Other Fuel System Pump problems of the 2003 Chevrolet Impala

2003 Chevrolet Impala 3. 4l is difficult to start, replaced many parts to try and fix: fuel filter, fuel pump, spark plugs and wires, oxygen sensors, fuel evap valve, and throttle control. Vehicle currently has 52,xxx miles. Security light flashes, was able to pull error code p1626: theft deterrent fuel enable signal not received. Keys are original to car, I have tried to re-learn keys to vehicle with no success. Numerous repairs are listed under this error code, including the replacement of the bcm, and this doesn't always fix the problem. This issue needs to be researched further.

Under the hood fire and unintended key rotation. Maybe 5 days after I took my vehicle into tc chevy (in ashland oregon) to have the 2 recalls repaired on it. I tried to start my car and it caught on fire down by the front bumper and the flames made it to the back side of the motor and ignited the fuel lines causing a Mini explosion under the hood, mean while I'm sitting in the driver's seat. I jumped out of the car nearly having the life scared out of me, I popped the hood and grabbed my house garden house and started to try and put the fire out and minimize the damage to my vehicle while I waited for the fire department to reach my house. The fire department showed up and was able to get the fire put out almost torching one of the firefighters head when the fuel pump kicked on without the keys in the ignition and started shooting gasoline reigniting the fire. I'm lucky the fire didn't burn down my house and my neighbor's house that day seeing how the fire caught the bush next door on fire and there was flames 14 ft in the air. See chevy and gm have been trying to act like the fire and the damage to the vehicle is my own fault and none of their own even though the technician says none of the repairs were actually done. I've been trying to get an investigation done and they're trying to push my claim aside and sweep it under the rug. My vehicle was parked in my driveway at my home right next to a bush not my neighbor's house is right up against. Please look into this so that it doesn't get swept under the rug. Please help me. I also have the firefighters report.
