I have a 2000 Mazda Millenia S that I have been having trouble with for about 6 months now. First of all the car would lose power while driving and go into limp mode. After going to several shops, I took it to the dealer and they determined that it was the ignition coils. So we replaced all 6 of these. Not a cheap investment!!

So it ran great for about two weeks and then one day after driving it about 15 miles to work in the morning, I was ready to go home in the evening and it wouldn't start. I had it towed to the dealer and it started up for them the next day. So I was stuck with a tow bill!!

I can drive the car for two to three weeks at a time and it will start everytime. But occassionally it will not start for me after driving to work and it sitting in the parking lot.

Now yesterday it wouldn't start for me (for the second day in a row). But two days later is started right up and the temp here is 5 degrees.

I am at a total loss on what to do to fix this problem. The dealer thinks it is a possible fuel pump or relay problem, but they said that they really don't know. Can someone please help me with this?

Thank you,

Tony
