On a high energy ignition, possible problems include: Faulty keyswitch, faulty wiring or connectors, faulty pickup inside the distributor, faulty electrical condenser, if it has points (depends on the type of HEI) the points could be bad, faulty coil or faulty HEI control module. You will need to identify which component has failed.
faulty distributer, bad earth terminal on batterie also body controle unit ontop of park brake can stop injector pulse, early to late 90 models
Rear defrost has nothing to do with the engine. Possible causes, low in coolant, faulty thermostat, air lock in the coolant system, faulty temp. switch, ( manual or electronic?) inside car. Did you replace anything? Add any antifreeze? Change any hoses?
The temp sending unit on the engine could be unplugged or faulty.
It may be that the engine coolant temprature sensor has gone faulty. It may well be sending the wrong signal to the ECM causing the ECM to think the engine is hot when in fact the engine is cold.
if your thermostat was bad your engine will over heat but it has nothing to do with the fan,fans are driven by a diffrent mechanism. try checking your thermostatic switch/ heat sensitive switch or sensor, located somewhere in the cooling system(radiator,engine block or thermostat housing) which is the one that tells the fan when to come on.(only electric fans)it may be faulty wiring
Faulty sensor get it replaced if not check to make sure wire isn't shorting out
Car had a faulty immobilizer that caused the problem.
engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty. engine coolant temperature sensor is faulty.
Fluctuating temperature is almost ALWAYS caused by a faulty thermostat. Replace it as soon as possible to avoid engine damage. Variations in idle speed can often be caused by a faulty EGR assembly. Have it checked.
bad plugs, wires, distributer if it has one, bad igniter, faulty wiring.....
through a cracked heater core - possible.
possible faulty leak detection pump
Bad coil, Bad damaged or unplugged crank/cam position sensor, bad rotor, distributer cap, faulty distributer, plugs wires
Most common possible problems: 1. Ignition coil faulty 2. EGR valve clogged/sticking 3. Engine Coolant Temperature switch malfunctioning 4. Vacuum leak Also check fuel pressure, hot and cold, to determine if fuel filter is clogged and/or fuel pump is faulty.
Possible causes of gauge not working. Faulty gauge Blown fuse. Open circuit in wiring to the gauge. Temprature transmitter in engine faulty. ( most probably the actual fault ) Lack of coolant in the engine.
No, they are replaced when faulty.
The television you sold me is faulty.The faulty wiring was replaced.
