Question about 2003 Mitsubishi Diamante

1 Answer

2003 MItzubishi Diamante wont start when wet.

Basically the car will work great from 39 F and below and 55 F and above. However, whenever in the winter, when the snow melts between 40-54 F the car will turn, but not start. I have changed the battery. It is also very wet out when it does this. Once I was driving and hit a puddle and it died. Any ideas. I am only a little mechanical, but can do basic fixes, ie brakes, tune ups, oil change. Any chance I can fix this?

Try checking the wiring loom that goes on the ignition coils for humidity as your problem seems to be a humidity ingress in the wiring.

My 2003 mitsubishi diamante will crank but it wont start


Lots of possible answers to this but it all falls down to this basic rule with witch to always check these problems. You need three things for a motor to run. Fuel, air, and fire find the one it's not getting and you'll know what's wrong. Hope this helps Chris

Hi your transmission belts and gears are getting to that rebuild the ****** point. Also your lock-up tourqe convertor is starting to mufunction. Amaaco did a great job for me on vehicle, the warranty is worth it.

Try replacing the Oil Pressure Switch/Sending Unit. It should only be a couple bucks at your local auto parts store.

its your distributer cap, have someone look at it while you crank it and ask if they see any sparks, if its crack "just from age, or whatever the case" the plugs wont fire right causen it not to start, 20 doller project an it took me one hour, if its the problem you can do it yourself.. i think that may be your prob. it was mine and my 01 diamante ls wouldnt start in the rain or cold either
