Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
What sort of vehicle is this we are working on?
Thanks.When the problem is occurring and it won't start, do you have spark while cranking?
Thanks.I know you mentioned changing the crank sensor... when you did, was it with a genuine Mitsubishi sensor purchased from a dealership (nothing from an auto part store, even if they swore it was genuine)?
Thanks.Before doing anything else, lets get a genuine Mitsubishi crank sensor on there.
When it comes to losing spark you only have a few possible options... the crank sensor of course, the computer and the ignition key (after repeated attempts to start with the wrong key), and of course the wiring in between and fuses etc.
The wiring isn't going to come and go like that, nor is a fuse failure. A key problem would not show a spark loss until usually 20-30 attempts (it shuts down fuel first then only spark as a last effort to prevent theft) nor does it usually come and go.
The crank sensor however.... would behave this way, and aftermarket crank sensors are 100% known for this problem on Mitsubishis. There is basically no such thing as a good aftermarket hall effect type sensor for Mitsubishis.
Lets get a genuine crank sensor on there and re-evaluate... you should resolve your current issue doing that.
