I killed my battery last night, don't know how, the lights were off. I let the charger sit at 6 amps over night, this morning the batt put out
13.22 volts. I attempted to start the car but the fuel pump didn't pump. I can hear the relay clicking. The PCM and fuel pump relay are both clicking, but the FP relay clicks 3 or 4 times. I checked the voltage at C213(I hink - it's the connector behind the right kick panel that sends power out to the fuel pump) and it's only showing 6.8-7.1 volts when I turn the ignition to start or run. Well, next I applied voltage from the charger to the fuel pump at C213 and the pump turned on. If I pressurize the fuel system manually from there, I can start the car and it runs just fine.What the heck is going on? I have two ideas, perhaps someone has more...
I'm thinking the battery may be too weak - The fuel pump relay is clicking so much because there is not enough juice to hold it on. Or, does the PCM keep trying to turn it on because the fuel system is not becoming pressurized?
Perhaps I have a ground loop or something somewhere that is preventing proper voltage? I did recently change some wiring.
This is 93 5.0
