings.

 

Antitheft! I haven't checked that. It's not wiring. The car ran before I attempted to load my tune to it.

 

I will give you more info to ponder. I had comm issues between the demon and the ecu. If you remember. I re-seated it and the car ran. The demon communicated and I then proceeded to load my "ok" tune onto it. That's when the car sputtered and died and will not restart.

 

It actually can be wiring if you're not seeing RPM during cranking but other sensors are showing live values. That or Anti-Theft.
