Question about 2004 Chevrolet Silverado 1500 Crew Cab
This truck only has 43,000 on it. It stalls out when either idling or driving. I've changed the cap, rotor and fuel filter. Fuel pump comes on when I turn the ignition on. Not sure what else to do.
Check fuel pressure spec is 55-62 psi anything below will cause it to stall

CODE 43 IS ELECTRONIC SPARK CONTROL -.KNOCK SENSOR.LOOKS LIKE ALTERNATOR NOT PUTTING OUT ENOUGH VOLTS TO CHARGE BATTERY.YOU NEED 13.5 TO 14.5 VOLTS.CHECK ALTERNATOR FUSE AND ELECTRICAL WIRES.MAKE SURE BELTS NOT SLIPPING.IF ALL IS GOOD.REMOVE ALTERNATOR.LET AUTO ZONE CHECK IT.TO MAKE SURE.TURN OFF RADIO BEFORE MOVING BATTERY CABLES.SO YOU WONT LOSE RADIO CODE.YOUR CAR IS NOT GOING TO RUN RIGHT IF THE ECM DONT RECEIVE 12 VOLTS OR 13 VOLTS.
