Sorry for the confusion created. The car cranks but doesn’t start. Updates so far; I plugged a “Bluedriver” (Bluetooth obd scanner) it didn’t show DTC’s however it recognized a U1000 or communication error between system control modules. Now I’m worry it might be the ECU got messed up may be because of the battery (which was indeed bad because I took it to the auto parts to be scanned and got it replaced) and or perhaps after I try to jumped start the car since I’ve heard bad things happened to modern vehicles ECU if trying to jump start them. Still I went and got the battery replaced with a new one, installed the new battery and the obd scanner once again to erased the codes and try to start it again one more time but NO LUCK. Proceeded to remove the intake and plenum to replace the plugs and clean the throttles. Noticed I could smell gas on plugs after removed. Not saying these were flooded with gas but i could smell it and the plugs were moist. That said I believe gas is been delivered but there’s no spark to ignite. Im going to ordered the plugs as they don’t have them in stock, clean the throttles and MAF’s to then proceed resetting the ECU and verifying the fuses once again, lastly dump 2 gallons of fuel before trying again. Hope it starts; if not then maybe the crank position sensor next or the cam position sensors???? I’ll hate to think it might be the ECU needing to be reprogrammed as I had it flashed with Uprev and most likely will lose the tuning. Without to mentioned ILL HATE TO TAKE IT TO THE DEALER if that’s the only choice. Not only because they will charge and arm and leg and possible talk nonsense blaming the ECU did not have the factory tune but also start throwing things around and messing my car up. Thoughts or comments are appreciated guys.
