Hi Folks. My '98 Accent was running fine until about 3 weeks ago. The first symptoms were stumbling badly on startup (sounded like it was only running on 1 or 2 cylinders) then would catch after about 3 seconds and run fine. It did this intermittently for 3 times then quit altogether and won't start at all. The timing belt is good and all the cranking leaves a strong fuel smell up front so I think the pump is okay. I'm suspecting either the crank or camshaft position sensors. My question - is there a way to test these sensors to see if they are functioning ok? I don't want to just start replacing parts without some indication that one is faulty. Thank you.
