05 occasional hard starting
my 05 WK recently became hard to start occasionally. new battery and diagnostics show no problem. it will start fine for days then wont. cranks and acts like a fuel problem. after 3-4 tries it starts. changed the fuel relay with no difference. once started it runs perfectly. of course when in the shop it starts fine. I am new to the form but desperate to find a solution. I will check back but if you know of this problem please email me firstname.lastname@example.org
Connect an oscilloscope to the crank and cam sensors and check to make sure that they are operating correctly. Also, connect a fuel pressure gauge to the fuel rail and see if the fuel pressure is within specification.
