If this flashing goes away after a few minutes, this is normal. The glow plugs are on a timer and when the timer works a light should cycle on the dash. Often there may be a clicking noise and the lighting system may flicker when the glow plugs receive power.
. Check for voltage on the Orange/Black wire in the C89 connector. The C89 connector is under the left side of the dash. 2002 Mitsubishi Galant, ES 2.4L, L4, VIN G, Des 4G64, 16V, USA * Electronic Timer Alarm Control (ETAC) Module Wiring - Missing a power to the ETAC. you posibly need to replace

Sounds like the timer is bad. Since you have power when warm, the power relay must be giving the timer juice. The way it is suppose to work is you wait until the glow plug light goes out and then try to start. In cold weather it should take longer for the glow plug light to go out.
You need to check the Relays for the Glowplug timer. The info would be in the Owner's manual or Online at Autozone.com. If using Autozone, toggle down to the HELP menus after registering your car.
The car may have both a Power relay for the Timer and a Timer relay. You would refer to the wiring diagrams and see if the Timer is getting power from the Power relay. The Timer will usually "click" several times to warm the glowplugs.
Unless there is a problem with the Ignition switch, the Power relay or the Timer should be activated by turning on the Ignition switch. Again, the Timer will only work for a limited duration based on engine and air temperature.
If the timer and power relays appear to work, you may have a problem with the starter Relay. There are Interlocks to prevent the starter from turning unless either the brake pedal is pressed or the clutch is depressed. Often there are switches on these 2 levers.
I hope I have answered your question, please rate my info.
Hello, Follow your Glowplug wires back to a box and that box is your Timer. You should have wires going into the Timer from either the Ignition or from a Relay between the Ignition and the Timer.
When you turn the Key to Run, there should be power going into the Timer box. If there is power going in and nothing is happening, then the Timer is bad. If there is no power going into the Timer, work your way up to the Relay.
On your truck the Relay should be a DY 861 Motorcraft. It will look a little like a starter Relay. Check the power in and out, there is a fuse in the panel for this too! But if the fuse blew it will probably do it again until a bad part is replaced.
Okay, If this noise happens when you turn the Key to start, your Starter Relay is bad. Now the other possibility is the Glowplug Timer. When you start a Diesel there is a pause in the initial cold start. You turn the Igniition Key to Run, then let the Glowplug Timer cycle. This cycle sound will be a series of clicks which also may cause the lights to dim.
The glowplugs absolutely must warm up to start a cold diesel engine. There should be a light on the dash which either goes off when the glowplugs are ready or a light will turn on when they are ready. It is only after that activity that you will turn the Key to Start.
Since Diesels take more power to Start, there are 2 batteries. As with a single battery system, every connection must be clean. If the Glow-plug Timer is working and you only get clicks by turning your Key to Start, check the things I said earlier. Your Starter Relay and the big cable connections.
If after all of that, the engine will not turn over and only clicks, jump the Starter Relay with 1 cable from a jumper cable set from the Positive Battery cable post to the Starter Relay on the Starter wire connector. Make sure the truck is in Park or Neutral. If the Starter jumper cable sparks and the Starter does not turn, the Starter is bad. If the Starter spins it confirms the Relay is bad.
I hope my Solution gets you going and that you consider this helpful.
Looks like your timer is switching by itself and kept giving power to the glow plugs.
Better bring that to a car electrician the problem would be the timer relay is stuck or the ignition switch for timer is keep giving power to the timer relay.
Thus, power from the engine lost when in compression.
Hope that helps you out!
