Check your fuel filter if it needs replacement. Empty it out then connect it back. Try to start it again. Inspect the fuel filter if it filled with gasoline. Check if there is noise at the fuel tank to check if the pump is working. If it did not, inspect the fuse for your fuel pump and the relay. If both are good you may connect the fuel pump directly to the battery to see if it works. It may be a bad wiring.

It is possible that the harmonic balancer is slipping back into the timing chain cover making the scraping noise. If the vehicle has electric fans, a fan motor could be bad.

Try the Driver Door Module fuse 15A

Always disconnect the battery before performing any maintenance on the vehicle. This will prevent you smoking something important.

Autozone , advance etc.... can not read these code's . Which transfercase does it have ? Transfer Case - BW 4482-NR4 Transfer Case - NVG 246-NP8 How many buttons for 4X4 three or four ? The BW 4482 transfer case features a 3-button shift control switch located on the instrument panel The NVG 246 EAU transfer case features a 4 button shift control switch located on the instrument panel When the ignition key is in the RUN position, the transfer case shift control module monitors the transfer case shift control switch to determine if the driver desires a new mode/range position. At a single press of the transfer case shift control switch, the lamp of the new desired position will begin flashing to inform the driver that the transfer case shift control module has received the request for a new mode/range position. The lamp will continue to flash until all shifting criteria has been met and the new mode/range position has been reached, or has been engaged. Once the new mode/range position is fully active, the switch indicator lamp for the new position will remain ON constantly.The 4X4 system with four button shift control can set a number of DTC'S DTC B0790 DTC B2725 DTC C0300 DTC C0305 DTC C0306 DTC C0321 DTC C0327 DTC C0359 DTC C0374 DTC C0379 DTC C0550 The three button switch can also set an store a few codes DTC B0790 DTC B2725 DTC C0306 DTC C0327 DTC C0329 DTC C0359 DTC C0550 Without knowing if any of these DTC'S are stored can't suggest any type of repair .
