QuestionHi Anthony,
I have a Mitsubishi Galant, 1994, engine 4g93, chasise52a, automatic, a short series as I have been told. It runs perfectly for the last 4 years with the normal maintenance.
All started 4 month ago when the computer (due to a condensator leaks) stopped the engine. As a new one is hard to find in NZ (and expensive) I found a guy specialized in fixing computers. He fixed it and the car worked well for 2 weeks. Now, the engine started to be cut suddenly while driving, first days/weeks 1-2 times per day and finally (after 1 month)after few hundreds meters (driving). It could be started again after 1-2 minutes of waiting, but starts hardly;
I had the car checked by 3 Car stations including MITSUBISHI DEALER in Auckland but nobody was able to find out what is wrong, they just charged me for labor (I paid until now about NZ$800). I replaced the Distributor cap and coil, plug sparks, all filters.
Also, the error shown by the diagnose tool shows an error no 64, which is an overflow of petrol and you can feel the smell when you try to restart the engine after it stopped.
A friend of mine had the same problem but with a Nissan March and he found the problem being an Relay under the dashboard. I had a look at my Mitsubishi and I found 3 Relays under the wheel/dashboard/. I found one being for hazards lights and the other two for "Power?" (It’s a serial no: MB629080156700-0110).
I noticed that when the engine is cut if I turn the ignition key few times without to ignite, there are few clicks in one of these relay and after that the engine starts.
Not sure if I have been too clear (English is not my first language) but if you can give me an advice I would appreciate it a lot.
PS I have the assurance the computer works well.
Also 2 of my friends which had before Mitsubishi had computer problems and after that they couldn’t fix the car anymore (even with a new computer).
Best regards,
Adrian
AnswerAdrian,
This issue may be caused by a fuel injector not flowing properly or even a vacuum leak in the intake system or an emissions line. Unfortunately, only a mechanic working on the vehicle directly would be able diagnose the problem. I'm sorry to hear not even the Mitusbishi dealership could figure out the problem. If you suspect it may be one of the relays under the dash, those are relatively and easy enough to replace. You can ask mechanic to specifically test your fuel system and correspoding components, which may reveal the cause of the problem. Sorry I couldn't offer more help.
Good luck!
