I completed it first. I own a gasoline pump, should that be the problem. Initially attempting the simpler tasks. I hope that is not the gasoline tank pressure sensor, since I am unable to locate one elsewhere. My fuel gauge rapidly decreases from full to three-quarters and remains at that level longer than expected. Similarly, at half tank. No codes are available either. If I need to replace the pump, what is the size of the torque screws on the rear drive shaft? When I accelerate to 4000 RPMs and then release the throttle, the RPMs decrease before the vehicle resumes motion.
