Chrysler Repair: 1993 CRYSLER CONCORDE 3.3L: no start, spark plug wires, crankshaft sensor


Question
HEY WAYNE, I HAVE A 93 CONCORDE ITS NOT GETTING ANY GAS FLOW AND NO FIRE. I'VE REPLACED COIL PACKS, CAMSHAFT SENSOR, CRANKSHAFT SENSOR, FUEL PUMP, AND SPARK PLUG WIRES. DO YOU THINK IT COULD BE THE COMPUTER BOX? IF NOT WHAT ELSE COULD IT BE?

Answer
Hi Kalon,
Have you checked fuse B (20 amp blue) in the power distribution box under the hood? That is main circuit for the computer and the automatic shutdown relay and if those don't get power the engine won't spark or run. Do you hear the fuel pump run for about 1 second when you first turn the ignition key to the 'run' position?
That fuse could be the reason for not fuel or spark. It is the fourth from the front on the inboard row of fuses. Look carefully as it may have a fatigue crack. Do you have a voltmeter to measure circuit conditions?
Let me know.
