Coming back from Oregon I threw a check engine light. Come to find out its a bad MAP sensor. I replaced the sensor and needed to clear the code. I used my buddies sct tool made for fords. I plugged in to my 02 f350 and read the codes. Then I cleared them. I pulled the sct out of the OBD port and went to start the truck. It had a very slow crank. I cycled the key again and now my gauges cycle and the dash lights come on for a split second and then shut off. Go to start the truck and get nothing but a click. Checked fuses and found only left side of fuse panel to be getting power. Currently have P0562, P1000, and P0381 codes active. Reading bat voltage on the sct, it reads 15. I need help! Im lost and confused and just want to drive my truck.
