inside the dash behind the glovebox...honesty you should look at the battery ground as is connected to the rest of the car...this point (end of the 1/0 cable) is critical...welds itself with each start as it pulls over 300 cold cranking amps to start the engine...sadly they couple the needs of the ignition, fuel pump and dashboard, ECU----ON this leg of your ground from the battery~...use a wirebrush on the end of the 1/0 cable as it attaches to the frame/fender...thank you~

Get a New battery if yours is older than five years old (knock-off labels on top of battery)...with a clean, wirebrushed GROUND connection the ECU (and a new battery) will act normally then~
