i have a klze straight neck on my mx3 and i heard that klze ignitions need a mod .i took this 2 pics to show my disty.can somebody tell me if its a jdm one or a usdm one.does this one need a mod to work right?
car runs normal but it takes about 3 to 4 sec to start.(it has a walbro 255)

Not sure about the mod part, but i had the 3-4sec starting issue until this week, I finally broke down(me not the car) and bought the TOT57171 disty which fixed the problem, urs is the TOT57271 which is the one i used to have.

The JDM ignition system uses an external ignitor and coil from the factory. So, you would see a 7th lead on the cap which would go to the coil. There is a way to make them work using an aftermarket coil and GM HEI ignition module. This is commonly referred to as the "HEI Mod".

What you have there is a standard issue A-spec distributor which is most likely the one that your MX-3 was born with. They often fail because the coil and ignitor are inside the distributor which gets very hot as it is bolted to the engine. That distributor can also be made to work using the HEI Mod, thought the wiring is slightly different. So when your internal coil and/or ignitor does crap out, that's what you should be searching for. It has been explained over and over...and over again. And then again...for the slow kids who didn't get it the first 3 times.

That looks like an obd2 disty. Its bigger than the k8 but its the same as far as having 6 ports. I tried it and it didnt work for me.

why didnt it work for your car?how can i be sure its a obd2 disty?

I dont know why it didnt work


Im sorry not an ob2 disty.. what was I thinking off... anywho... I dont know why it didnt work, i swapped it out fot my stock disty and it cranked right over. I think I still have that disty somewhere.

the 3 pin pulg is wired in a different order from year to year. It has all the right wires, they just don't match up to the position of the wires in your harness.

That disty is missing the cam position sensor, KF34, so it takes a couple of seconds to start cuz the ecu is looking for it and cant find it. The K834 looks identical but has the cam position sensor, I just went through this and have been dealing with it for a couple of years now. The one he has is for a 95 mx-3, the one he needs is for a 94-95 mx-3. As soon as I put the proper one one by car (k834 tot57171) the starting problem went away.

If it needed an external coil then it would never start.

Also if the 3 wire plug was different it would never start.

Ive gone through approx 6 disties in the last 3 months before i said f-it and paid $500 for the proper one i mentioned

So you're saying you had an OBD1 car with an OBD2 disty and it started even though "the ECU is looking for (the CPS) and can't find it"?

On cars which use one, the CPS is the trigger for the ignitor. A car whose ignition system uses the CPS to trigger the igniter will never start with a disty that does not have one. If it takes 3-4 seconds to start the disty is right for your car, but something is wrong with it.

the car having a 255 pump and running rich maybe thats the problem i really dont know

Yes the car will start that way, it uses the cps to start it, however if cranking long enough it will pick up the crank position sensor and still start, but throws a cel code, and you run in limp mode cuz the timing wont advance or retard cuz it cant see the cam ps.

Seriously I installed the K834 TOT57171 disty on wednesday last week, from the KF43 TOT57271 disty, and all my starting issues went away. The car would start but EVERY time it would crank for about 4sec before firing and i had the according cel code, now it starts perfectly and no cel.

damn this means getting another disty

damn i hate this car!!ok so i got a used disty of a 93 that works and got it on my car and now it dsnt start so i switch bak to the 95 obd2 one and it starts(still have the 4-5 sec delay to start)do i need to change any wires to make it start with 93-94 disty????please help me out with pics or something im going mad!!

Yes you need to change the wires on the 3 pin plug, but i dont know which 2, and i couldnt get a straight answer from anyone so i bought the proper disty instead. Good luck
