2006 FX35 engine won't start immediately

Postby TB-13 » Thu Feb 09, 2017 11:05 am

Hi all,

I have a 2006 FX35 with 135,000 miles on, properly maintained with no major issues all these years that I've owned it. However, 3 months ago I noticed that the car wouldn't start with the first crank. It would take two or three (sometimes more than that) cranks to start. I replaced the battery but the problem was stll there and decided to take it to the mechanic. He said that it was the fuel pump. We replaced the fuel pump but nothing changed. Has anybody else experienced similar issues? If so, any ideas/recommendations?
Thanks in advance!
TB

I have this issue with mine as well ( I have 126K on my '06). There is a fuel relearn procedure you can do that will reset the fuel/air mixtures and will help startup, I've done this and it helps. I have to do it again because the problem is starting again. One thing that might help as well - that I've not tried - is cleaning (or replacing) the mass air flow map sensor.

Try these:

For what it's worth, I disconnected my battery to install a newer steering wheel and my fx has been starting up without a hiccup since. You can probably get the same benefit from doing the above...Or, just unplug your battery for 15 minutes! :D
