Its either one of 2 things. A shorted glowplug is backfeeding and shutting off the timer or the timer is bad. You should start by removing the glowplugs and testing them.

The glowplugs can melt with this test so don't overdo it. Use a set of battery jumper cables and put the NEG on the metal case without damaging the threads. Then take the POS cable and touch the top of the glowplug. Its a matter of comparision. A dark glowplug is cold or dead. When you get a good one you will see an intense glow. Replace the bad ones.

After reinstalling the glowplugs try starting your car. If it still does not work well trace all of the glowplug wires up to a timer box. There should be a Power source going into the Timer. Measure the Voltage going to the Timer. If it is less than Battery Voltage follow the Power wire to a Relay. The Relay may be in the blackbox full of Relays under the hood or independently hung next to the Timer. Sometimes thoughtful Engineers put labels under the lid for each component. Check the plugin sockets for corrosion or replace the Relay for the glowplug Timer.

If you had battery Voltage at the Timer most likely the Timer is bad. The Timer should keep your glowplugs on longer the colder the outside temperature is. The exception is a warm engine. Good luck on your repair. I hope you find my solution very helpful.

hard starting in cold weather for a diesel is an indication of failed glo-plugs. IF it start ok now then the light was telling you of the glo-plug problem. I would only change injectors as a very last resort as they are very expensive and may not be the fault any way as the easy start indicates no fault there.

There is a safety switch on top of the brake pedal lever or clutch lever which is suppose to prevent lurching on start-ups. It is suppose to insure that the Brake pedal is pushed OR the clutch is down before the engine will crank.

The Ignition switch is interrupted by the above cutout switches. But when Ignition is turned on, the Glow plug timer should click and cycle if Power Relay is giving it juice. So if you do not hear that type of clicking, the glow plugs will stay cold.

I would check to see if power is going to the Power Relay above the glow plug timer, and if it is getting power, does the Power Relay send it to the Timer? The starting circuit is more involved in a Diesel because the fuel must be atomized by heating it for initial starts. But you must be getting this process if jumping the solenoid results in the engine starting.

Therefore the big test is whether the small wire to the starter solenoid is dead when a foot is pressing the Brake or clutch pedal when the Ignition key is in the STARTER position.

So either your Ignition switch is bad at the STARTER terminal position or the signal is interrupted by the anti-lurch Interlock switch. It is quite common for problems with this switch being hit and broken or displaced by the Drivers' feet.

There was also no indication of whether you jumped the solenoid on a warm engine which could atomize the fuel by compression or a very cold engine which needed the glow plugs to work.

Please comment on my info and report your success.

2003 SDi Volkswagen Polo, hard to start in mornings. Changed air filter, glo plugs, fuel filter and no change. I read the code with the OBD scan tool and I got code PO113 IAT sensor 1 Circuit High inp


Have that sensor checked or replaced. If the computer gets the wrong input signal from the intake air temperature sensor, it may not realize the engine is cold and not delivering enough gas at start-up.

Glo plugs don't seem to be getting hot when I hold the button down ... it will however start with star ya bastard ... once the enging is hot it will start no problems


GLOW HAS TO BE WORKING.BECAUSE ENGINE STARTED.GLOW PLUGS ARE USED ON COLD START UPS.GLOW PLUGS PREHEAT THE AIR IN COMBUSTION CHAMBER SO DIESEL FUEL WILL START TO BURN ON START UP.WHEN YOU TURN ON IGNITION SWITCH THE GLOW PLUG LIGHT WILL TURN ON FOR MINUTE UNTIL PREHEAT DONE.GLOW PLUGS WILL STAY ON UNTIL THE COOLANT TEMPERATURE GET OPERATING TEMPERATURE.THEN THEY TURN OFF.

Will not start on cold mornings i know it is the glow plugs just want to know how to change them


not sure they have glo plugs, isn't there a heater coil integrated into the injectors?
If you do have glo plugs they are going to be a line of spark plug looking things connected by a wire, you disconnect the wire and unscrew them. You can check them first by removing the wire and doing a continuity check with a multi meter this will indicate if any have gone open circuit

2003 toyota avensis diesal . dificult starting from initial start


I am assuming this a cold weather only issue ?? Turn your key to on before cranking it over for about 5 sec to let the glow plug heat up a moment. Not allowing the glow plug to warm will wear out your starter.
