2004 8.3 V10 not cold starting
You guys are my only hope!
Specs; 2004 Viper 8.3L V10, Drag pac harness with '04 ECM with race tune done by Arrow Racing.
I can start it with ether, it takes a bit of fighting but it will go.. I have 58 lbs of fuel at the rail.
Once it's running, it idles smooth, great throttle response.
On the harness I have a wire Z12, which is apparently the injector ground for the ECM loop, regardless if it is hooked up or not, it still will not start.
Any info you require to figure this headache out I will gladly supply.
