Nothing works? How about the headlights, do they work? If yes, then start checking all fuses in the Power Distribution Center or Box under the hood. If no, then look for a bad maxi-fuse in the PDC, and check for a bad fusible link between the battery and the PDC. The battery positive cable goes to the starter, but a pigtail lead off the positive would go to the PDC, to distribute power to all the various circuits on the car. When you turn the key to on, does the dash light up? If yes, at least power is getting to, and going through the ignition switch. One could then check for power on the starter solenoid wire when key was held in crank or start position. If nothing when turning key to on-no dash lights, nothing-then check for an ignition fuse in the PDC. If fuse is good check for power being available at the ignition switch connector. If no power there, check wiring between PDC and the ignition switch-if power is up to the switch, but nothing happens with key on, no dash or warning lights, then could have a bad ignition switch. It just sounds like a maxi-fuse has blown, or a bad fusible link. Good luck.
IF BATTERY CABLES OLD THEY WILL CAUSE POOR GROUND HIGH RESISTANCE IN STARTER CIRCUIT CAUSING STARTER NOT TO CRANK ENGINE.CHECK TO SEE IF DASH LIGHTS AND GAUGES WORK WHEN YOU TURN ON IGNITION SWITCH IF NO CHECK IGNITION FUSES.IF FUSES OKAY IGNITION SWITCH IS OPEN NEED REPLACING.NOW IF BATTERY VOLTAGE IS 12.6 VOLTS, BATTERY CABLES GOOD AND IGNITION SWITCH AND FUSE OKAY. STARTER SOLENOID OR STARTER FAULTY.REMOVE STARTER TAKE TO ANY AUTO PARTS STORE THEY WILL TEST STARTER.TURN OFF RADIO BEFORE REMOVING NEGATIVE BATTERY SO YOU WONT LOCK OUT RADIO.
IF BATTERY CABLES ARE OLD REPLACE THEM.OLD BATTERY CABLE WILL CAUSE HIGH RESISTANCE IN CRANKING CIRCUIT.CHECK STARTER FUSE.IF DASH LIGHTS DONT LIGHT UP WHEN YOU TURN ON IGNITION SWITCH.CHECK IGNITION FUSE.IF FUSE OKAY.YOUR IGNITION SWITCH COULD BE FAULTY.
CHECK BATTERY VOLTAGE IT SHOULD BE 12.5 VOLTS.IF NOT BATTERY WEAK NEED CHARGING OR REPLACED.IF BATTERY GOOD.TURN IGNITION SWITCH TO ON POSITION WITH ENGINE OFF.DASH LIGHTS SHOULD LIGHT UP IF NOT.CHECK IGNITION SWITCH FUSE.IF FUSE GOOD YOU HAVE A BAD IGNITION SWITCH.IF SWITCH IS GOOD.I AM LOOKING IN FAULT IN STARTER SOLENOID OR STARTER.OR BATTERY CABLES NEED REPLACING.WARNING TURN OFF RADIO BEFORE DISCONNECTING NEGATIVE BATTERY CABLE SO YOU WONT LOSE RADIO PLAYING CODE.
if car wont start.make sure your battery volts are 12.5.if not charge battery.or replace it if dont hold a charge.if battery is good engine wont turn over.make sure battery cables is clean and tight if all good no start .have starter and starter solenoid check.if battery and starter is good.check for fuel .has some one turn ignition to the on position.go to rear of car listen for fuel pump noise.if your hear fuel pump check ignition system for spark.go to auto parts place buy a spark tester.if you get no spark .check .ignition fuses and ignition module.if you hear no fuel pump.replace relay or fuse.if if fuse and relay good replace fuel pump.if every thing good .your car could have crank sensor problem. or your car is in theft deterrant mode.if so have your car towed in and scanned.
