I have the HKS MTS-6 harness used to tap into the stock ignition switch harness so you don't have to cut the stock wires. I took it out and plugged the stock harness (back to stock). Car started up fine for a few days but the problem came back and happens intermittently. I also put in a brand new ignition switch.

The only thing I haven't tried is to remove the alarm system. Is anyone experiencing this problem that does not have an alarm system? That would save me the trouble and rule out that issue but then again it could be a problem for but nobody else.

 

reading this was very interesting as I'm struggling with a similar non start issue with my 1999 XJ8. I have change the BCM, battery, fuse , relays, one fuse box, etc. I wonder if this is the same issue?

 

I had to go find my password from over a year ago just to log in and say thank you. I've been trying to figure out what the heck is up with my 03 gsr for such a long time and after going through 3 starters, all new wiring/terminals and I-dont-know-how-many-batteries/jumpstarts, this fixed everything in literally 10 minutes. I can finally take the car somewhere that may involve turning it off (like.. everywhere). I was so excited it worked, I left to get gas and promptly got pulled over

Thank you for sharing this!

 

Hoping this is my problem, along side with the possibility the turbo timer is causing a problem. Either way that timer is being sold as soon as it's out anyway, thank you for this thread. Been having this issue for MONTHS!

 

Honestly I did two other things at the same time so I'm not sure which actually worked. I cleaned the connectors to the battery and actually had to switch the positive side to a new connector. Which sucked because only mitsubishi sold it. And I took out the turbo timer also. Later I found out the harness that the previous owner made was starting to crap out.. So after I did the ignition fix, the battery connector change and removal of the turbo timer my car is running like a champ. I'm not going to question it and just ride with it lol

 

Thought I'd echo other experiences with their Turbo Timers. After the Evo continued with intermittent starts I narrowed the electrical drain to the Apexi Turbo Timer. Disconnected the MT6 harness and the Evo has been starting reliably for 2 weeks with cold/hot engine bays. Problem was so intermittent I went crazy thinking the hot engine contributed to the no starts.

Before discovering the MT6 harness as the problem I found the switched power source for the head unit was not supplying power when keyed on. Possibly due to my dumb *** pulling the head unit out and tugging the radio harness to death.

List of things I did up to discovering the MT6 harness:
Ignition Switch, Starter, tightened ignition switch screw, relocated Miata Battery to rear, new headunit, ran a new switched power source from cigarette fuse to headunit harness, ground wires, and cleaned all connectors. Knocking on wood...

 

Just want to add that my clutch switch was the problem. I went through the diagnosis process and found that out! I thought it was the key switch the whole time!

 

Here's my intermittent problem: I can turn the key to the start position and nothing happens, it doesn't crank over, not even a 'click'. BUT while holding the key in the start position (still not cranking over or even making a 'clicking' sound) I slowly try and move the key in a circular motion (the entire key cylinder, moved it clockwise in my case) and it will then crank over and start. To further explain what I'm doing, the actual ignition cylinder does not move but maybe a butt hair, but this is the motion I do to start the car on occasion and it seems to move just enough to get it to start.

I hope I explained myself well enough so you guys can picture what it is I am doing.

Not sure if the FIX in this thread will cure my intermittent problem. I thought I would ask first before trying this fix.

Anyone else have this issue?

 

See post #83.

 

After a new starter, new wiring harness to the starter and a new battery it is finally fixed also.
Thanks so much I tightened it and WAMMO! Not a starting problem anymore!!!!!!
Thanks a million!!!

Was getting so frustrated I bought another vehicle.
Jeep Grand Cherokee SRT8. Now to keep or sell. He'll I'm such an AWD junkie
I'll keep both beasts!

 

I've had this lingering with turning the key and sometimes nothing and sometimes it starts. I tried the fix above (looping cable ties around the electrical socket and steering column) and now it starts at every turn!

 

With the Jeep, the same thing will happen a different way. The switch down by the PRND shifter which lets your car start only when in P or N - that will loosen up and move about .005" and then you'll have to find the magic position with the lever that lets your car start. Just thought you'd like to know.

 

I been living with the same starter issue with my 05 Lancer... just a plain old lancer, but the same problem. Mechanics were never able to identify the problem so I've been searching online for a while... it wasn't until I found this forum that things made sense. I did exactly as instructed (zippy ties and all) and it seem to have fixed the problem. My Lancer would have starting problem 50% of the time when the car is warm, but it's been 5 days since I did this and it started every time. Thanks so much for sharing!

 

Omg I thought it was just my car thanks everybody!
