Kia Troubleshooting Questions? Ask a Mechanic
Hi Im David, sorry for your issues. You will need to remove the fuel pick up and level sensor from the fuel tank and clean the filter from debri and contamination...that will take care of the p1188. for the p0504, the brake switch under the dash attached to a brackey along side the brake pedal will need replaced or adjusted.
place the shift lever in neutral and see if it will start
you will need to check the fuel filter then
theres also a filter in the tank
i believe there is access through a plate under the rear seat....let me check for sure
im not sure about the diesel as i have no information for that here in the states, but it is accessible through the floor on a gasoline model
